CPBarPlot Width/Spacing

I am modifying the width of bars in a graph by using (CPBarPlot *)barPlot.barWidth, but the spacing between bars does not change and they now ov开发者_运维问答erlap each other. barPlot.barOffset works great for the initial offset, but I haven't been able to figure out how to change the spacing between subsequent bars. It seems like I have to change something with the spacing of intervals on the axis, but I don't see anything related to interval spacing in CPBarPlot. Anyone know how this can be accomplished?

Here's a post that might help out with this issue: http://mela.ertale.com/blog/?p=193

Good luck!
