Chippen charts

Random bar charts for your data driven mockups

This is a Sketch plugin for creating charts with random or user defined data for use in mockups. Change the size of selected rectangles. Chose between random and linear. Works for both horizontal and vertical bar charts. Furthermore, the latest feature allows you to paste text from the clipboard straight into symbol overrides. How good is that, heh?

Made with love by Small Multiples in Chippendale, Sydney.

List of current features

  • Bar chart with random values
  • Bar chart with actual data
  • Paste clipboard text into symbols
  • Apply random fill to selection (new)

How to install

  1. Click the Clone or download button in the top right and choose Download Zip
  2. Save the ZIP file to your harddrive
  3. Open the downloaded file and double click the sketch file chippen-charts.sketchplugin
  4. The plugin is installed and you can use it via the menu Plugins > Chippen charts


1. Random bar chart from selected layers

If you don't have data yet but still want to design a bar chart for your mockup, you can use the option to apply random values. You can also apply not-so-random values when choosing trend up or trend down.

2. Defined bar chart from selected layers

If you have data that you want to apply to your chart this option is for you. You can even copy / paste from Excel columns or rows. How cool is that, right? In case your number values don't exactly match your desired pixel values, you have the option to apply a multiplier or set a maximum height. By default values don't get scaled.

3. Paste clipboard text into symbols

Get your clipboard loaded with amazing text content, fire up the plugin, and let the magic of the plugin paste everything into your symbol override of choice. It's as simple as that.

You might wonder why you wouldn't wanna use the Sketch Data feature for that. The thing is, the Sketch Data feature does not preserve the order of elements, which this plugin does.

4. Random fill

Apply random colours to selected layers or choose to apply colours based on the order layers in order to create a gradient. All that needs to be done is choosing two hex colours and the number of colours you want to be generated.

How the plugin works

Dialog boxes for random and user defined action

Those dialog boxes give you a good summary of what the plugin is capable of. Just have a look at the various input options.


  1. Create desired amount of rectangles
  2. Layers must be in the correct order
  3. Make sure layers are either bottom or left aligned
  4. Run the plugin and adjust settings in dialog window if necessary
  5. The size of you bars will be adjusted


Horizontal or vertical bar chart

Chippen Chart detects wheter you are about to create a vertical or horizontal bar chart using the x and y-position of your selected layers. If there is no common x or y-value it will by default apply the logic for vertical bars.

Min and max size (pixel)

Chippen chart detects minimum and maximum pixel height of selected layers and apply those to the new bar chart. You can also adjust your desired extrema in the dialog window. If all selected layers share the same height the plugin will apply a default value for either min or max.

Trend type

You can choose between 5 trend types. All of them will use the min and max value you define. Random will apply completely random integer numbers. Linear_ will interpolate values between min and max. Natural will do the same while adding a notion of randomness.

  • Random
  • Trend going up ↑ (linear)
  • Trend going up ↑ (natural)
  • Trend going down ↓ (linear)
  • Trend going down ↓ (natural)


Defining a chart with trend going up

Besindes random numbers you can choose between linear trends and natural trends. Natural trends are like linear ones, but they have a little bit of randomeness aplpied to them.

This is how a trend up (natural) chart looks like
