[ncl-talk] Bar Graph Overlap

[Rick Brownrigg]

Hi Zach,

I've studied this, and I am not sure what is going on.  I speculate that
since the xy plots are drawn independently, their x-axis are also
independent, but the positioning of the bars is at the same spot
*graphically* rather than in data-space. (make sense?)

Also, I'm confused by these settings:  tmXBValues = (/11,12,1,2,3/).
The docs for tmXBValues state the values should be monotonically
increase/decreasing (?)

Here is an example that looks like what I think you might be going for;
perhaps it will yield some insights:

Hope that helps...
