I have created a Pie Chart. All the information is pulling correctly. I have the colors set in the legend box but I am not able to change the name. It is showing a '3' and '4' next to the color blocks. How can I change these numbers to names?

QuickBase uses HighCharts for it charting package and HighCharts use <svg> technology. This means that irrespective of the features QuickBase or HighCharts has placed into their integrations or APIs, you can always directly manipulate the final <svg> just as you can manipulate a web page's DOM. So sidestepping QuickBase and HighCharts features, you can change the the charts labels from "3" to "Three" using this JavaScript code:

$("tspan:contains(3)").filter(function(){ return $(this).text() === "3"; }).html("Three");

Depending on your workflow and needs you can (1) inject this code manually (see before / after screenshots), (2) through a CrossRider extension; or (3) through a script in a containing page that the chart inserted through an <iframe> resides in.
