splot with vectors vs. grid data

[<te...@me...>]

Hello,

Since latest stable release, I am using gnuplot routinly to visualize 2D
and 3D simulation data (also).

Now I am using the latest experimental version because the ability to plot
vectors on pm3d map. It works fine, although I have a suggestion to
make it more convenient.

currently if grid data is used (grid rows are separted with empty lines)
the following error message appears:

"Cannot plot multiple contours in style vectors"

So currently I am using different output file for vector and scalar
quantities.

Also "splot every 2:2" option cannot be used to each grid direction for
vector plot (obviously because it is not a grid data). It is an important
feature, because vector plot usually so dense that few things can be seen
if some rows and columns are not eliminated.


Thank you very much for your work on the best open source ploting tool,
and I hope my suggestions will be usefull in further developing the code.

Best Regards,
George Tegze
