Hello,

For my project, I would like to integrate a surf plot onto a GUI interface with a slider that update the plot inside the interface.

I tested the surf plot apart and it works fined but when i try to take the same structure as "Heatmap version" of the code that worked fine i got the error:

"Error using surf

Z must be a matrix, not a scalar or vector.

Error in TimeLapseInterpolatedMap (line 72)

heatObj = surf(uip,Vq);"

Of course, I understood that putting "iup" in the first argument of surf function doesn't work but then I don't know how to integrate it with my GUI.

Con you help me ?

Thank you !

% HEATMAP VERSION (WORKING)
data = M;
    fig = uifigure(); 
    uip = uipanel(fig,'Position', [20 100 500 300]); 
    heatObj = heatmap(uip, data(:,:,1),'Colormap', hsv,'CellLabelColor', 'none','ColorLimits', [-500 400]);
    heatObj.Title = 'Electrode Fluorescence Heatmap - Frame 1';
    n = size(data,3);
    uis = uislider(fig,'Position',[50 50 450 3],...
        'Value',1, ...
        'Limits', [1,n], ...
        'MajorTicks', 0:200:n, ...
        'MinorTicks', []);
    %valueChangedFcn for actualisation only when cursor is dropped
    uis.ValueChangingFcn = {@sliderChangingFcn, data, heatObj};
    
    function sliderChangingFcn(~,event,data,heatObj)
        % Update heatmap and title with new selection of data
        value = round(event.Value);
        heatObj.ColorData = data(:,:,value);
        heatObj.Title = sprintf('Electrode Fluorescence Heatmap - Frame #%d',value);
    end
    
% SURF VERSION (NOT WORKING) 
    data = M;
    fig = uifigure();
    uip = uipanel(fig,'Position', [20 100 500 300]); 
    [Xq,Yq] = meshgrid(1:0.1:12);
    Vq = interp2(data(:,:,1),Xq, Yq, 'cubic');
    heatObj = surf(uip, Vq);
    n = size(data,3);
    uis = uislider(fig,'Position',[50 50 450 3],...
        'Value',1, ...
        'Limits', [1,n], ...
        'MajorTicks', 0:200:n, ...

        value = round(event.Value);
        heatObj.ColorData = data(:,:,value);
        heatObj.Title = sprintf('Electrode Fluorescence Heatmap - Frame #%d',value);
    end

Create an uiaxes inside the uipanel or you can simply use uiaxes instead of uipanel inside the uifigure.

Sorry I didnt expressed myself correctly I was looking to set the z value range. But your comment helped as I saw where to put a zlim (it put i previoulsy in the cursor loop which is useless).

Last question, do you know how to keep view point of the 3D graph during the cursor consecutives updates ? If not thank you, you already helped a lot.
