Is there a way to receive click events from charts?

Let's say I have a pie chart summarizing a table below it of tasks. The pie chart is showing the percentage of done vs not done items.

I want to be able to click on the "not done" section of the pie chart and then filter the table to only include "not done" items.

You have this option for the majority of charts. The property is called selected but is unavailable for pie charts. I created a quick example to show you how to use it in a bar chart.

Click on the bar until you see it is selected; the table should be refreshed accordingly.

from taipy.gui import Gui, State
import pandas as pd

data = pd.DataFrame({"values":[60, 40],
                     "labels":["Done", "Not Done"]})

data_for_table = data
selected = []

md = """
<|{data}|chart|type=bar|y=values|x=labels|selected={selected}|>

<|{data_for_table}|table|>
"""

def on_change(state: State, var_name: str, var_value):
    if var_name == "selected":
        if len(var_value) == 1:
            label = state.data.loc[var_value[0], 'labels']
            state.data_for_table = state.data.where(state.data["labels"] == label)
        else:
            state.data_for_table = state.data

Gui(page=md).run()

For your use case with a pie chart, I would suggest using a selector or toggle instead. We will investigate expanding the selected property to pie charts.

Ah ok thanks, I could use a bar chart instead

Yes, you could. We are currently investigating whether we can expand it to pie charts for your use case. (Issue)
