Associating subplots legends with each subplot and formatting subplot titles

Hi @Emmanuelle, may be this would be easy to answer. How can I adjust size of whole subplot?
I have already played with column_widths and row_heights but they modify each cell keeping the whole subplot size same.

def make_subplots(
    rows=1,
    cols=1,
    shared_xaxes=False,
    shared_yaxes=False,
    start_cell="top-left",
    print_grid=False,
    horizontal_spacing=None,
    vertical_spacing=None,
    subplot_titles=None,
    column_widths=None,
    row_heights=None,
    specs=None,
    insets=None,
    column_titles=None,
    row_titles=None,
    x_title=None,
    y_title=None,
    **kwargs
):


Edit:
Never mind, discovered fig.update_layout(height=1000)
