Surf plot on GUI interface

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, ...
'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

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.

Are you looking for function view?
I don't have too much experience in 3D view and hence may not understand your needs, Sorry.
