I need to obtain a bubble chart of categorized data, similar to this one:
My data looks like:
forType_label reg_label forType_n reg_n area
broadleaves AL 1 1 20
broadleaves AU 1 2 15
broadleaves PA 1 3 30
coniferous AL 2 1 7
coniferous AU 2 2 6
coniferous PA 2 3 9
I managed to get the bubble chart and, setting manually the chart axis options, to shown only integer numbers, but how can I shown labels (forType labels and reg labels)?
