MATLAB: How to Make All Children of a Figure Invisible

childrenfigurevisible

Imagine I have a figure with three axes objects and a rectangle.

hfig = figure;
hax1 = axes;
hax2 = axes;
hax3 = axes;
hrec1 = rectangle;

How can I make the axes objects and the rectangle invisible, so only an empty figure is visible, and then again visible?

You could store them all in an array and then you can just use

set( hGraphics, 'Visible', 'off' )

Certainly your axes would be better as hAx(1), hAx(2), hAx(3) rather than 3 individual variables and you can tag a rectangle onto the same array too as it will just be an array of general graphics objects.

Recursively hunting through children can be a messy business although there may be functions that can do it, or something on file exchange.

A rectangle will be parented by an axes though so you can explicitly get children of your axes and hide them rather than starting at figure level.

Hide:

set(gca,'visible','off') %hide the current axes
set(get(gca,'children'),'visible','off') %hide the current axes contents

Show:

set(gca,'visible','on') %show the current axes
set(get(gca,'children'),'visible','on') %show the current axes contents

If needed replace gca by the handle of the axes you wish to work with

MATLAB: Odd getrect(FIG) behavior with subplots (r2015b)

Since the desired subplot is not known ahead of time, I ended up using this block of code to first figure out which axes was clicked on, and then collect the rectangle coordinates using rbbox.

%wait for user input. 
%determine if mouse or keyboard has been pressed
%only continue if left mouse button is clicked
keyDown = waitforbuttonpress;
isLeftMouseClick = strcmp(handles.output.SelectionType,'normal');
if keyDown == 0 && isLeftMouseClick
%keyDown 1 = keyboard
%keyDown 0 = mouse click
pt1 = handles.output.CurrentPoint;
%determine which axes has been clicked on
whichAxes = 0;
for kAxes = 1:6
    if inpolygon(pt1(1),pt1(2),xv(kAxes,:),yv(kAxes,:))
        whichAxes = kAxes;
        break
    end
end
if ~whichAxes
    %dont do anything
else
    %get extents with mouse
    finalRect = rbbox;
...
