Drawings deleting locally only

[esteban2006]

Expected Behavior

Drawings deleting locally only

when a drawing is rendered, and later removed or price updated it should be update on the drawing.json file as well

Current Behaviour

Any drawings on the chart will not be deleted or updated from drawings.json

i am adding some data for testing data.csv

Reproducible Example

import pandas as pd
from lightweight_charts import Chart


def get_bar_data(symbol, timeframe):
    if symbol not in ('AAPL', 'GOOGL', 'TSLA'):
        print(f'No data for "{symbol}"')
        return pd.DataFrame()
    return pd.read_csv(f'bar_data/{symbol}_{timeframe}.csv')


def on_search(chart, searched_string):
    new_data = get_bar_data(searched_string, chart.topbar['timeframe'].value)
    if new_data.empty:
        return
    chart.topbar['symbol'].set(searched_string)
    chart.set(new_data)
    
    # Load the drawings saved under the symbol.
    chart.toolbox.load_drawings(searched_string)


def on_timeframe_selection(chart):
    new_data = get_bar_data(chart.topbar['symbol'].value, chart.topbar['timeframe'].value)
    if new_data.empty:
        return
    # The symbol has not changed, so we want to re-render the drawings.
    chart.set(new_data, keep_drawings=True)


if __name__ == '__main__':
    chart = Chart(toolbox=True)
    chart.legend(True)

    chart.events.search += on_search
    chart.topbar.textbox('symbol', 'TSLA')
    chart.topbar.switcher(
        'timeframe',
        ('1min', '5min', '30min'),
        default='5min',
        func=on_timeframe_selection
    )

    df = get_bar_data('TSLA', '5min')

    chart.set(df)

    # Imports the drawings saved in the JSON file.
    chart.toolbox.import_drawings('drawings.json')
    
    # Loads the drawings under the default symbol.
    chart.toolbox.load_drawings(chart.topbar['symbol'].value)  
    
    # Saves drawings based on the symbol.
    chart.toolbox.save_drawings_under(chart.topbar['symbol'])  

    chart.show(block=True)
    
    # Exports the drawings to the JSON file upon close.
    chart.toolbox.export_drawings('drawings.json')
