Re: [Gnuplot-info] surface 3d plot

[Thomas S. <t.s...@fz...>]

translucency is a feature of the development version of gnuplot,
have a look at:

Re: [Gnuplot-info] Surface plot from data files

[Thomas S. <t.s...@fz...>]

you may set
gnuplot_binary ("tee logfilename | gnuplot")
at the octave prompt to see which commands are sent to gnuplot.

Re: [Gnuplot-info] surface 3d plot

[Thomas S. <t.s...@fz...>]

you may plot the surface with the 4th 'using' argument specifying
the color in 'pm3d' mode.
but this color information has to be calculated elsewhere, 'gnuplot'
isn't a ray-tracing program.

you are looking at a 2-dim projection of a 3-dim object.
in this projection everything is flat.

a 3-dim tube is reduced to a flat strip in the 2-dim projection - that's
what
you see.
and because the projected line has the same thickness under all viewing
angles, it's the 2-dim projection of a 3-dim tube.
if it would be flat in 3-dim you would be able to select a viewing angle
under
which you could look at the line 'from the side', i.e. the line thickness
would
reduce to 1 pixel. obviously, you can't do that.

[Gnuplot-info] surface 3d plot

[cédric o. <ced...@gm...>]

Hello,

I would like to plot a surface (x,y,z) with a uniform color but also with
light/shadow effects. Also, it is possible to add translucidency as in other
softwares.

I have seen a trick to lighten locally the surface but it does not
correspond exactly to what I would like.

Thanks for any help,

Cédric

Re: [Gnuplot-info] Surface plot from data files

[drgz <sy...@ho...>]

Yup, I found those help commands later on last night, but I still get plots
that look much "uglier" than the ones from the surf(). Maybe it would be
better I found out what commands octave calls in Gnuplot when the surf()
function is called, but when i open surf.m / surface.m I can't find any
useful information.


Basically I would like to know how to get the same plot as in th the example
PDF, but from scratch in Gnuplot, such that I easily can change whatever I
want to change.

Regards,

drgz

[Gnuplot-info] axes through origin

[WesM <wes...@gm...>]

Hi again

How does one set the axes in an splot so that all axes pass through the
origin
rather than where autoscale puts them?

Thanks!

[Gnuplot-info] linewidth in splots

[WesM <wes...@gm...>]

Hi again

When I increase the linewidth in an splot the line gets wider in one
dimension only so
that what started as line before increasing the linewidth looks like a plane
after increasing
the linewidth. Is there a linestyle change (or any other method) that will
allow me to make 
the thicker line look like a beam instead of a plane (ie linewidth increase
in 2 dimensions)?

Re: [Gnuplot-info] Using multiplot with splot

[Thomas S. <t.s...@fz...>]

then you should follow the suggestion of "Hans-Bernhard Bröker-2":

> splot 'data1', 'data2'

and not use 'multiplot' mode.

Thanks again Thomas

That works except that when I try to rotate the image using my mouse the

[Gnuplot-info] u3d

[micmac <jul...@da...>]

let me dream,,,
is there a terminal for gnuplot which can export in .u3d ?

that would be so cool!

That's usually not the right approach.  You can just plot two surfaces 
in one plot:

	splot 'data1', 'data2'

Re: [Gnuplot-info] Using multiplot with splot

[Thomas S. <t.s...@fz...>]

use
set xrange [] writeback
set yrange [] writeback
set zrange [] writeback
and
set xrange restore
set yrange restore
set zrange restore

Re: [Gnuplot-info] lines in 3D

[Thomas S. <t.s...@fz...>]

you may plot vectors:

set xrange [0:pi]
set yrange [0:pi]
set zrange [0:1]
set surface
set hidden3d

splot sin(x)*sin(y), '-' with vectors nohead
0.5 0.5 0.5 2.0 0.0 0.0
2.5 0.5 0.5 0.0 2.0 0.0
2.5 2.5 0.5 -2.0 0.0 0.0 
0.5 2.5 0.5 0.0 -2.0 0.0

[WesM <wes...@gm...>]

Thanks again Thomas

Can the arrow command read its head and tail coordinates from a file? If so
would you show me
how to do that.

[Gnuplot-info] Surface plot from data files

[drgz <sy...@ho...>]

Hello,

I'm trying to make a surface plot using data I've exported from Octave. I
found it to be easier to edit the labels etc with Gnuplot when I did my 2D
plots, so I want to do the same with the 3D plots, but I simply don't get
how to organize the data such that the plot becomes the same as when using
surf() in Octave.

Example;

I got two vectors and a matrix I want to plot:

size(freqvec) = 101 x 1
size(pinvec) = 26 x 1
size(s22vec) = 101 x 26

Should I save these to three separate data files, or should I save them all
to the same file? And how is the syntax for linking them together in
Gnuplot?

I've tried both saving them to different files, and to the same file, but I
simply don't manage to get it right.

When using Octave, I get the plot as in the attached file, which is nice,
but as I want to tweak a little on the figure I thought it might be easier
doing it from Gnuplot directly.

So can anyone point me in the right direction, or know somewhere I can read
about how to get the plot right?

Best regards,

drgz

[Gnuplot-info] Using multiplot with splot

[WesM <wes...@gm...>]

Hi

I am using multiplot mode to plot two surfaces on a single plot. The problem
I am having 
is that each plot uses a different origin and ranges. I would like the
second plot to use
the ranges and origin of the first plot which are computed by autoscale. How
can I do this?

Thank you Thomas. That will work.

Re: [Gnuplot-info] lines in 3D

[Thomas S. <t.s...@fz...>]

you may add arrows without heads:

set xrange [0:pi]
set yrange [0:pi]
set samples 10
set arrow 1 from 0.5,0.5,0.5 to 2.5,0.5,0.5 nohead front
set arrow 2 from 2.5,0.5,0.5 to 2.5,2.5,0.5 nohead front
set arrow 3 from 2.5,2.5,0.5 to 0.5,2.5,0.5 nohead
set arrow 4 from 0.5,2.5,0.5 to 0.5,0.5,0.5 nohead
splot sin(x)*sin(y) with pm3d
