How do I delete a premade column in VISIFire?

I have a VISIFire chart defined with a few columns in XAML. If I wanted to delete some columns during runtime in the C# code, how would I do that?

Hi,

You have to do it as shown below.

chart.Series[0].DataPoints.RemoveAt(0); // This will delete the first DataPoint. If you want to delete a diff DataPoint, you have to change the index.

or

DataPoint dp = chart.Series[0].DataPoints[0];
chart.Series[0].DataPoints.Remove(dp); // This will also delete the first DataPoint.

chart.Series[0].DataPoints.Remove(dp); // This will also delete the first DataPoint.

That will remove the first datapint in a series out of a chart. But what I am talking about is removing one entire series of datapoints. I am not talking about deleting an entire chart. But if I have a line graph chart, for example that charts 3 different things, I am going to have chart.Series[0], chart.Series[1], and chart.Series[2]. What if I wanted to remove chart.Series[2]?

You have to do it as shown below.

chart.Series.RemoveAt(2); // This will delete the third series.

or

DataSeries ds = chart.Series[2];
chart.Series.Remove(ds);
