Set chart height to full browser window height or at least to a set value

[AlexStox]

Hi guys, is there a way to override 'plot' method to make the scalable height of the chart or at least to set some height?
For instance, right now it plots the chart only on a half of the page height in the browser, so I'd like to make it bigger in height.
I tried a few approaches, but no luck, e.g. this one:

self.sma2[-1]: self.buy() elif self.sma1[-1] < self.sma2[-1]: self.sell() # Run the backtest with the customized plot bt = CustomBacktest(GOOG, SmaCross, cash=10_000, commission=0.002) stats = bt.run() bt.plot()">

from backtesting import Backtest, Strategy
from backtesting.test import SMA, GOOG  # Example data
from bokeh.layouts import gridplot
from bokeh.plotting import show
from bokeh.models import DatetimeTickFormatter

class CustomBacktest(Backtest):
    def plot(self, **kwargs):
        # Call the original plot method
        fig = super().plot(**kwargs)

        # Apply full-height adjustments to all figures
        for f in fig.select(dict(type="Figure")):
            f.sizing_mode = "stretch_both"  # Adjust each figure for full resizing
            f.plot_height = 800  # Ensure height is large enough to fill the screen
            if hasattr(f.xaxis[0], "formatter"):
                f.xaxis[0].formatter = DatetimeTickFormatter(days="%d %b", months="%m/%Y")

        # Apply sizing_mode to the overall layout
        fig.sizing_mode = "stretch_both"

        # Show the adjusted figure
        show(fig, browser=None if kwargs.get("open_browser", True) else 'none')
        return fig

# Define a simple strategy
class SmaCross(Strategy):
    def init(self):
        self.sma1 = self.I(SMA, self.data.Close, 10)
        self.sma2 = self.I(SMA, self.data.Close, 20)

    def next(self):
        if self.sma1[-1] > self.sma2[-1]:
            self.buy()
        elif self.sma1[-1] < self.sma2[-1]:
            self.sell()

# Run the backtest with the customized plot
bt = CustomBacktest(GOOG, SmaCross, cash=10_000, commission=0.002)
stats = bt.run()
bt.plot()

Referring to the documentation of Backtesting.py, it states that 'The height is currently non-adjustable.' Therefore, you likely won't be able to achieve your desired outcome using the built-in bt.plot(). Alternatively, you might consider exporting the necessary data to Excel to create the chart.

Well, thank you, I saw and read this in the documentation before posting the question here. But still think there is a way to override the library method.

I tried a few approaches and they didn't work.
So, maybe someone knows why this is impossible (to change the chart height).

I've been playing around with this for a while, because ideally the plot would be fullscreen.
This works for me, but the result (the panes not retaining designated aspect) is an issue I didn't find how to overcome.

bt = Backtest(...)
fig = bt.plot(open_browser=False)
fig.sizing_mode = 'stretch_both'
from bokeh.io import show
show(fig)

If anybody finds a way to make them look pretty, please open a PR.
