[jCharts-users] Axis Label Grouping

[Uwe S. <uwe...@xa...>]

Hi,

I wonder if there's some way to combine axis labels into groups. I have a 
number of products for different countries which I need to compare, so a 
product can appear more than once in the chart (but each time for another 
country). Now I'd like to visualize the country groups like this:

|    x                x          x
|    x          x     x       x  x       x
| x  x  x    x  x  x  x    x  x  x   x   x  x
+---------------------------------------------
 P1 P2 P3 | P1 P2 P3 P4 | P1 P2 P3 | P1 P2 P3
  France  |   Germany   |    UK    |  Spain

The best I could come up with yet is coloring the bar backgrounds differently 
for each country, or splitting the chart into several charts. But both are 
unsatisfactory.
Is there any way to display this kind of grouping with axis label extensions 
like above? Or maybe comments inside the chart, centered above the appropriate 
bars?

I know I'm brutalizing the jCharts library here, sorry ;o)
