I have a winform that has two radio buttons. Depending on the button that is checked a certain line chart should display. For various reasons I can not use separate winforms.

The radio button is checked as follows:

private void radioButtons_CheckedChanged(object sender, EventArgs e)
{
this.ultraChart1.DataSource = GetColumnData(uI, noiseCriteria, newPath, roomCriteria);
this.ultraChart1.DataBind();
}

The graphs currently are made as follows:

private DataTable GetColumnData(int[] userInput, int NC, string path, int RC)
{
if (radioButton1.Checked)
{
// Make annotation for NC #
Infragistics.UltraChart.Resources.Appearance.PaintElement paintElement1 = new Infragistics.UltraChart.Resources.Appearance.PaintElement();
Infragistics.UltraChart.Resources.Appearance.EllipseAnnotation ellipseAnnotation1 = new Infragistics.UltraChart.Resources.Appearance.EllipseAnnotation();
ellipseAnnotation1.Height = -1;
ellipseAnnotation1.Location.Column = 6;
ellipseAnnotation1.Location.LocationX = 0;
ellipseAnnotation1.Location.LocationY = 0;
ellipseAnnotation1.Location.Row = 11;
ellipseAnnotation1.Location.Type = Infragistics.UltraChart.Shared.Styles.LocationType.RowColumn;
ellipseAnnotation1.Location.ValueX = 0;
ellipseAnnotation1.Location.ValueY = 0;
ellipseAnnotation1.PE = paintElement1;
ellipseAnnotation1.TextStyle.HorizontalAlign = System.Drawing.StringAlignment.Center;
ellipseAnnotation1.Width = -1;
this.ultraChart1.Annotations.Annotations.Add(ellipseAnnotation1);
ellipseAnnotation1.Text = "NC: " + NC.ToString();

The problem is that the graphs start to do unwanted things. Lines turn the wrong color when buttons are checked multiple times because it is still getting old information from last line overrides. Annotation are hard to read because they get thicker from not being erased from the last time, or annotation don't erase at all even though they are no longer relevant.

Thank you in advance.
