# ListContourPlot memory problems?

I have a simple 3d dataset (size 7035 x 3, I put it on my site if you want to check) which I want to plot with ListContourPlot:

x = Import["http://www.inrim.it/~magni/a.dat"];
ListContourPlot[x, PlotRange -> {All, {0, 6}}]


... and so far so good. But the x scale must - for various reasons - be rescaled, so I did this:

ListContourPlot[x /. {H_, f_, s_} -> {H*80, f, s}, PlotRange -> {All, {0, 6}}]


and M is unable to complete: after some seconds it exits without errors, and I discover the kernel has quit!

Same. Very strange. –  b.gatessucks Apr 1 '14 at 12:29
Kernel crash reproduced in Dell Latitude E6520 2.4GHz 8Gb RAM, Windows 7 SP1 64 bit, Mathematica 9.0.1.0. –  rhermans Apr 1 '14 at 12:36
Try using the option Method -> {"DelaunayDomainScaling" -> True} (see this) –  Simon Woods Apr 1 '14 at 12:56
thank you Simon, that worked - though it's really slow compared with the unscaled plot. BTW, I'm on v9.0.1, Linux –  alessandro Apr 1 '14 at 13:06
No problem on WinXP V9.0.1.0 –  Kuba Apr 1 '14 at 13:39
