A series contains three parts (category, series name, and data). You can bind each part to an instance of the series data field. The entire chart control can not be bound; however, you can use a cell range or a formula to put data in the chart.
Using Code
You can add values to Spread with an array or dataset and then use a cell range to put those values in a chart control. This example uses an array to put data in the control.

object[,] values = { { "lg1", "lg2", "lg3" }, { "tt1", 2.0, 5.0 }, {"tt2",4.0,5.0 } }; fpSpread1.Sheets[0].SetArray(0, 0, values); FarPoint.Win.Spread.Model.CellRange cellRange = new FarPoint.Win.Spread.Model.CellRange(0,0,values.GetLength(0),values.GetLength(1)); fpSpread1.Sheets[0].AddChart(cellRange, typeof(FarPoint.Win.Chart.BarSeries), 400, 400, 0, 0); private void button1_Click(object sender, EventArgs e) { FarPoint.Win.Chart.BarSeries series = (FarPoint.Win.Chart.BarSeries)fpSpread1.Sheets[0].Charts[0].Model.PlotAreas[0].Series[0]; FarPoint.Win.Spread.Chart.SeriesDataField data = (FarPoint.Win.Spread.Chart.SeriesDataField)series.Values.DataSource; data.Formula = "Sheet1!$B$2:$E$1"; } |

Using Code
You can add values to Spread with an array or dataset and then use a cell range to put those values in a chart control. This example uses a data table to put data in the control.
Example
| C# | Copy Code |
|---|---|
DataTable dt = new DataTable("Test"); DataRow dr = default(DataRow); dt.Columns.Add("Series1"); dt.Columns.Add("Series2"); dr = dt.NewRow(); dr[0] = 1; dr[1] = 4; dt.Rows.Add(dr); dr = dt.NewRow(); dr[0] = 2; dr[1] = 5; dr = dt.NewRow(); dt.Rows.Add(dr); dr[0] = 3; dr[1] = 6; dt.Rows.Add(dr); fpSpread1.DataSource = dt; FarPoint.Win.Spread.Model.CellRange cellRange = new FarPoint.Win.Spread.Model.CellRange(0,0,2,2); fpSpread1.Sheets[0].AddChart(cellRange, typeof(FarPoint.Win.Chart.BarSeries), 400,400,0,0); |
