Figure vs axis handles?

David Doria — Thu, 10 Apr 2008 14:26:31 -0400

f=figure;
BottomLeftPlot = subplot('Position', [.05 .1 .4 .4]);

I can set some properties like this:
xlim(BottomLeftPlot, [-180 180]);

and some like this:
set(BottomLeftPlot, 'XLimMode', 'manual');

but some dont work at all?
set(BottomLeftPlot, 'YLabel', 'beta');

Is there a good tutorial somewhere about which properties
belong to the figure, which belong to the axis (or is it
axEs?) and how to set them?

Thanks!

Dave

Yes, if you open the help browser and look under "Handle Graphics
Property Browser". Hope it helps.

Thanks, thats really helpful - here is the solution to my
problem:

doesn't work:
set(BottomLeftPlot, 'Title', 'OnCircle');

works fine:
set(BottomLeftPlot, 'Title', text('String','OnCircle'));

it seems matlab should be able to recognize that 'OnCircle'
should be treated as a text string... but apparently it can't.

Go to help page and type "axes properties" in the search
box, in the description of "title" property, the help file
states that the value must be a handle, and not a string.

text('String','OnCircle') returns a handles.

Correct. The Title property of an axes stores the handle to a text object,
and that text object stores the string that is displayed as the title. You
could use the method you described above, or you could use:

set(get(BottomLeftPlot, 'Title'), 'String', 'OnCircle')

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/axes_props.html#Title

Or, of course, you could use the TITLE function, which accepts as one of its
inputs a handle to the axes whose title you want to set or change. If
you're going to be modifying the title frequently, you can also return the
title text object's handle from TITLE and use SET on it directly later on.
