ChartData Class

Data plotted on a chart.

Namespace: DevExpress.Spreadsheet.Charts

Assembly: DevExpress.Spreadsheet.v21.2.Core.dll


public class ChartData


The ChartData class instance is the data used as Series.Arguments, Series.Values or the Series.BubbleSize parameters for ChartType.Bubble type charts.

The ChartData instance is usually created from data located in the spreadsheet cells using the static ChartData.FromRange method, or from literal data contained in the array using the ChartData.FromArray method.

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.

Dim worksheet As Worksheet = workbook.Worksheets("chartTask3")
workbook.Worksheets.ActiveWorksheet = worksheet

' Create a chart and specify its location.
Dim chart As 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.
