Hello,
I'm using plot command to plot some curves. I'm using XTICKNAME to
define my labels' names in the axis x.
My question is... Can I plot these labels in a vertical orientation??
I need to do that, because my label's names are too long.
Comments welcome,
Cheers!
Hervé

Thanks Tim, the code is fine!!
Best!

Hi there Hervé,
Here's how you could do it in an almost general fashion:
x = findgen(100)*1d19
y = sqrt(x)
charsize=2.0
; PLOT THE DATA, DON'T LABEL THE X AXIS AND RETURN THE XTICK VALUES...
plot, x, y, XTICKFORMAT='(A1)', XTICK_GET=xticks, YMARGIN=[9,2], $
CHARSIZE=charsize
; CONVERT THE XTICK VALUES TO NORMALIZED POSITION...
xtickpos = !x.s[0] + !x.s[1]*xticks
; GET THE CHARACTER HEIGHT AND WIDTH IN NORMALIZED COORDINATES...
y_ch_size = charsize * float(!d.y_ch_size) / !d.y_vsize
x_ch_size = charsize * float(!d.x_ch_size) / !d.x_vsize
; PUT THE LABELS AT THE APPROPRIATE TICK POSITIONS...
xyouts, xtickpos+0.5*x_ch_size, !y.window[0]-0.5*y_ch_size, /NORM,
xticks, $
ALIGN=1.0, ORIENTATION=90.0, CHARSIZE=charsize
It sounds like in your case you already have the value of xticks and
rather than retrieving xticks via XTICKS_GET, you'll probably be
specifying the tick values immediately using XTICKS and XTICKV. You
can change the ORIENTATION to 45 to save a little more room for the
plot.
Hope this helps! Best -Tim.
