How to Customize Pie/Bar/Column/Area/Line Chart Data Labels

If you find yourself needing to modify data labels on a widget, and the built-in capabilities do not allow you to achieve your goal, it might be possible to customize those values with the help of JavaScript. 

Note: The script was developed on L2023.3 Sisense Linux-based version. 

This is an example JavaScript code snippet that could be used to customize the Pie/Bar/Column/Area/Line Chart data labels. In the example below, the script modifies the font size and color of the labels of a Pie Chart. To use it, add it to the "Edit Script" section on a widget level:




The JavaScript code snippet is below:



widget.on('beforeviewloaded', (widget, element) => {
const style = = !!style ? style : {} = '20px' = '#e28743'





Other widget types examples of how the data values are affected by the same script:




Feel free to use this example snippet and customize it further by adding additional parameters to make your widget look the way you need. Feel free to share your experience in the comments!

Dear Sisense Team,

Since I did not familiar about Java Script or HTML.

Can you kindly explain what's the meaning of the following code and what can it do? = !!style ? style : {}

 Thank you.

@Howard hi!

This line essentially checks if the style variable is defined and not falsy. If it is, it assigns its value to the style property of the data labels style. Otherwise, it assigns an empty object {}. This ensures that the style property is always defined before further modifications are made to it. This can be useful to avoid errors if the style is not initially set.

Hope it helps!

Best Regards, Lily
