I am new to QGIS.
I need to make a map that looks like a heatmap, but is based on data values, not point concentrations, and with a legend. I was able to make a heatmap based on data values, but not able to create a legend also based on the data values instead of the point concentrations.
I also tried making a raster map, but the map values seem to be based on point concentration instead of the data values.
How can I do this?
