How to minimize the white space from boxchart in MATLAB?

11 views (last 30 days)
I would like to minimize the whitespace of the figure (boxchart). I have tried to get a transparent background using built-in function exportgraphics():
But it doesn't work. Instead, it gives the following error:
Warning: Background transparency is not supported; using white instead.
I wonder if someone help me to remove the white space from the figure?
Thank you in advance.

Why not to use saveas(), e.g.:
...
saveas(t,'boxPlot0.jpg')
