ChartData.FromRange(CellRange) Method
Converts cell values to chart data for cells in the specified range.
Namespace: DevExpress.Spreadsheet.Charts
Assembly: DevExpress.Spreadsheet.v25.1.Core.dll
NuGet Package: DevExpress.Spreadsheet.Core
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| value | CellRange | A CellRange object that is the cell range of the worksheet. |
Returns
| Type | Description |
|---|---|
| ChartData | A ChartData object. |
Remarks
The example below demonstrates how to add data series to a chart and change the cell range containing data for a specific series.
The code uses the SeriesCollection.Add method to create a series and add it to the ChartObject.Series collection. To specify series values contained in the worksheet range, create a ChartData object using the ChartData.FromRange method and assign it to the Series.Values property.
The ChartText.SetReference method is used to link the Series.SeriesName to the content of the worksheet cell.
Worksheet worksheet = workbook.Worksheets["chartTask3"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Create a chart and specify its location.
Chart chart = worksheet.Charts.Add(ChartType.ColumnClustered);
chart.TopLeftCell = worksheet.Cells["H2"];
chart.BottomRightCell = worksheet.Cells["N14"];
// Add series using a worksheet range as the data source.
chart.Series.Add(worksheet["D2"], worksheet["B3:B6"], worksheet["D3:D6"]);
chart.Series.Add(worksheet["F2"], worksheet["B3:B6"], worksheet["F3:F6"]);
// Change the data range for the series values.
chart.Series[1].Values = ChartData.FromRange(worksheet["E3:E6"]);
// Specify the cell that is the source for the series name.
chart.Series[1].SeriesName.SetReference(worksheet["E2"]);
