Heatmap "hide cells" not stored

Grafana Dashboards

Grafana v10.2.6

I’m creating a heatmap of RSSI for devices connected to my WiFi. RSSI values are negative. Nothing is displayed when this field is left to the default value 1e-9.

If i remove it, the graph displays as expected.

When I save, exit the page and reload - the 1e-9 is back and the heatmap is empty again.
I have tried to duplicate the graph, recreate it, modify but the issue persists.

Try edit/save json model (of the panel/dashboard) directly.

Creative proposal @jangaraj, but unfortunately the filter pops back after a reload with your method as well.

@eriktar Hi, not sure if it’s still actual, but for me -1 did the trick to show 0s and being saved after page reload. Perhaps -1000 or something like that will help in your case.
