While working with Charting control in Windows forms. I found an issue in binding and rebinding the data into the chart control.
Here is the small piece of code to plot the data in a chart
string[] seriesArray = { "Semester1", "Semester2", "Semester3" };
int[] pointsArray = { Convert.ToInt32(0), Convert.ToInt32(semester[1]), Convert.ToInt32(semester[2]) };
this.chart1.Palette = ChartColorPalette.Berry;
this.chart1.Titles.Add("Growth of the Student");
for (int x = 0; x < seriesArray.Length; x++)
{
Series series = this.chart1.Series.Add(seriesArray[x]);
series.Points.Add(pointsArray[x]);
}
While loading the data for the second time, i got an error "A chart element with the name already exists in the 'SeriesCollection'." The reason is, the chart is already having the series related data bound to it.
Solution:
chart1.Series.Clear();
chart2.Series.Clear();
chart3.Series.Clear();
this.chart1.Titles.Clear();
this.chart2.Titles.Clear();
this.chart3.Titles.Clear();
