plot perspective

[William E. <mru...@po...>]

Hi Guys,

  How can I make gnuplot produce a 3D plot with true prespective.  By 
that I mean that X, Y and Z
all relate to each other.  The scale of X, Y and Z are the same.  A 
picture is worth more that me
explaining.

  This is what gnuplot produced:

  If I expand the image wide, I get what look better:

    http://mt-umunhum-wireless.net/Images/Gnuplot_2.png

  What I want is for gunplot to produce the second image with the right 
perspective.

  Thanks for you time.

    I am not sure what you mean. If you simply want to change the aspect
ratio of the plot, you should have a look at the "help size"
documentation page. If you are looking for a true perspective view
(parallel lines meet at the horizon), then this is not currently
implemented. We are working on enhancing the 3D engine of Gnuplot so
this might happen one day, but currently the work isn't happening very
quickly.

Actually, there is a patch at SourceForge doing exactly that.  But I
don't think this is what the OP asked for.
