suggestion on axis ratios

[Georg <geo...@gm...>]

Dear Gnuplot Team !

I strongly appreciate your work and I got a suggestion for a (in my
mind important) feature.
I am working on grids for solving partial differential equations and
I have to check wether the grid lines are orthogonal to each other.

But orthogonal grid lines look distorted when the aspect ratio of the
section (related to the both axis) is not equal to one.
For example a section which shows eg. 10 units in x and 5 in y
direction.
The 'set size square' command only affects the lenght of the axis 'on
the paper' but not in reality. Tics and axis lenghts have to be
combined somehow.

Maybe there is already something in work or does even exist.
I do offer  my help! I hope the problem became clear at least.

Please answer me.


My best regards,

Either you don't ever read documentation, or you must be using an 
ancient version of gnuplot.  At least that's the only way I can imagine 
how you managed to find 'set size', with what you really wanted to do in 
mind, and not stumble across the solution:

	set size ratio -1

It would be nice if this worked for splot too.

It does, to some extent.  It's not perfect, but then, almost none of the 
3D plot layout really is.
