Hello EE,

I am creating series inside a chart in VB.Net with a DataSource.
when user click on another button I want the chart to refresh with another Datasource. But I need to delete all series first because otherwise I am having error saying series already exists. name must be unique.

I am not sure how to remove programmatically all the series with a for Next

any ideas?

in a loop maybe you can do this

while (Chart1.Series.Count > 0) Chart1.Series.RemoveAt(0);
