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.
