Hi David et al,
It seems that cgBoxPlot is not responding to the xCharsize keyword. I tried the code below:
PS_Start, 'cgHistoplot.png'
!P.Multi=[0,3,1]
labels=['var1','var2','var3','var4']
cgdisplay, 1000, 300
cgBoxPlot, randomn(seed, 4, 1000), labels=labels
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, xCharsize=0.5
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, xCharsize=0.25
PS_End, resize=100, /png
the results looks like:
https://lh6.googleusercontent.com/-ppRoZheCmwk/UdJ-laUulrI/A AAAAAAAipg/LBKMp-QCcJE/w1358-h406-no/cgHistoplot.png
I've just updated the library to make sure I'm using the latest version.
IDL version: 8.2.0 on Windows
cheers

Yes, I was using the XCharsize value incorrectly in this program. You
can find an updated version here:

Unfortunately, this is not going to solve all your problems. :-)
The larger problem here is doing multiple plots with !P.Multi. This
method of doing multiple plots is great as long as you are willing to
surrender all control over plot position and character size and rely
completely on the !P.Multi algorithm to set these for you. But, if you
wish to control this aspect of your plots (as I do in cgBoxPlot), then
chaos is certain to ensue.
In this particular case, since I am putting plot labels on with XYOutS,
there will be a terrible mismatch between the size of the plot
annotation, which is under the influence of !P.Multi, and the plot
labels, which are not. Basically, you will never be able to get the two
sizes to match! (Or, if you do, immediately call me with the algorithm
you used!)
Download the updated program, then consider this code. Here is how you
are doing things now.
!P.Multi=[0,3,1]
labels=['var1','var2','var3','var4']
cgdisplay, 1000, 300, wid=1
cgBoxPlot, randomn(seed, 4, 1000), labels=labels
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, xCharsize=0.75
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, xCharsize=1.25
!P.multi=0
You can see the plot annotations are all over the map!
In this case, it will make a LOT more sense to use cgLayout to set up
your plot positions, which will allow you to control your plot
annotations exactly. There will be no interference from !P.Multi.
See how much more sense this way of drawing the plots makes.
positions = cgLayout([3,1], xGap=5, oxMargin=[5,5], $
oyMargin=[5,3])
labels=['var1','var2','var3','var4']
cgdisplay, 1000, 300
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, $
Position=positions[*,0]
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, $
Position=positions[*,1], /NoErase, XCharsize=0.75, $
Charsize=0.75
cgBoxPlot, randomn(seed, 4, 1000), labels=labels, $
Position=positions[*,2], /NoErase, XCharsize=1.25, $
Charsize=1.25
Cheers,
David

Thanks David, will try with the updated version.
RE !P.Multi, your explanation is useful as I have already noticed some funny things happening with fonts in some of your programs.
cheers
