i have created 3 "axis" and a push button.
I have saved 3 variables in a mat file that I would like to display as a histogram. I loaded the file, but cannot display it on the graph. Any suggestion how to do it?

If you want to draw histogram on data, please try using histogram() function. Here's how I plot histogram in my application:
properties (Access = public)
HueHistogram matlab.ui.control.UIAxes; %UIAxis defined in application (UI)
end
methods (Access = public)
function DrawHistogram(obj)
% Below I'm using histogram function, and passing the axis
% object I have created in my application (HueHistogram)
% obj.Blocks.HueAvg is my data vector, 200 - is the number of bins
histo = histogram(HueHistogram, [obj.Blocks.HueAvg], 200);
end
end
