I'm using App Designar, I have this interface with a Panel

When you push in the bottom, starts a function that show an image and then update the image painting things, then another image, then update it...

This is the code:

     frameRGB = read(vidReader,i);
      frameGray = rgb2gray(frameRGB);
      flow = estimateFlow(opticFlow,frameGray);
      figure(1);imshow(frameRGB);impixelinfo
      hold on

I need to show this image and their subsequent updates in the panel and not in the figure. The panel is app.myPanel

I solved this turning the panel into an axe and then:

line([0,N],[500,550],'LineWidth',3,'Color','#7E2F8E', 'Parent', panel);

You can create a child uiaxis for the uipanel parent and specify the uiaxis handle as parent while using imshow.

frameRGB = read(vidReader, i);
frameGray = rgb2gray(frameRGB);
flow = estimateFlow(opticFlow, frameGray);
ax1 = uiaxes(app.myPanel);
imshow(frameRGB, 'Parent', ax1);
hold on
