Dear All,
I have created a nice-looking plot with a color bar on the top but the
labels extend too far past the end of the bar. My plot is positioned
in the bottom 80% of the window and the color bar is in the top 20%
(using the POSITION keywords). The array of values I give to the
COLORBAR procedure extends beyond the end of the bar.
Here is a diagram of what happens:
1 2 3 4 5 6 7 8 9 0 <-labels
---------------------
--------------------- <-colorbar
____________
| |
| | <-plot
| |
|___________ |
Here is my code:
PLOT, FINDGEN(10), POSITION=[0.05, 0.05, 0.95, 0.82]
ticks = (SINDGEN((clrTableLength/5)+1)*5)-(clrTableLength/2)
COLORBAR, BOTTOM=0, NCOLORS=clrTableLength, /TOP, $
TICKNAMES=ticks, COLOR=black, DIVISIONS=(clrTableLength/5), $
POSITION=[0.07, 0.87, 0.93, 0.95]
'clrTableLength' is the length of a color table I created. Currently
I am using a table of length 100 (i.e. clrTableLength=100)
Thanks,
Ryan.
P.S. David Fanning if you are reading this, I cannot access your web
page to see if you have any documentation on this at the moment
because all external network connections are down except internal
pages and any Google affiliated pages. (Please don't ask me why this
is, I don't know)

OK, so if anyone's interested, I've got a little workaround.
Basically, it's slightly mod-ing of colorbar so that it works (I'm
doing a vertical bar, with /right set)- the keyword I was looking for
is [xyz]tick_get:
PLOT,[minrange,maxrange], [minrange,maxrange], /NODATA,
XTICKS=1, $
YTICKS=divisions, XSTYLE=1, YSTYLE=1, $
POSITION=position, COLOR=color, CHARSIZE=charsize, /NOERASE,
$
YTICKFORMAT='(A1)', XTICKFORMAT='(A1)', YTICKLEN=ticklen , $
YRANGE=[minrange, maxrange], FONT=font, _EXTRA=extra,
YMINOR=minor, ytick_get=Y_tick_values
mid = FINDGEN(divisions)
FOR i=0, N_ELEMENTS(y_tick_values)-2 DO BEGIN
mid[i] = (y_tick_values[i]+y_tick_values[i+1])/2
ENDFOR
AXIS, YAXIS=1, YTICKV=mid, $
YTICKFORMAT=format, YTICKS=divisions, $
YTICKLEN=ticklen, YSTYLE=1, COLOR=color, CHARSIZE=charsize,
$
FONT=font, YTITLE=title, _EXTRA=extra, YMINOR=minor,
YTICKNAME=ticknames

Thought (afraid?) that was going to be case. Thanks!

The COLORBAR program, for historical reasons, as well as for
ease of programming, uses a PLOT command to do the annotation.
So, what you want to do is not possible with that code.
And because of recent changes, I can't even offer an undocumented
keyword solution that will completely scrub the bar of annotations,
so you could write your own axis labeling routine. :-(
I'd recommend just writing your own colorbar routine. You can use
PLOTS to draw your boxes on the colorbar image, and you can annotate it
however you like with XYOUTS.
Cheers,
David
