Greetings from Syncfusion.
We have analyzed your query. From that we would like to let you know that the series not refreshed when we used selectedDataIndex property through button click. That’s why the problem is occurred. By calling chart refresh() method, you can resolve this problem. We have modified the attached sample. Now point selection is working fine as you expect. Please find below,
