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!

Give us the actual text to read instead of trying to look at pictures of it...
In general, to plot to a given figure/axes, you call plot() with the specific axes handle you wish to plot into...otherwise, by default it will use gca or create a new one if none are extant.

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)

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
plot(ax, [line1.x], [line1.y]
An alternative for that last line would be
plot([line1.x], [line1.y], 'Parent', ax)
