At this time, the Chart component in Glide doesn’t support selecting computed columns from Glide Big Table as data sources for chart values. This is due to the way computed columns in Big Table are processed, which isn’t currently compatible with the Chart component.

If you’re looking to visualize data from Glide Big Table, there are a couple of workarounds. One option is to use a basic column in Glide Big Table for your chart values, which should allow the Chart component to display data as intended. Alternatively, you can use computed columns within a regular Glide Table, which work seamlessly with charts. We recommend choosing one of these options until computed columns from Glide Big Table become supported for Chart visualization.
