I am creating simple 2D heatmaps using the Python API. For some of my fields, I don’t have any data. This is OK and expected, but I would like to be able to mark these fields in the heatmap, for example by making those fields grey or black or any other easily recognizable color without affecting the rest of the color spectrum.
Currently, I just insert “-1” into those fields because my real data is always >=0, but of course plotly just interprets -1 as a regular value and thus just colors those fields blue.
Is there a way to insert “special” values into the heatmap for fields that should not be colored within the normal heatmap color spectrum? Or do you have another tip for how I could visually mark those fields?
