How do you get value of string in pie chart vb .net?

To get the value of a string in a pie chart in VB.NET, you typically use the Series collection of the chart control. First, ensure your data is added to the series as points, where each point has a corresponding label and value. You can then retrieve the string values using the Points collection of the series. For example, you can access a specific point's label with chart.Series("SeriesName").Points(index).AxisLabel and its value with chart.Series("SeriesName").Points(index).YValues(0).
