Dear Mr Mikulik, 

#]> 1) when I use identical data and an identical macro for "with pm3d" and
#]> "with image" (postscript terminal), the image is drawn much too big and
#]> covers the lower plot border. do you have any idea how to fix this?
#]> (for examples see above url)
#]
#]In pm3d, you can use "set pm3d clip..." settings.

I'm sorry, I have not expressed myself clearly enough... everything is 
working perfectly with pm3d mode. 

Its just that when I use the same parameters for "with image" mode
instead, then the color plot is scaled incorrectly and does not fit into
the "axes frame".

#]> 2) is there any way to set the "missing data" color for "with image" (and
#]> perhaps "with pm3d") ?
(...)
#]
#]For pm3d, either miss them in the data file, or set a z-range, or use
#]different z-range and cb-range;
#]	set zrange [10:1e8]
#]will invalidate all data out of the above range.

Do I understand this correctly that in pm3d map mode the zrange controls 
whether points are "drawn", i.e. whether for example in a postscript image 
the background is visible or not?

#]That cannot be done for "with image" for principal reasons -- that's to draw
#]a matrix, so all pts must be valid. Thus, you have to make a palette with
#]one color white and use the corresponding value for coloring your special
#]pixels.

Sure... what I was asking is: is there any way to set this special color
value?

regards, Andreas
