Question

I want to add dynamic series in the chart.

I have a data like date,totalamount. i would like to plot those points on chart.

I get the data from sql database and bind.

i want to plot the data from datatable which will update dynamically.

Series newSeries=new Series();
newseries.ChartType=SeriesChartType.Line;
newSeries.BorderWidth = 3;
Chart1.Series.Add(newSeries);
newSeries.XValueMember = "date1";
newSeries.YValueMembers = "total";
Chart1.DataBind();

this is plotting at last series of the tree view.
please help me on this?

Answer 1

 foreach(DataRow row in myDataSet.Tables["Query"].Rows)
    {
        // For each Row add a new series
        string seriesName = row["SalesRep"].ToString();
        Chart1.Series.Add(seriesName);
        Chart1.Series[seriesName].ChartType = SeriesChartType.Line;
        Chart1.Series[seriesName].BorderWidth = 2;

        for(int colIndex = 1; colIndex < myDataSet.Tables["Query"].Columns.Count; colIndex++)
        {
            // For each column (column 1 and onward) add the value as a point
            string columnName = myDataSet.Tables["Query"].Columns[colIndex].ColumnName;
            int YVal = (int) row[columnName];

            Chart1.Series[seriesName].Points.AddXY(columnName, YVal);
        }
    }
