MATLAB: How to change figure properties

change figure properties

Hello,

I opened two figures and I gave them names. I would like to change their properties not directly after I created them but a posteriori.

Here is an example of what I try to do:

fig1 = figure;
plot(1:10,1:10,'r+');
fig2 = figure;
plot(1:10,-1:-1:-10,'b+');
set(fig1,'xlabel','position')

But I get the error "The name 'xlabel' is not an accessible property for an instance of class 'figure'."

What should I do to have it working?

Thanks

Guillaume

xlabel is a property of the axes, not the figure

(I assume that is enough for you to solve the problem, if not I can expand it!)

MATLAB: Figure visibility changes upon axes call

According to the axes help, the syntax axes(h) "makes existing axes h the current axes and brings the figure containing it into focus". I guess "into focus" includes being visible...

The help gives this example " to make an axes the current axes without changing the state of the parent figure", instead of

axes(axes_handle)

you should use

set(figure_handle,'CurrentAxes',axes_handle)

MATLAB: How to superimpose plots from 2 (.fig) files

Hello Francis,

You were on the right track, but you only made one subplot. I'm assuming, since you're using subplot, that you want two separate axes on the figure. Here's a quick example of how you can do it with copyobj:

% Setup the figures
hFig1 = figure;
plot(1:10)
hold on
plot(2:20)
hFig2 = figure;
plot(10:-1:1)
hold on
plot(1:10)
% Create new figure and copy over
hFigTarget = figure;
hAxTar1 = subplot(2, 1, 1, 'Parent', hFigTarget);
hAxTar2 = subplot(2, 1, 2, 'Parent', hFigTarget);
hAx1 = hFig1.Children; % Assuming there's just one child
hAx2 = hFig2.Children;
copyobj(hAx1.Children, hAxTar1)
copyobj(hAx2.Children, hAxTar2)

Another way to do it would be to just copy over both axes, and change their 'Position' or 'OuterPosition' properties to simulate what subplot does. I personally find that this works pretty well to simulate subplots:

hAx1.Units = 'normalized';
hAx1.OuterPosition = [0 0.5 1 0.5];
hAx2.Units = 'normalized';
hAx2.OuterPosition = [0 0 1 0.5];
