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)?
