Dear gnuplot users,

I am experiencing a problem with Gnuplot (Version 4.4, patchlevel 3) when I plot with dgrid3d option.
I tried the example from the demo script with the "Valley of the Gnu" and it works perfectly. As soon as I modify a little bit the "Valley", it's impossible for me to get a correct 3d mapping.

I am using these commands:
--

set dgrid3d 30,30 gauss 1
 
splot "dat.dat" u 1:2:3 w l
--

with this file dat.dat:
--
50 100 150 
50 300 210 
50 500 250

60 100 180 
60 300 210 
60 500 220

80 100 160
80 300 220
80 500 230
--

result:
https://drive.google.com/file/d/0BwZs38kg9uJUZi0xcEx5RnQ4eUU/edit?usp=sharing

Could you help me?
Thanks!
Johnny

The dx is given in units of the axes and 1 seems to be far too small. I 
don't know why this leads to missing lines, but choosen e.g. 50 works fine:

set dgrid3d 30,30 gauss 50
splot "dat.dat" u 1:2:3 w l
