trying to plot data in gui based on a popupmenu

Hey everybody,

Hope everybody is doing great. So I have a popupmenu, that when I choose options from it, it creates options for a second popupmenu. Based on the selction in the second popupmenu I would like to plot data using a pushbutton. Does anyone know how?

Thanks!

What aspect of it is causing a problem?

plotting the data based on the selction of the second menu.

what gui are you using? App Designer or Guide?

Or are you skipping GUIDE and writing it yourself in native Matlab?

[Aser Zidan]

I am using guide. And as sure as heck I am not that good to skip it and write it myself.

GUIDE is probably holding you back. It did for me. It isn't actually really hard to do it yourself.

Anyway, you should call your plotting function in the callback function of that secondary dropdown. You should make sure to use the axes as the parent object in your plot function. (most function will support it as a Name,Value pair: 'Parent',handles.axes1)

My small guide to avoid GUIDE:

• Make a figure (with f=figure;) and look into the doc for figure which properties you want to turn off (you probably want to set Menu and Toolbar to 'none')
• Create buttons and axes and everything you need with functions like uicontrol and axes. Save the handles to each element to fields of a struct (like handles.mybutton=uicontrol(___);)
• When you've finished loading all data (and saving it to fields of your handles struct), and creating all the buttons, save your handles struct to the guidata of your figure like this guidata(handles.f,handles);. (You can also use getappdata and setappdata)
• You can set the Callback property of many objects. If you do, use a function name with an @ in front, or a char array that can be evaluated to valid code. (like @MyFunction or 'disp(''you pushed the button'')')
• Callback functions will be called with two arguments: the first is a handle to the callback object, the second is eventdata that may contain special information. To get access to your data, just use handles=guidata(gcbo);. You can replace the gcbo function with the name of the first input to your callback function if you prefer.
• More information about callbacks can be found in multiple places in the doc, for example here.

that was more than phenomenal, thanks.
