A more (computational) performant way to plot multiple scatter3 plots in a figure

I often need to plot multiple scatter3 plots in one figure.

My usual way works fine and is like this:

       figName = 'Something';
       figure('Name',figName,'Numbertitle','off');
       hold on;
                
        for(cnt = 1:size(patchListe,1))
 
            xval = patchListe{cnt,5}(:,1);
            yval = patchListe{cnt,5}(:,2);
            zval = patchListe{cnt,5}(:,4);      
            
            xmed = mean(xval);
            ymed = mean(yval);
            zmax = max(zval) ;
            
            scatter3(xval,yval,zval,1,zval);        
            text(xmed,ymed, zmax, num2str(cnt));            
        end

        colormap(jet(200)); colorbar;        
        title(['Something else', 'Interpreter', 'none');     
        grid on;

The result is the desired plot.

But the plot is very lazy.

Working with the plot, like Changing colormap or close the figure, takes several seconds

Is there a way to get a more performant and quicker working plot?

Btw: opengl is in fully hardware support mode

Use plot3 instead of scatter3

Scatter is verry expensive function
