[Gnuplot-info] Plotting heatmap + "warning: Number of pixels cannot be factored..." + data file seems correct (I.E. K*N matrix)

[julien.siebert <jul...@gm...>]

Dear all,

I am having trouble while plotting some heatmaps with the following
commands:

"set view map
splot 'myfile' matrix with image"

Where myfile is an ASCII file containing N lines and each lines containing K
floating point values.

It worked really well until I have the following error:
"warning: Number of pixels cannot be factored into integers matching grid. N
= 500500  K = 2000"

I understand the error, Gnuplot told me that it cannot read "myfile" as a
500500*2000 grid.
The problem is that "myfile" is actually 500500*500 grid. (really I check).

It seems to me that gnuplot is having trouble while determining K.
I don't know if it comes from the fact that I am using floating point values
(As I said it worked well before)?
I don't know if I can set these two values N and K by myself ?

Any idea?
Thanks,
Julien
