Angular Dimple

A simple angular library wrapping dimple charts as angular directives.

Install

Manual

To get setup, simply:

1. Make sure you have d3 and dimple
2. Download the minified javascript in dist
3. Include the library as a module in your app

Bower

bower install angular-dimple

Use

All the angular directives behave in pretty much the same way. Simply use the directive, passing in a model from your scope as the data= attribute.

For example, in the controller for your app, if you had something like $scope.graphData which is json that looks like this:

[
  {
    "Month": "Jan-11",
    "storeId": 1,
    "Sales": 14
  },{
    "Month": "Feb-11",
    "storeId": 1,
    "Sales": 14
  },{
    "Month": "March-11",
    "storeId": 1,
    "Sales": 17
  },{
    "Month": "Jan-11",
    "storeId": 2,
    "Sales": 14
  },{
    "Month": "Feb-11",
    "storeId": 2,
    "Sales": 16
  },{
    "Month": "March-11",
    "storeId": 2,
    "Sales": 8
  }
]

You'd set up a line-graph like this:

<graph data="graphData">
  <x field="Month"></x>
  <y field="Sales"></y>
  <line field="storeId" value="2"></line>
  <line field="storeId" value="1"></line>
</graph>

This would give you a line graph with an x-axis of "Month", a y-axis of "Sales" and two lines, each corresponding to a different store from your dataset.

Passing a line tag with a field and no value will draw a line on the chart for each unique value for that field in your data. So you could plot a line for each unique storeId without having to specify them all by name like this:

<graph data="graphData">
  <x field="Month"></x>
  <y field="Sales"></y>
  <line field="storeId"></line>
</graph>

Line Graphs

<graph data="graphData">
  <x field="Month"></x>
  <y field="Sales"></y>
  <line field="storeId" value="2"></line>
  <line field="storeId" value="1"></line>
</graph>

Area Charts

<graph data="graphData">
  <x field="Month"></x>
  <y field="Sales"></y>
  <area field="storeId" value="2"></area>
  <area field="storeId" value="1"></area>
</graph>

Stacked Area Charts

<graph data="graphData">
  <x field="Month"></x>
  <y field="Sales"></y>
  <stacked-area field="storeId"></stacked-area>
</graph>

Bar Graphs

<graph data="graphData" orientation="horizontal">
  <x field="Month"></x>
  <y field="Sales"></y>
  <bar field="storeId" value="2"></bar>
  <bar field="storeId" value="1"></bar>
</graph>

Stacked Bar Graphs

<graph data="graphData" orientation="horizontal">
  <x field="Month"></x>
  <y field="Sales"></y>
  <stacked-bar field="storeId" value="2"></stacked-bar>
</graph>

Scatter Plot

Scatter plots require one extra field (series) to be passed through to the <scatter-plot> element. Let's say you have some data with heights and weights formatted like this:

[
  {
    "Height": 64,
    "Weight": 190
  },{
    "Height": 68,
    "Weight": 195
  },{
    "Height": 69,
    "Weight": 198
  },{
    "Height": 70,
    "Weight": 205
  },{
    "Height": 67,
    "Weight": 198
  },{
    "Height": 76,
    "Weight": 195
  }
]

Assuming you set that on your scope as $scope.scatterData, you can use the following directive to make a scatter plot:

<graph data="scatterData" width="100%" height="600px">
  <x field="Height" type="Measure"></x>
  <y field="Weight" type="Measure"></y>
  <scatter-plot field="Weight" series="Height" label="Group A"></scatter-plot>
</graph>

• Note: the label attribute will make all the points the same color and title the group with that label in the legend if you have one.*
