How to minimize the white space from boxchart in MATLAB?

I would like to minimize the whitespace of the figure (boxchart). I have tried to get a transparent background using built-in function exportgraphics():

https://it.mathworks.com/help/matlab/creating_plots/save-figure-with-minimal-white-space.html

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')

[HAT]

@Sulaymon Eshkabilov When I use saveas(), the white background doesn't change.
