#4197 — set view or rotate

I have this plot: http://dieterbritz.dk/sdr1.pdf

generated in gnuplot simply with

splot '2D.dat' w l

I would like to change the angle of view so that I am 
looking directly at what is now the far right-hand corner,
making it the far left-hand corner. This corresponds to a
rotation of the XY plane by 90 degrees anticlockwise.

I have tried adding "rotate=0.5pi" to the splot command, and
various set view combinations, but nothing changes the plot.

How can I do it please?

Hi

I can't see the picture, but I'm not too sure it can be done. I crass work around might to plot it with negative x coordinates 

splot '2D.dat' u (-$1):2:3 w l 

And the you can play around with the xtics to make the negative go away from the display 

set xtics ("0" 0, "50" -50, "100" -100)

As I said, this might be too crass of a solution and others might have something more elegant.

Best


Gavin

You can use an interactive terminal, rotate the view with the mouse,
and afterwards check what options "show view" displays, or "save
'2D.plt'" writes to disk.

Btw. splot has not "rotate" option, and "set view" expects angles in
degrees, not radians.

Thanks. If I want to rotate as I described, what do I put
into set view?

I fiddled with it and worked it out, thanks.
