Re: EDM xyGraphClass yLabel displaying backwards

[John Sinclair <sinclairjw@ornl.gov>]

Carl,

At some time in the past, an individual made some nice changes to the XY 
graph and added the feature you describe. The problem is
that this makes things display properly for non-scalable fonts (which 
don't get rotated). So previously, the scalable fonts displayed
properly and the non-scalable ones did not. Now, the reverse is true. I 
guess I can change it back and add a check-box to indicate the
desired direction.
