Hey there,
This may be an oft asked question but is there any way to rotate tick labels in direct
graphics? I looked at the online help for all the various [xyz]tick... keywords, but
nowhere was rotation mentioned (that I could see at least). I saw that the capability is
available in OG which is not an option here (I just want to make a "quick" plot).
thanks for any info,
paulv

I would have preferred EASY, of course... but, I'll take anything that
works. Thanks, that did do the trick. I was doing something similar, but I
wasn't 'shrinking' the plot area on the page, so that when I tried to create
the labels using XYOUTS, I must have been outside the 'writable' area.
Thanks, David, I appreciate the fast help.

I have a short section in my book about how this can be done.
I was going to take it out of the 2nd Edition because I was
trying to save pages and I thought "who would ever need to
know how to do this?". But at the last minute I left it in.
You never know. :-)
Anyway, if you mean by "easy" some kind of keyword switch,
then the answer is "no". But is is not too hard either.
Suppose you are going to have 5 tick intervals, labeled
with 6 tick labels on the X axis:
numticks = 5
labels = ['One', 'Two', 'Three', 'Four', 'Five', 'Six']
Draw the plot, leaving some room for the rotated labels:
Plot, findgen(11), XTickFormat='(A1)', XStyle=1, $
XTicks=numticks, Position=[0.1, 0.2, 0.85, 0.95]
Calculate positions for the labels:
ypos = Replicate(!Y.Window[0] - 0.04, numticks+1)
xpos = !X.Window[0] + (!X.Window[1] - !X.Window[0]) * $
Findgen(numticks + 1) / numticks
Position the labels:
FOR j=0, numticks DO XYOutS, xpos[j], ypos[j], $
labels[j], Alignment=0.0, Orientation=-45, /Normal
Cheers,
David
