The GIF images that appear below were created in the following
way. The switch plotopt("-colorps") was used. Each plot was first
created as a PostScript file by pressing the "Print to File" button in
The PS file was read in XV program and the background and line colors
were edited. The figure was then saved as GIF from XV. The quality of
the GIF images is lowered to save network bandwidth.
Contour plot with annotated points
is part of the standard Tela demos. The basic contour plot has been augmented
with some labelled red dots and green circles.
Pseudocolor plot of turbulent spectrum
is also part of the standard Tela demos. It presents the basic pcolor command.
The plot represents a quick and dirty way to simulate a "turbulent" spatial spectrum:
Compute the intensity with random phases and power-law k-dependence in k space and
transform it to real space using the inverse Fourier transform.
Mesh plot example. The following commands were used
to generate this picture:
r = sqrt(x^2 + y^2);
