Pie chart render data is wrong after update datasource in series

Hi Syncfusion Team,
I'm using AccumulationChartComponent ​to build a Pie chart, but I face the issue:

After I changed dataSource, the Pie chart rendered was wrong.

Sample: https://stackblitz.com/edit/react-cmsyce?file=index.js

1 . Click the button to change dataSource.

2. Check data=> In new dataSource, we have only one record in the data source, but in the Pie chart UI, we have 6 records.

Expect: After clicking the button, the Pie chart is shown with only 1 record.

Hi Ton,

Greetings from Syncfusion.

We have modified the provided sample based on your requirement. We can set the dataSource of the Pie chart by using the reference of the component. Please find the below stackblitz link for the modified sample for your reference.

Sample link: https://stackblitz.com/edit/react-hbkezw?file=index.js

Code Snippet:

clickHandler() {

        const index = Math.round(Math.random() * (data1.length - 1));

        const newData = data1.map((item) => {

            const value = Math.round(Math.random() * 100);

            return { ...item, y: value };


        this.pie.series[0].dataSource = [newData[index]];



Initial Rendering:

After clicking on button:

Kindly, revert us if you have any concerns.
