[Plplot-general] PLplot grid

[Lukas <re...@ho...>]

I'm not sure whether or not this is the correct way to post a question on
the plplot-general mailing list. Is I do this wrong, can anyone tell me the
correct way?

 

My Question:

I'm new to PLplot. Previously I use GNUplot but then had problem with
plotting speed when plotting too many points. Anyway, can anyone tell me if
PLplot is the right tool to go? 
 
Criteria: 
- one window with 4 subplot. Top half plot ONE 3-D plot and bottom half has
THREE 2-D plots. 
- Plot 10,000 - 20,000 points (I don't need to plot surface or lines, just
points). 
- has to be fast (My program will keep on refreshing the plot). 
 
My next question is that I tried to create a 3D plot in PLplot, but I want
to have grids on the x-z and y-z plane, just like example 11 in PLplot
website: http://plplot.sourceforge.net/examples.php?demo=11. 
My Understanding is that I need to use add a letter 'd' inside the function
plbox3(..), but the grid will only be showed after we call either
plot3d(...) or plmesh(...). 

The thing is I only want to plot a point in the 3D plane so I only use
plpoin3(...). And no grid is showed. 

Do I miss something? Is there an easy way to plot grid? Is there another way
to get what I want? 
 
thanks so much for the help.
