plot in predesigned figure

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)

thank you for your answer!:)

However, in h i have programmed a complete detailed figure with grid and line width and everything.

and i want to put my graph directly into this preprogrammed figure. But it isnt working properly. Matlab is telling me:error using plot line cannot be a child of figure

the first argument in plot needs to be the handle to your axes, not the figure.

you can search for the axes by doing:

get(h,'Children')

if this returns an array of multiple graphics objects, then just use indexing to grab the axes and assign a handle to it, otherwise, get(h,'Children') would just show your axes and you can assign a handle to that.

[Walter Roberson]

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)

Thank you! It works better now!!
