Reproducible Example

import pandas as pd
from lightweight_charts import Chart


chart = Chart(inner_width=0.5)
sub_chart = chart.create_subchart(position="right", width=0.5, height=1)

df1 = pd.read_csv(f'./data.csv')
df2 = df1.copy()

chart.events.range_change += lambda chart, bef, aft: print(chart, bef, aft)
sub_chart.events.range_change += lambda chart, bef, aft: print(chart, bef, aft)

chart.set(df1)
sub_chart.set(df2)

if __name__ == "__main__":
    chart.show(block=True)
