Bqplot formatting saved image (png)

[FredDuj]

I'm new to bqplot. I'm trying to save image of plots in png to use them in some powerpoint presentations. I'm trying to find a way to do something similar to whtat you can do with matplotlib with the paramater " bbox_inches="tight" " in the .savefig function and also with the parameter "transparent=True". For the first one, I tried using "fig_layout = widgets.Layout(width='auto', height='auto')" in the parameter of the bqplot figure function, but it render the plot totally wrong and doesn't remove the gray and white outer boxes. Is there a way to make it work automatically without having to adapt manually for each plot ?
