I need a figure that uses most of the area for a heatmap, and then has subplots of bar graphs on the side. I am doing this by creating a uipanel for my heatmap, and then a smaller uipanel to hold all of the bar graphs. The following example shows the figure that I want, but when I save it I get the following error:
Error using alternatePrintPath
Dimensions of arrays being concatenated are not consistent.
Error in alternatePrintPath
Error in print (line 83)
pj = alternatePrintPath(pj);
Error in saveas (line 181)
print( h, name, ['-d' dev{i}] )
Error in mre (line 18)
saveas(fig, 'test.png');
The problem has something to do with the legend. Also, if we don't plot the heatmap, the error goes away. Here is the code. I am using R2019b.
fig = figure;
heatmap_panel = uipanel('Position', [0, 0, .7, 1]);
heatmap_data = magic(10);
my_heatmap = heatmap(heatmap_panel, heatmap_data);
bars_panel = uipanel('Position', [.7, 0, .3, 1]);
subplot(2, 1, 1, 'Parent', bars_panel);
bar_data = [.2, .4, .4; .3, .3, .4]';
my_bar = bar(bar_data);
my_legend = legend({'group1', 'group2'});
saveas(fig, 'test.png');

Mathworks fixed it in 2020b.

the problem is at heatmap, which is not a real figure object.
Even if a single heatmap image object cannot be saved by saveas

I have brought this issue to the notice of our developers. They will investigate the matter further.

I have encountered a similar issue with 2019b. The same code seems to work for 2018b. As this is an internal function, I request MATLAB to suggest a solution. Thanks and appreciate it.
