C#

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";
        }

Visual Basic
