How to assign xlabel,ylabel from my selected popup menu list?

Hello everyone,

I have created a basic GUI which plots scatter plot in 2D and 3D

Based on 3 popup menus i.e.X,Y,Z graphs gets plotted.

I want to assign xlabel, y label and z label based upon selected variable from popupmenu

x,y,z labels should get automatically updated upon changing variable from popup menu.

I have tried using get,set functions but I could not do it.

Any help on this topic!!!

Are you using App Designer? Or are you using uicontrol()?

Answer 1

If App Designer:

value = app.DropDown.Value;
value2 = app.DropDown2.Value;
value2 = app.DropDown2.Value;

if value == 'Option 2' &  value2 == 'Option 3' & value3 == 'Option 3'
    xlabel(app.UIAxes,'X Label')
    ylabel(app.UIAxes,'Y Label')
    zlabel(app.UIAxes,'Z Label')
else
     xlabel(app.UIAxes,'X Label2')
    ylabel(app.UIAxes,'Y Label2')
    zlabel(app.UIAxes,'Z Label2')
end

If uicontrol:

c = uicontrol(f,'Style','popupmenu','callback',@DropDownCallback); % dropdown box 1
c2 = uicontrol(f,'Style','popupmenu','callback',@DropDownCallback); % dropdown box 2
c3 = uicontrol(f,'Style','popupmenu','callback',@DropDownCallback); % dropdown box 3

value = c.Value;
value2 = c2.Value;
value2 = c3.Value;
function DropDownCallback(~,~)
    if value == 'Option 2' &  value2 == 'Option 3' & value3 == 'Option 3'
        xlabel('X Label')
        ylabel('Y Label')
        zlabel('Z Label')
    else
        xlabel('X Label2')
        ylabel('Y Label2')
        zlabel('Z Label2')
    end
end

Hi Kevin...I'm not using Appdesigner....Here is my code

X = get(handles.popupmenuX, 'value');

Y = get(handles.popupmenuY, 'value');

Z = get(handles.popupmenuZ, 'value');

filename = handles.filename;

[x,y,z] = readExcelColumns(filename, X, Y, Z)

axes(handles.axes1);

plot_style = get(handles.plotstyle,'value');

set(handles.statustext, 'Visible', 'on'); drawnow;

switch plot_style

case 2

scatter(handles.axes1,x,y,20,z,'filled');

grid on

colormap(jet);

colorbar;

case 3

scatter3(handles.axes1,x,y,z,[],z,'filled');

colormap(jet);

colorbar;

end

I'm not sure how you created your popupmenus. I'm going to assume with uicontrol.

handles.popupmenuX = uicontrol(gcf,'Style','popupmenu','Units','normalized','Position',[.5 .5 .2 .2],'String',{'Option 1','Option 2','Option 3'},'Callback',@DropDownCallback);
handles.popupmenuY = uicontrol(gcf,'Style','popupmenu','Units','normalized','Position',[.3 .3 .2 .2],'String',{'Option 1','Option 2','Option 3'},'Callback',@DropDownCallback);
handles.popupmenuZ = uicontrol(gcf,'Style','popupmenu','Units','normalized','Position',[.7 .7 .2 .2],'String',{'Option 1','Option 2','Option 3'},'Callback',@DropDownCallback);

function DropDownCallback(~,~)
X  = get(handles.popupmenuX, 'value');
Y  = get(handles.popupmenuY, 'value');
Z  = get(handles.popupmenuZ, 'value');

plot_style = get(handles.plotstyle,'value');
set(handles.statustext, 'Visible', 'on'); drawnow;
filename = handles.filename;
[x,y,z] = readExcelColumns(filename, X, Y, Z);

if X == 1 &&  Y == 2 && Z == 3
    plot_style = 2;
else
    plot_style = 3;
end

switch plot_style
    case 2

        scatter(handles.axes1,x,y,20,z,'filled');
        grid on
        colormap(jet);
        colorbar;
        xlabel('X Label')
        ylabel('Y Label')
        zlabel('Z Label')
    case 3
        scatter3(handles.axes1,x,y,z,[],z,'filled');
        colormap(jet);
        colorbar;
        xlabel('X Label2')
        ylabel('Y Label2')
        zlabel('Z Label2')
end
end
