ufff.. de fun part of the exercise make me think that maybe is better to make the plot in excel!
Thanks David!

To do this, you will have to alter the cgBarPlot code to
suppress the labeling of the axis. Then add your own
axis labels with cgText. You can see how this is done
by looking at the code in cgDCBar, where this is done
with discrete color bars. Getting the spacing right
as you rotate the text is the fun part of this
programming exercise. :-)
Cheers,
David
