pytplot legend_location does not work correctly in some cases

[nickssl]

Legend option "spedas" for "legend_location" places the legend outside the viewable window in the following example. Clicking on the slider button of the plot, and making the subplot parameter "right" smaller, makes the legend visible, but this should happen automatically if possible.

from pyspedas import time_double
from pytplot import options, tplot_options, store_data, tplot


def test_legend():
    trange = ["2022-03-23/00:00:00", "2022-03-23/23:59:59"]

    # Empty panel
    tn = time_double(trange)
    store_data("empty_panel", data={"x": tn, "y": [0, 0]})

    # Panel 1: AE index
    panel1 = "empty_panel"
    options(panel1, "ytitle", "AE index")
    options(panel1, "ysubtitle", "[nT]")
    options(panel1, "legend_names", ["THEMIS AE"])
    options(panel1, "legend_location", "spedas") # doesn't work correctly


    # Create plot
    vars = [panel1, panel1, panel1]
    plot_title = "Overview  Plot (" + trange[0] + ")"
    tplot_options("title", plot_title)
    tplot_options("show_all_axes", False)
    tplot(vars)


test_legend()
