When you have no output variable for imhist() and you do not tell it which axes to display into, then it will call gca() to find the current axes. gca() will not look for axes whose handle visibility is turned off, but by default handle visibility is off for all uiaxes in app designer.
You need to either turn on handle visibility for the target axes and make it the current axes (not recommended), or else you have to pass the target axes to imhist (recommended)

DON'T use input for the name of a variable because it's already the name of a function that asks the user for a variable. Call it userInput or something. What does this show in the command window
I'd like to know if the badly-named "a" is actually a gray scale image, an RGB image, or a character array (string).
