I want to create a legend like in the image attached.
The values in the first column (Molid;Brad;..etc) and in the first row (1-40; 41-80,>80) are values in two separate attributes fields of the same polygon shape.
How can I customize legend style to obtain a legend like the picture?
I tried, in shape's symbology, to create symbols using Categories-Unique values, many fields, but it is this far that I could imagine.
Thanks in advance for your attention.
