Thread Subject: setting axes color

Dear all,

I m drawing a polar plot and want to set the figure color to
red and axes color to black, for that i m using following
commands,

figure;
polar(100,200,'*');
set(gcf,'Color','r');
set(gca,'Color','b');

In this the gcf command is working and gca is not working..
Is there any way to change the polar axes color to black.

The above commands are holds good for all the graphs which
can be drawn from plot command. But not for polar plot ..

Regards,
Ashwini

Hi Ashwini,

polar.m draws a circular patch object on the axis using
Matlabs default axes color:

% --- from polar.m --- %
% plot background if necessary
    if ~ischar(get(cax,'color')),
       patch('xdata',xunit*rmax,'ydata',yunit*rmax, ...
             'edgecolor',tc,'facecolor',get(cax,'color'),...
             'handlevisibility','off','parent',cax);
    end

So even if you change the axis color, it is not visible
through the patch. Use the following code to change the
color of the patch object to the color of the axes:

polar(100,200,'*');
set(gcf,'Color','r');
set(gca,'Color','y');

set(0,'ShowHiddenHandles','on');
ch = get(gca,'Children');
chType = get(ch,'type');
isPatch = strcmp('patch',chType);
set(ch(isPatch),'facecolor',get(gca,'color'));
set(0,'ShowHiddenHandles','off');
