MATLAB: Plot in predesigned figure

#predesigned plot

Hello

I have a script, where I tell my programm to create a figure, called h ,looking like the second picture.

then in a function within the scirpt (1. picture) i want matlab to draw my desired plot into the predesigned figure h. (See function in 4. picture)

but instead, matlab doesnt draw my plot into h, matlab draws it as in the 3. picture.

How do i plot into my predesigned figure h?

Thanks for the help!

You can assign a handle to the axes of the figure, and reference them in your plot function.

for example:

fig1 = figure;
a = axes;
fig2 = figure;
a2 = axes;
%plot in axes in fig1:
plot(a,1:5,1:5)
%plot in axes in fig 2
plot(a2,1:5,1:5)

Perhaps use hold on?

h=figure(1);
hold on
f_vorlage(h)
tryyy(h)

In addition in your tryyy.m have it grab the current plot handle with gca

function tryyy(fig)
h=gca
ax = findobj(h, 'type', 'axes');
if isempty(ax)
    error('Your figure does not have any existing axes')
end
if length(ax) > 1
    error('Your figure has more than one axes')
end
x=[52.23;52.45;56.32;55.48;56.32;53.39;55.53;53.67;57.89]
x=x'
plot(x)

Using a random set of values it looks like it plots properly

function tryyy(fig)
h=gca
ax = findobj(h, 'type', 'axes');
if isempty(ax)
    error('Your figure does not have any existing axes')
end
if length(ax) > 1
    error('Your figure has more than one axes')
end
x=200*rand(1,10000)-50;
plot(x)

MATLAB: How to delete axes and tick in figure

Precisely. As your question says, you're trying to mess with axis properties, not those of the figure.

Substitute

hAx=gca;        % get current axes handle
set(hAx,...)    % set desired property

There are routines specific for the ticks or the "dot" notation besides set

OK...did move content to Answer per request. :)

One additional note -- the above retrieves the current axes handle first, then uses it. This ensures always referring to the same axis in the event of some user interaction that could change focus.

Even better is to save the handle when the axes is created (although plot and friends will create one for themselves in which case the above is the way to retrieve it immediately).
