max # of data points?

[rly...@my-deja.com]

Hi,

I am trying to create a contour plot where x
should be plotted from 0 to 1.5 and y should be
plotted from 0 to 1. I have 10280 data points
(listed as xyz triples) in my data file. When I
plot this data, I get only a plot of x ranging
from 0 to 1 rather than 0 to 1.5. Could I have
too many data points and gnuplot is reaching the
maximum and quitting? I haven't set the range of
x to be 0 to 1, actually, I have set the range to
be 1 to 1.5. FYI, the commands that I am using
are listed below.

set terminal postscript
set output 'contfs.25.ps'
set nohidden3d
set parametric
set dgrid3d 128,80,2
set data style lines
set view 0,0
set contour
set nosurface
splot [0:1.5][0:1] 'vp25.dat'

Hi,
I am using gnuplot to create a contour plot. When I use a grid size of
32 x 20, I am able to create the plot to what I am expecting. When I
double it in each coordinate direction to 64 x 40, I have 4 times as
many data points and the x axis is only plotted from 0 to 1 where it
should be 0 to 1.577. Another way of saying it is that at the larger
number of grid points, the plot is not complete. I have tried to
specify a domain in the plot statement that encompases the domain in
which I am interested. Is there a maximum number of data points that
gnuplot can handle? If this isn't the problem, what can I do to fix it?
FYI, these are the commands that I am using...

set terminal postscript
set output 'contfs25.ps'
set nohidden3d
set parametric
set dgrid3d 64,40,4

set data style lines
set view 0,0
set contour
set nosurface

splot [0:2][0,1]'vp25.dat'

Thanks. Also, if it's no problem, please respond to

Depending on what version of gnuplot you have, that may be the case.
The current version, 3.7, has almost all the fixed limits removed,
replacing them by the rule that you cannot use more memory than your
machine offers.
