[Gnuplot-info] plotting binary general array versus record

[Ian M. <ibm...@gm...>]

Hi,

I've got a 2D histogram in binary format (floats) which I'd like to plot
as a surface in 3D using splot.  So far I'm doing:
splot 'corr_990136_frameavg_MR.img' binary format="%float"
record=200x200 dx=1e-1  u (log($1)) w pm3d

(I'm not particularly attached to the log, but I notice that I do at
least need 'u 1')

This gives me roughly what I want (as attached), but I'd like the
ticks (x and y) to be in different units, which is where it gets
tricky.  As far as I can see I should use array=200x200 instead
of record=200x200 and then set the dx and dy I want, except
that doing this causes gnuplot to display the data as values on
a plane (I can still see it because of the pm3d display).

So what can I do to either get record=200x200 to use the grid
spacing I want or array=200x200 to take the z values from the
datafile?

Thanks for your time.
