#212 — Right margin in pm3d plot not correct when using cblabel and postscript terminal

Hello,

as you can see in the subject, I have problems plotting a cblabel at the 
right side of a pm3d plot when using postscript terminal. An example:

#####
set pm3d map
set cblabel '{/Symbol a} [Gy^{-1}]'
set terminal postscript eps enhanced 16 rounded color
set output 'Test.eps'
splot 'Data.dat' using 1:2:($3/100) w pm3d
unset output
system 'epstopdf Test.eps && rm Test.eps'
####

The file Data.dat contains:

10 10    1.10
10 100   0.23
10 1000  0.12

20 10    1.10
20 100   0.29
20 1000  0.16

Only "-1" is visible in the final pdf on the right side. 

The cblabel is correctly displayed if I change the splot command line to

splot 'Data.dat' using 1:2:($3/10) w pm3d

so that the tics on the cblabel are not so wide. Is this a bug or is there 
a way to automatically adjust the right margin of the plot? Setting 
rmargin does not seem to have any effect.

I'm using gnuplot version 4.4 patchlevel 2 (Gentoo revision r1) on a 
current stable gentoo.

Thanks in advance
Uwe Scholz

PS: By editing the bounding box in the eps file before converting it to 
pdf it is possible to see the whole cblabel. But this is only a 
workaround by now and no solution... :-|

Setting the rmargin works for the CVS version. Try with
set rmargin screen 0.8

Interestingly, the right margin is correct, if I use

set cbtics format '%.3f'

which gives you the same number of digits as the default format '%g'.

But I do not know, where this difference comes from. And, If you need 
even more digits, the margin is not correct again.

Nice to hear. Hopefully it will be stable some day :-) Nevertheless, the 
complete color box label should be visible without any margin tweaking, 
right? Does it show up correctly in the CVS version without doing so?

This moves the hole plot to the left, also the cblabel. Thanks! By 
adjusting lmargin, the plot looks as I want. This is of course only a 
workarount, but it's a shorter one than directly editing the eps-file.

Thanks for trying this. I can confirm this strange beaviour here.

Yes, it is a solution; thus use the following automation solution (as you 
should do for any eps figure to be included in another document):

system 'epstopdf Test.eps && fixbb Test.eps && rm Test.eps'

Great! This script works for me. How could I lived without it?

Though, the gnuplot line must be:
system 'fixbb Test.eps && epstopdf Test.eps && rm Test.eps'

Many thanks!
