How can I plot histogram matlab to uiaxes APP designer?

Hi Everyone,

Could some one know how to plot histogram of an image to uiaxes ?

This is my code:

v = videoinput("winvideo", 2, "YUY2_640x480"); % capure image from webcam

v.ReturnedColorspace = "grayscale"; % convert to gray

v.ROIPosition = [133 114 410 300]; % crop image

snapshot1 = getsnapshot(v); % capture image

imhist(snapshot1,app.UIAxes) % Plot historam

Thanks all!

Han

imhist is not supported in App Designer yet (as best I can tell). However, you may be interested in this example, which uses histogram instead to show the red, green and blue content of an image.

Or open directly in MATLAB with the following command

openExample('matlab/AppdImageHistogramsExample')

Hi, just wondering if you know if imhist will ever be supported in App Designer? Seems like every plot type should be supported really?

You could try the approach @Adam Danz describes here: https://www.mathworks.com/matlabcentral/answers/705623-using-dendrogram-in-app-designer#answer_587838

I've attached a simple example. Here's what the results look like using this example.
