I am trying to create an interactive interface that has a drop down menu with two options "2D Plot" and "3D Plot" and when one of these options is selected it launches the respected graph. I am finding the drop down menu to be kinda complicated for me so if having two push buttons is easier then that will also work. Here is what I have with my code so far but I keep getting a message that says "Error while evaluation UIControl Callback". Please let me know if you can help! Thank you!

global Figure2D Figure3D
[num,txt,raw] = xlsread('Surface_Data.xlsx', 'PDA-PTFE_PFQNM_SA003ASCII3', 'A2:SR513');
[ny,nx] = size(num);
L = 20; %micrometer
B = 20; %micrometer
x = linspace(0,L,nx);
y = linspace(0,B,ny);
[X,Y] = meshgrid(x,y);
Figure2D = figure;
pcolor(X,Y,num);
Figure3D = figure;
surf(X,Y,num);
plotStyle2D = uicontrol(Figure2D,'Style','popupmenu');
plotStyle2D = uicontrol(Figure3D,'Style','popupmenu');
menuItems = [" Select Plot " "2D Plot" "3D Plot"];
dropDownPosition = [20 80 100 40];
plotStyle2D.String = menuItems;
plotStyle2D.Position = dropDownPosition;
plotStyle3D.String = menuItems;
plotStyle3D.Position = dropDownPosition;
plotStyle2D.Callback = @PlotType;
H
function PlotType(src,event)
    val = src.Value;
    str = src.String;
    
    if(str{val} == '2D Plot')
        figure(Figure2D);
    elseif(str{val} == '3D Plot')
        figure(Figure3D);
    end
   
end

What are the other errors you are getting?

You should also be setting the Callback for plotStyle3d

does this work for you?

function PlotType(src,event)
    val = src.Value;
    str = src.String;
    
    if strcmp(src.String,'2D Plot')
        figure(Figure2D);
    elseif strcmp(src.String,'3D Plot')
        figure(Figure3D);
    end
   
end
