Hi, I have 4 subplots of which the 1st one is a heatmap. I would like to automatically put this into clipboard and have tried the following/

          ax1=subplot(1,4,1)    
          h = heatmap(T,'data1','data2','ColorVariable','data5');
          
          h.Colormap = cool;          
          %h.FontSize = 6
          h.XLabel = 'X position (um)';
          h.YLabel = 'Y position (um)';
          h.CellLabelFormat = '%.1f'
     
         %Copy to clipboard
         currAxes = gca
         newFig = figure('visible','off');
         newHandle = copyobj(currAxes,newFig);
         print(newFig,'-dmeta');   
         %print('-clipboard','-dmeta')
         
         

However this doesn't seem to work, is what I want to achieve possible?

thanks

Jason

You can copy the heatmap handle on to a new figure. Here's a functional demo with comments.

% load built-in matlab data
load patients
tbl = table(LastName,Age,Gender,SelfAssessedHealthStatus,...
    Smoker,Weight,Location);
% Plot a scatter plot & heatmap 
fh1 = figure(); 
subplot(2,1,1)
plot(tbl.Age, tbl.Weight,'bo')
subplot(2,1,2)
h = heatmap(tbl,'Smoker','SelfAssessedHealthStatus');
% Create new figure and copy heatmap to figure
fh2 = figure(); 
h2 = copyobj(h,fh2); 
% reposition heatmap axes
h2.Position = [0.13 0.11 0.65 0.80];

In the code from your question, it appeared to me as if you are trying to copy the heatmap to another figure. You mentioned that it's not working but didn't provide more detail.

To copy the figure on the clipboard,

print(fh2, '-dmeta')

Where fh2 is the figure handle.

If the problem persists, please provide the full error message or a detailed description of what's not working.
