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 supports these same fields from the [Survey Add-on](https://www.gravityforms.com/add-ons/survey/), [Quiz Add-on](https://www.gravityforms.com/add-ons/quiz/) (Scores are not supported), and [Polls Add-on](https://www.gravityforms.com/add-ons/polls/).

Only one field can be used at this moment to generate a chart. You can create multiple charts for the same form by creating multiple feeds (1 feed = 1 chart).

*⚠️Multiple Rows Likert Survey fields and the Survey Rank field type are currently not supported*

## Number fields

Number fields are supported but they must be aggregated under a date field when "Show on Timeline" is selected as the Data Type:
