Implement flexible height for chart visualization

[polyclick]

Enhancement description

Hi

I really enjoy using backtesting.py and its clean and simple approach to backtesting. But, one of the things that really turns me off is that I'm unable to resize the chart visualization's height.

I use backtesting.py in jupyter notebooks and I think being able to resize the chart to actually see something would be a really great addition.

Cheers!
