[Petro]

Hi List.

Is there any way to select a region of interest in matplotlib figure inside of python notebook?

Thanks.

Petro.

OK.

I solved it :

https://github.com/matplotlib/matplotlib/issues/15852

%matplotlib widget
import matplotlib.pyplot as plt
from matplotlib.widgets import LassoSelector

fig, ax = plt.subplots()

def onSelect(x):
    print(x)

lineprops = {'color': 'red', 'linewidth': 1, 'alpha': 0.8}
lsso = LassoSelector(ax=ax,
                     onselect=onSelect,
                     lineprops=lineprops,
                     useblit=False)

plt.show()
