Scatter polar plot in matlab
Mike Nelson
I'm trying to do a wedge plot (right ascension vs redshift). I was thinking I could use a scatter plot in polar coordinates. The polar function in matlab seems very limited. Even this
polar(a(:,1),a(:,2),'Linewidth',1)
gives me an error:
Error using polar (line 23)
Too many input arguments.
Is there a simple way to achieve what I want using Matlab? Do you know of another software that would do it easily?
Thanks,
Mike

Matlab is quite adequate for that, I think.
As for the polar function, it seems it doesn't allow properties (such as 'linewidth') to be specified directly. But you can get a handle to the created object and then set its 'linewidth', or other properties:
h = polar(a(:,1),a(:,2));
set(h,'linewidth',1)
If you want a scatter plot, maybe you'd prefer not to have lines, but instead to plot a marker (such as a dot) at each point:
h = polar(a(:,1),a(:,2),'.');
set(h,'markersize',12)
Example:
To see a list of properties that you can set, as well as their current values, type
get(h)
