        <Option value="Dummy">Dummy</Option>
      </Select>

      <Pie {...config} />
      <Button onClick={updateChartValue}>Load Data </Button>
    </div>
  );
}

The variable pieChartData should get loaded based on selectedInputValue when performing the plot.on("element:click") event. But, On the pie chart element click, the state variable selectedInputValue holds the initialized value only. Other places outside the events of the charts are all able to access the new updated value for selectedInputValue. Any thoughts on this?
