The performance grid allows you to compare the results of your users' performance snapshots against metrics such as tenure, custom fields, or other snapshot results.
Snapshot question themes were introduced along with the performance grid to make it easier to configure and get more value from the data visualisation. To start using the performance grid for the first time, you're required to link your snapshot questions to a question theme.
Please check if your performance questions are linked to a theme already by navigating to Studio > Snapshots > Questions tab.
If your snapshots questions aren't linked to a theme yet, you can link them yourself by editing the questions, or contact your success manager if you need help with this.
The tutorials below assume that your snapshot questions have been linked to a theme already.
