RE: subplot

[Neil.Francis]

Hello,

I'm a newbie to Octave, but (FWIW) on my Octave (Mac OS X fink binary
2.1.53, when
I try your code (followed by a "replot" at the end), and substituting

subplot(1,2,1); imagesc(data);

with 

subplot (1,2,1); plot(sin(4*x));

the subplotting seems to work fine.

The problem that I experience is that the imagesc doesn't seem to work.

Even without the subplots, if I use

data = rand(100,100);
imagesc(data);
replot;

I'm told "error: replot must have something to plot".

When I look at the source for imagesc.m I see it uses image.m, and
image.m appears
to not use gnuplot, but rather ImageMagick, xv or xloadimage.  Perhaps
our machines don't
have any of these installed, and they are needed?

Neil

Hi there,

Does any one know how to include imagesc in subplot as
Matlab?

In matlab, it is easy to combine image and graphs in
subplots. For example

data=rand(100,100);

x=0:0.1:pi*2;

subplot(1,2,1); imagesc(data);
subplot(1,2,2); plot(sin(x));

This will plot two figures together.

However, the above will not work in Octave.
