Re: [Gnuplot-py-users] Notice: Cannot contour non grid data. Please use "set dgrid3d"

[Johannes R. <jo...@si...>]

Hi again,

By looking at the temporary files that Gnuplot.py generates, I finally
found out why I keep getting this warning. It is caused by the fact that
there is two newline characters at the end of these temporary files. I
removed one of the newlines and the warning was gone. To do this, simply
comment out the last line in the function write_array in utils.py:

-        f.write(nest_suffix)
+        #f.write(nest_suffix)

Hopefully, this will be fixed in the next release of Gnuploy.py.

Johannes
