mplleaflet: Add the plot legend and select initial zoom

Question

Can anyone guide me on how to add a legend to the mplleaflet html plot. And second how to choose an initial zoom?

open shapefile in geopandas and plot property on interactive web map

Example Code:

import geopandas as gp
shapefile = 'shapefile/ne_50m_admin_0_countries.shp'
df_shapefile_countries = gpd.GeoDataFrame.from_file(shapefile)

import mplleaflet
ax = df_shapefile_countries .plot(column='pop_est')
mplleaflet.show(fig=ax.figure)

Example Image: I would like to immediately zoom for example to South East Asia

I think, right now, the functionality you want is not implemented.

For the first question regarding the legend, have a look here: https://github.com/jwass/mplleaflet/issues/35

For the second question, being creative, you can hack a zoom creating a transparent plot with the coordinates you want. For instance, have a look to the code below:

import matplotlib.pyplot as plt
import mplleaflet

fig, ax = plt.subplots()

# Your plot
ax.plot([10, 20, 30], [10, 20, 30])

# A second plot with some coordinates you want to use as the limits
# For instance, I want a plot with  x between (-100, 100)
ax.plot([-100, 100], [10, 30], alpha = 0)

mplleaflet.show(fig = ax.figure)

This is far from perfect, only works if you want a further view (I don't know if in english is said like this) but it is better than nothing. ax.set_xlim and/or ax.set_ylim doesn't work so you can't have a zoom closer than what you want to plot in the map.

I hope it helps.
