Pie Chart

This article describes the Pie Chart component and its properties.

Squirrel 1.12 introduced a “Quick Set-up” tab on many property panels. The properties described on this page are available on the “All Properties” tab of the property panel. For more details on “Quick Set-Up” properties see this article

The Pie Chart displays data in the spreadsheet to the user. Use it to reveal trends or progress over time and show many different categories of data. In this article, we will be going over the Pie Chart, one of the many types of charts available to use within Squirrel.

Pie Chart Properties

There are three property drawers available within the Pie Chart Properties Panel - these consist of a DATA drawer, a DATA drawer, and a DYNAMIC VISIBILITY drawer. This guide will not describe the dynamic visibility properties as these are generic to each visible component; a separate guide and tutorial on dynamic visibility can be found here.


  • Values - The area used to select the data in the sheet to bind to the chart. Do this by hovering over the box, and selecting the “bind to spreadsheet” button in the top-right corner.

  • Ignore End Blanks in Values - Toggle this property to ignore end blanks in a selected range. This can be used to hide data that has yet to be added. This is checked by default.
