Type of Fields Allowed as Data Source on a Chart
In GravityCharts, only certain types of fields are allowed to be used as the data source for a chart.
These fields all have one thing in common, they allow for choices: Drop Down, Multi-Select Drop Down, Radio Buttons, and Checkboxes.
Our charts add-on also support these same fields from the Survey add-on.
Only one field can be used at this moment to generate a chart.
