How to link axes on colormap?

Hi,

I am trying to link the axes so that the two subplots share the same colourbar, I have tried using linkaxes(hAxis, 'x'), linkaxes(hAxis.CurrentAxis, 'x'). Can anyone help me please? The code is below:

hFig = gcf;
set(gcf,'Color','w','Units','Normalized');
for i = 1:nSubplot
    subplot(1,nSubplot,i);
    if isempty(xmin)
        [hAxis, hPatch, hColorbar] = DOTHUB_plotSurfaceImage(rmap.gmSurfaceMesh,img(i,:),viewAng,shadingtype,varInputs.colormap);
    else 
        [hAxis, hPatch, hColorbar] = DOTHUB_plotSurfaceImage(rmap.gmSurfaceMesh,img(i,:),viewAng,shadingtype,varInputs.colormap, xmin, xmax);
    end 
    set(hAxis,'FontSize',16);
    hColorbar.Location = 'South';
    tmp = hColorbar.Position;
    hColorbar.Position = [tmp(1) tmp(2) tmp(3) tmp(4)];
    hColorbar.AxisLocation = 'out';
    ylabel(hColorbar,subplotLabels{1,i})

end
% [~,fname,~] = fileparts(dotimg.fileName);
fname = filename;
linkaxes(axes,'x');

Hello Emilia,

I understood from your question that you are unable to link the axes. You may use the gca for current axes or chart

hAxis = gca;
linkaxes(gca, "xy", "color");

You may look at this documentation for further details:

Hope it helps!!
