amCharts Export

Version: 1.4.56

Description

This plugin adds export capabilities to all amCharts products - charts and maps.

It allows annotating and exporting chart or related data to various bitmap, vector, document or data formats, such as PNG, JPG, PDF, SVG, JSON, XLSX and many more.

Important notice

Please note that due to security measures implemented in modern browsers, some or all export options might not work if the web page is loaded locally (via file:///) or contain images loaded from different host than the web page itself.

Usage

1) Include the minified version of file of this plugin as well as the

bundled CSS file. I.e.:

<script src="amcharts/plugins/export/export.min.js"></script>
<link  type="text/css" href="amcharts/plugins/export/export.css" rel="stylesheet">

Or if you'd rather use amCharts CDN:

<script src="//cdn.amcharts.com/lib/3/plugins/export/export.min.js"></script>
<link  type="text/css" href="//cdn.amcharts.com/lib/3/plugins/export/export.css" rel="stylesheet">

(this needs to go after all the other amCharts includes)

2) Enable export with default options:

AmCharts.makeChart( "chartdiv", {
  ...,
  "export": {
    "enabled": true
  }
} );

... OR set your own custom options:

AmCharts.makeChart( "chartdiv", {
  ...,
  "export": {
    "enabled": true,
    "menu": [ {
      "class": "export-main",
      "menu": [ {
        "label": "Download",
        "menu": [ "PNG", "JPG", "CSV" ]
      }, {
        "label": "Annotate",
        "action": "draw",
        "menu": [ {
          "class": "export-drawing",
          "menu": [ "PNG", "JPG" ]
        } ]
      } ]
    } ]
  }
} );

Loading external libraries needed for operation of this plugin

The plugin relies on a number of different libraries, to export images, draw annotations or generate download files.

Those libraries need to be loaded for the plugin to work properly.

There are two ways to load them. Choose the one that is right:

1) Automatic (preferred)

All libraries required for plugin operation are included withing plugins /libs subdirectory.

The plugin will automatically try to look in chart's path property. If your plugin files are located within plugins folder under amcharts (as is the case with the default distributions), you don't need to do anything - the libraries will load on-demand.

If you are using relative url, note that it is relative to the web page you are displaying your chart on, not the export.js library.

In case you've moved the libs folder you need to tell the plugin where it is "libs": { "path": "../libs/" }

2) Manual

You can also load all those JavaScript libraries by <script> tags. Since loading of libraries is on by default you will need to turn it off by setting "libs": { "autoLoad": false }

Here is a full list of the files that need to be loaded for each operation:

File Located in Required for
fabric.min.js libs/fabric.js/ Any export operation
FileSaver.js libs/FileSaver.js/ Used to offer download files
pdfmake.min.js libs/pdfmake/ Export to PDF format
vfs_fonts.js libs/pdfmake/ Export to PDF format
jszip.js libs/jszip/ Export to XLSX format
xlsx.js libs/xlsx/ Export to XLSX format

Configuring export menu

Plugin includes a way to completely control what is displayed on export menu. You can set up menus, sub-menus, down to any level. You can even add custom items there that execute your arbitrary code on click. It's so configurable it makes us sick with power ;)

The top-level menu is configured via menu property under export. It should always be an array, even if you have a single item in it.

The array items could be either objects or format codes. Objects will allow you to specify labels, action, icon, child items and even custom code to be executed on click.

Simple format codes will assume you need an export to that format.

Simple menu setup

Here's a sample of the simple menu setup that allows export to PNG, JPG and CSV:

"export": {
  "enabled": true,
  "menu": [ {
    "class": "export-main",
    "menu": [ "PNG", "JPG", "CSV" ]
  } ]
}

The above will display a menu out of three options when you hover on export icon:

  • PNG
  • JPG
  • CSV

When clicked the plugin will trigger export to a respective format.

If that is all you need, you're all set.

Please note that we have wrapped out menu into another menu item, so that only the icon is displayed until we roll over the icon. This means that technically we have a two-level hierarchical menu.

If we opmitted that first step, the chart would simply display a format list right there on the chart.

Advanced menu setup

However, you can do so much more with the menu.

Let's add more formats and organize image and data formats into separate submenus.

To add a submenu to a menu item, simply add a menu array as its own property:

"export": {
  "enabled": true,
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download as image",
      "menu": [ "PNG", "JPG", "SVG" ]
    }, {
      "label": "Download data",
      "menu": [ "CSV", "XLSX" ]
    } ]
  } ]
}

Now we have a hierarchical menu with the following topology:

  • Download as image
    • PNG
    • JPG
    • SVG
  • Download data
    • CSV
    • XLSX

We can mix "string" and "object" formats the way we see fit, i.e.:

"export": {
  "menu": [
    "PNG",
    { "label": "JPEG",
      "format": "JPG" },
    "SVG"
  ]
}

The magic does not end here, though.

Adding custom click events to menu items

Just like we set label and format properties for menu item, we can set click as well.

This needs to be a function reference. I.e.:

"export": {
  "menu": [
    "PNG",
    { "label": "JPEG",
      "click": function () {
        alert( "Clicked JPEG. Wow cool!" );
      } },
    "SVG"
  ]
}

Adding external legend

In case you have an external legend you need to define the position where it should get placed in your export. By default it obtains the dimensions from the container but you can optionally overwrite those settings as shown below.

"export": {
  "legend": {
    "position": "top",  // or "right", "bottom" and "left" are possible
    "width": 200,       // optional
    "height": 200       // optional
  }
}

Changing the dataProvider when exporting

If you want to change the dataProvider when exporting to CSV, XLSX, or JSON, you can use the processData option:

"export": {
  "processData": function (data, cfg) {
    return data.slice(1, -1);
  }
}

Adding overlaying border

In case you need a more visible separation of your chart for further processing you can add an overlaying border.

"export": {
  "border": {
    "stroke": "#000000",  // HEX-CODE to define the border color
    "strokeWidth": 1,     // number which represents the width in pixel
    "strokeOpacity": 1    // number which controls the opacity from 0 - 1
  }
}

Menu item reviver

By passing the menuReviver callback function you can modify the resulting menu item or relative container, before it gets appended to the list (ul). The function takes two arguments and it needs to return a valid DOM element.

"export": {
  "menuReviver": function(item,li) {
    li.setAttribute("class","something special");
    return li;
  }
}

Format specific options that you can override using Menu item reviver

Some formats, such as CSV, have specific parameters that are used when exporting to this format. For example, default column separator for CSV is a comma. But what if you would like to be that a tab? You could use menuReviver for that like this:

"export": {
  "enabled": true,
  "menuReviver": function(cfg,li) {
    if ( cfg.format == "CSV" ) {
      cfg.delimiter = "\t";
    }
    return li;
  }
}

Below you will find a list of parameters that you can override for each format:

JPG

Property Default Available values Description
quality 1 0-1 A quality of the resulting JPG image
multiplier 1 number Set this to non-1 number to resize the resulting image by

PNG

Property Default Available values Description
quality 1 0-1 A quality of the resulting JPG image
multiplier 1 number Set this to non-1 number to resize the resulting image by

PDF

Property Default Available values Description
multiplier 2 number Set this to non-1 number to resize the resulting image by

PRINT

Property Default Available values Description
delay 1 number Delay by number of seconds before triggering print
lossless false true/false Enable or disable image optimization when printing

CSV

Property Default Available values Description
delimiter "," string A string to use as a column delimiter
quotes true true/false Set whether to enclose strings in doublequotes
escape true true/false Set whether to escape strings
withHeader true true/false Add header row with column names

XLSX

Property Default Available values Description
dateFormat "dateObject" "dateObject"|"string" Whether to export dates as dates recognisable by Excel or formatted as strings
withHeader true true/false Add header row with column names
stringify false true/false Convert all cell content to strings

Menu walker

In case you don't like our structure, go ahead and write your own recursive function to create the menu by the given list configured through menu.

"export": {
  "menuWalker": function(list,container) {
    // some magic to generate the nested lists using the given list
  }
}

Printing the chart

Adding menu item to print the chart or map is as easy as adding export ones. You just use "PRINT" as format. I.e.:

"export": {
  "menu": [
    "PNG",
    "SVG",
    "PRINT"
  ]
}

Or if you want to change the label:

"export": {
  "menu": [
    "PNG",
    "SVG",
    {
      "format": "PRINT",
      "label": "Print Chart"
    }
  ]
}

Annotating the chart before export

OK, this one is so cool, you'll need a class 700 insulation jacket.

By default each menu item triggers some kind of export. You can trigger an "annotation" mode instead by including "action": "draw" instead.

"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw"
    } ]
  } ]
}

Now, when you click on the "Annotate" item in the menu, the chart will turn into an image editor which you can actual draw on and the menu gets replaced by the default annotation menu.

If you don't like the detault annotation menu, you can define your own:

"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw",
      "menu": [ {
        "class": "export-drawing",
        "menu": [ "JPG", "PNG", "SVG", "PDF" ]
      } ]
    } ]
  } ]
}

Now, when you turn on the annotation mode, your own submenu will display, allowing to export the image into either PNG, JPG, SVG or PDF.

And that's not even the end of it. You can add menu items to cancel, undo, redo and still be able to reuse the choices by using the actions draw.modes, draw.widths, draw.colors or draw.shapes.

"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw",
      "menu": [ {
        "class": "export-drawing",
        "menu": [ {
            label: "Size ...",
            action: "draw.widths",
            widths: [ 5, 20, 30 ] // replaces the default choice
        }, {
          "label": "Edit",
          "menu": [ "UNDO", "REDO", "CANCEL" ]
        }, {
          "label": "Save",
          "format": "PNG"
        } ]
      } ]
    } ]
  } ]
}

Annotation settings

Since 1.2.1 it's also possible to set some of the annotation options without the need to re-define the whole menu structure. You can easily adjust the choice of modes, colors, widths or shapes, and set the defaults when entering the annotation mode.

Following setup shows you all available settings. If you don't have the drawing property at all, it will falls back to the defaults.

"export": {
  "drawing": {
    "enabled": true, // Flag for `action: "draw"` menu items to toggle it's visibility
    "shapes": [ "test.svg" ], // Choice of shapes offered in the menu (shapes are being loaded from the shapes folder)

    "width": 2, // Width of the pencil and line when entering the annotation mode
    "widths": [ 2, 10, 20 ], // Choice of widths offered in the menu

    "color": "#000000", // Color of the pencil, line, text and shapes when entering the annotation mode
    "colors": [ "#000000", "#FF0000" ] // Choice of colors offered in the menu

    "opacity": 1, // Opacity of the pencil, line, text and shapes when entering the annotation mode
    "opacities": [ 1, 0.8, 0.6, 0.4, 0.2 ] // Choice of opacity offered in the menu

    "menu": [ ... ], // Shown menu when entering the annotation mode

    "mode": "pencil", // Drawing mode when entering the annotation mode "pencil", "line" and "arrow" are available
    "modes": [ "pencil" , "line", "arrow" ], // Choice of modes offered in the menu
    "arrow": "end", // position of the arrow on drawn lines; "start","middle" and "end" are available

    "autoClose": true // Flag to automatically close the annotation mode after download
  }
}

If you need to filter the drawn elements, you can pass the reviver method in your global configuration, or pass it to the capture method if you export manually. For example, to hide all free labels you can simply do something like the following:

"export": {
  "menu": ["PNG"],
  "reviver": function(obj) {
    if ( obj.className == "amcharts-label" ) {
      obj.opacity = 0;
    }
  }
}

Delay the capturing before export

In some cases you may want to delay the capturing of the current chart snapshot to highlight the current value. For this you can simply define the 'delay' property in your menu item:

"export": {
  "delay": 3,

  // or specifically on individual menu items

  "menu": [{
    "label": "PNG",
    "format": "PNG",
    "delay": 3
  }]
}

Events

Since version 1.1.7 the plugin introduces some events you can use. For example the afterCapture event allows you to add some texts or images which can't be seen on the regular chart but only the generated export. Use it to watermark your exported images.

"export": {
  "afterCapture": function(menuConfig) {
      var text = new fabric.Text("This is shown on exported image only", {
        top: 50,
        left: 100,
        family: this.setup.chart.fontFamily,
        fontSize: this.setup.chart.fontSize * 2
      });
      this.setup.fabric.add(text);
  },

  // or specifically on individual menu items

  "menu": [{
    "label": "PNG",
    "format": "PNG",  
    "afterCapture": function(menuConfig) {
        var text = new fabric.Text("This is shown on exported image only", {
          top: 50,
          left: 100,
          family: this.setup.chart.fontFamily,
          fontSize: this.setup.chart.fontSize * 2
        });
        this.setup.fabric.add(text);
    }
  }],

Since version 1.4.29 we have added the onReady callback to get your stuff done right after the plugin or specific dependency is ready to use. Ensure to check the timedout flag to be sure the dependency got fully loaded.

"export": {
  "onReady": function( type, timedout ) {

    // Plugin ready for data exports
    if ( type == "data" ) {
      this.toCSV( {}, function( data ) {
        // Exported to CSV
      } );

    // Plugin ready for image exports
    } else if ( type == "fabric" && !timedout ) {
      this.capture( {}, function() {
        this.toPNG( {}, function( data ) {
          // Exported to PNG
        } );
      } );
    }
  }
}

Exporting to PDF

When exporting to PDF, you can set and modify the content of the resulting document. I.e. add additional text and/or modify image size, etc.

To do that, you can use menu item's content property.

Each item in content represents either a text line (string) or an exported image.

To add a text line, simply use a string. It can even be a JavaScript variable or a function that returns a string.

To include exported image, use image: "reference".

Additionally, you can add fit property which is an array of pixel dimensions, you want the image to be scaled to fit into.

Here's an example of such export menu item:

{
  "format": "PDF",
  "content": [ "Saved from:", window.location.href, {
    "image": "reference",
    "fit": [ 523.28, 769.89 ] // fit image to A4
  } ]
}
Property Description
pageSize a string or { width: number, height: number }
pageOrientation by default we use portrait, you can change it to landscape if you wish
pageMargins [left, top, right, bottom] or [horizontal, vertical] or just a number for equal margins

Styling the export menu

The plugin comes with a default CSS file export.css. You just need to include it on your page.

Feel free to override any styles defined in it, create your own version and modify as you see fit.

If you choose to modify it, we suggest creating a copy so it does not get overwritten when you update amCharts or plugin.

Plugin API

We explained how you can define custom functions to be executed on click on export menu items.

Those functions can tap into plugin's methods to augment it with some custom functionality.

Here's an example:

"export": {
  menu: [ {
    label: "JPG",
    click: function() {
      this.capture({},function() {
        this.toJPG( {}, function( data ) {
          this.download( data, "image/jpg", "amCharts.jpg" );
        });
      });
    }
  } ]
}

The above will use plugin's internal capture method to capture it's current state and toJPG() method to export the chart to JPEG format.

Yes, you're right, it's the exact equivalent of just including "JPG" string. The code is here for the explanatory purposes.

Here's a full list of API functions available for your consumption:

Function Parameters Description
toJPG (object) options, (function) callback Prepares a JPEG representation of the chart and passes the binary data to the callback function
toPNG (object) options, (function) callback Prepares a PNG representation of the chart and passes the binary data to the callback function
toSVG (object) options, (function) callback Prepares a SVG representation of the chart and passes the binary data to the callback function
toPDF (object) options, (function) callback Prepares a PDF representation of the chart and passes the binary data to the callback function
toJSON (object) options, (function) callback Prepares a JSON and passes the plain data to the callback function
toCSV (object) options, (function) callback Prepares a CSV and passes the plain data to the callback function
toXLSX (object) options, (function) callback Prepares a XLSX representation of the chart and passes the binary data to the callback function
toBlob (object) options, (function) callback Prepares a BLOB and passes the instance to the callback function
toCanvas (object) options, (function) callback Prepares a Canvas and passes the element to the callback function
toArray (object) options, (function) callback Prepares an Array and passes the data to the callback function
toImage (object) options, (function) callback Generates an image element which holds the output in an embedded base64 data url

Annotation API

Since version 1.4.27 we've introduced the functionality to manage the annotations on the fly. The setter returns an array of objects, where each element represents an annotation. On the other hand the setter processes the given annotations within options (options.data). Both methods support the reviver callback which allows you to modify the annotations if needed.

Function Parameters Description
getAnnotations (object) options, (function) callback Returns an array of objects where each element represents an annotation.
setAnnotations (object) options, (function) callback Draws the given annotations (options.data).

Here's an example how to insert annotations, please ensure your chart is in annotation mode:

chart.export.setAnnotations({

  // Array of annotations, accepts this simple handwritten format or the detailed output of the getter
  data: [{
    top: 200,
    left: 200,
    text: "Test annotation",
    type: "text"
  }],

  // Allows you to modify the annotation before it's being added into the canvas.
  reviver: function(obj,index) {
    obj.fill = "#FF00FF";
  }


},function() {
  // Callback when finished 
});

Fallback for IE9

Unfortunately, Internet Explorer 9 has restrictions in place that prevent the download of locally-generated files. In this case the plugin will place the generated image along download instructions directly over the chart area.

To avoid having a bigger payload by including senseless polyfills to your site, you may need to add following metatag in your <head> of your HTML document.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

This feature will kick in by default. If you want to disable it simply pass false to the fallback parameter.

"export": {
  fallback: false
}

In case you want to change our default messages you can modify it like following.

"export": {
  fallback: {
    text: "CTRL + C to copy the data into the clipboard.",
    image: "Rightclick -> Save picture as... to save the image."
  }
}

Requirements

This plugin requires at least 3.13 version of JavaScript Charts, JavaScript Stock Chart or JavaScript Maps.

The export will also need relatively recent browsers.

IE10 and up are supported.

Partial support for IE9; Fallback mechanism.

IE8 and older are not supported I'm afraid. Hey, it's time to upgrade!
