How can capture the close event of finplot?

The below function cannot capture the event.
How can capture the close event of finplot?

def closeEvent(self, event):
print('Window closed')

Possibly finplot.FinWindow.close?

[hwjung92]

That is not work.
I mean when I click the window close (X) at the right-top, how can I receive the event in the fplt?
I want to clear all fplt data when closing a fin-plot window.

If you use finplot.show() some clearing is done for you when the window is closed. Otherwise replace finplot.FinWindow.close with a method of your choosing.

In my application, if finplot is not cleared well, the main program has a conflict for using Timer.
matplotlib provide the below function to receive the close event.
Do you provide it like a below code?

=======================================================
class Plotter:
def init(self):
self.fig = plt.figure()
self.fig.canvas.mpl_connect('close_event', self.dispose)
plt.plot(1, 2, 'r*')
plt.show()
print "done with plotter"

def dispose(self, event):
    plt.close('all')
    print "disposed"

This seems to work.

#!/usr/bin/env python3

import finplot as fplt
import numpy as np
import pandas as pd

def update():
    dates = pd.date_range('01:00', '01:00:01.200', freq='1ms')
    prices = pd.Series(np.random.random(len(dates))).rolling(30).mean() + 4
    ax.reset()
    fplt.plot(dates, prices, ax=ax)
    fplt.refresh()

ax = fplt.create_plot(maximize=False)
fplt.timer_callback(update, 0.02)
fplt.show()

Not sure what you're problem is, since you're not supplying.
