What is the problem or goal you're trying to solve or accomplish?
When "Show Values" is enabled on the Calendar Heatmap chart, all cells in the calendar grid are labeled — including empty cells that have no data for that domain/subdomain combination. These empty cells display the text "null," which clutters the visualization and is confusing to end users. There is currently no way to show value labels only on cells that contain actual data while leaving empty cells blank.
How are you solving it currently?
There is no viable workaround. Metric-level SQL transformations (e.g., COALESCE, CASE WHEN) have no effect because the null labels are rendered at the chart layer, not driven by query results. The only available option is to disable "Show Values" entirely, which also removes the desired value labels from data cells — an unacceptable tradeoff for customers who need both.
What is your recommended solution?
Add a control to the Calendar Heatmap's Customize tab — such as a toggle labeled "Hide null cell labels" or "Show values on non-empty cells only" — that suppresses label rendering exclusively on cells with no data, while continuing to display value labels on cells that have actual metric values. The underlying chart library supports conditional label formatting, so this would require exposing that behavior through the chart's control panel.
