MATLAB: Applying hold in multiple figure window?

2d plotfigureplotplotting

Dear all, I have plotted 4 different curves in 4 different windows using figure(1), figure(2), figure(3), figure(4). I want to apply 'hold' on every figure windows such that I can plot some other curves on each. If I use 'hold', Matlab is holding only figure(1) and not to others.

Best Answer

f1 = figure(1) ;ax1 = axes ;hold(ax1,'on')
f2 = figure(2) ;ax2 = axes ; hold(ax2,'on')
for i = 1:5
    plot(ax1,rand(10,1))
    plot(ax2,rand(10,1))
end

MATLAB: Bind plot with some figure

In this case, you should specify which axes to plot on. See the example below:

%Initialize the figures
Gx = gobjects(1, 4);
Ax = gobjects(1, 4);
for k = 1:4
    Gx(k) = figure(k);
    Ax(k) = axes(Gx(k));
end
%Plot to the Nth figure
for k = 1:4
    plot(Ax(k), rand(1, 10), rand(1, 10));  
          ^ INCLUDE AXES HERE!  %To plot to 1st figure, use Ax(1). 2nd figure, use Ax(2). etc.
end

MATLAB: Plotting in same figure window

>> help figure

FIGURE Create figure window.
  FIGURE, by itself, creates a new figure window, and returns
  its handle.
    FIGURE(H) makes H the current figure, forces it to become visible,
    and raises it above all other figures on the screen.  If Figure H
    does not exist, and H is an integer, a new figure is created with
    handle H.

So, if you want to always plot on the same figure, you can use h=figure(1), which may not be good in some cases because it over-write the existing figure 1.

Or, you can use close() to close the existing figure first.

In any case, remember figure has a handle. It is like the figure's ID. You can always specify to which figure you want to plot.

h1=figure(1);
set(h1,'name','myname');
plot(1:10);
