Thanks.

Well, when I specify which column shall go to the x-coordinate and which
column contains y-coodinates, there shall be no room for
misunderstanding that.  "using x:y:cb" is umambiguous, isn't it?  The
only workaround I see is sticking with 5.0.3 until this is fixed.

I understand that the image plots may have a hard time to figure out
the binning of the data.  That is why my scripts produce very
unambiguous data files:

x1 y1 z11
x2 y1 z12
x3 y1 z13
x4 y1 0

x1 y2 z21
x2 y2 z22
x3 y2 z23
x4 y2 0

x1 y3 z31
x2 y3 z32
x3 y3 z33
x4 y3 0

x1 y4 0
x2 y4 0
x3 y4 0
x4 y4 0

These worked fine since the early days of "pm3d corners2color c1".
If the new image parser misunderstands these files it is very broken.

I do not see how a transpose option is needed with this kind of
datafile.  As long as it is needed something is broken.  Matrix type
data may be a different issue, I never used that, yet.

And why did the PDF output filesize blow up out of proportion with 5.1
compared to 5.0.3?

Cheers,
