    public class ChartData
    extends java.lang.Object
    implements IChartData

    Represents data used for a chart plotting.

    • Method Detail

      • getSeriesGroups

        public final IChartSeriesGroupCollection getSeriesGroups()

        Gets the groups of series. Read-only IChartSeriesGroupCollection.


        1) Each group of series contains series with combinable types. Groups of combinable series types defined and described with CombinableSeriesTypesGroup enum. Also each group of series contains series witch is plotted whether on primary axes or on secondary axes (not both cases in one group). So, principle of series grouping is a grouping by type groups mentioned above and by primary/secondary plotting type. 2) Group of series contains some series properies whitch is common for each series in group ("series group properties"). "Series group properties" in ChartSeriesGroup class is read/write. Each of "series group properties" can have a read-only projection in ChartSeries class.

      • getUseSecondaryCategories

        public final boolean getUseSecondaryCategories()

        If false then getSecondaryCategories() property return null and data in getCategories() property is used both for primary and secondary series. If true then data in getSecondaryCategories() property is used for secondary series and data in getCategories() property is used for primary series. Read/write boolean.


         Example. What categories are related to series - ChartData.Categories or ChartData.SecondaryCategories?
         
         if (series.getPlotOnSecondAxis() && series.getChart().getChartData().getUseSecondaryCategories())
         {
             // related categories are series.getChart().getChartData().getSecondaryCategories()
         }
         else
         {
             // related categories are series.getChart().getChartData().getCategories()
         }

        Specified by:
        getUseSecondaryCategories in interface IChartData
      • setUseSecondaryCategories

        public final void setUseSecondaryCategories(boolean value)

        If false then getSecondaryCategories() property return null and data in getCategories() property is used both for primary and secondary series. If true then data in getSecondaryCategories() property is used for secondary series and data in getCategories() property is used for primary series. Read/write boolean.


         Example. What categories are related to series - ChartData.Categories or ChartData.SecondaryCategories?
         
         if (series.getPlotOnSecondAxis() && series.getChart().getChartData().getUseSecondaryCategories())
         {
             // related categories are series.getChart().getChartData().getSecondaryCategories()
         }
         else
         {
             // related categories are series.getChart().getChartData().getCategories()
         }

      • readWorkbookStream

        public final byte[] readWorkbookStream()

        Writes the internally contained Excel workbook it into an in-memory stream.

        Specified by:
        readWorkbookStream in interface IChartData
        Returns:
        Returns an instance of MemoryStream containing a copy of the internally contained Excel workbook.
      • writeWorkbookStream

        public final void writeWorkbookStream(byte[] ms)

        Initializes the internally contained Excel workbook with user-specified value.

        Specified by:
        writeWorkbookStream in interface IChartData
        Parameters:
        ms - The user-supplied stream containing the entire Excel workbook.
      • getDataSourceType

        public final int getDataSourceType()

        Represents external workbook path if external data source, null otherwise

        Specified by:
        getDataSourceType in interface IChartData
      • getExternalWorkbookPath

        public final java.lang.String getExternalWorkbookPath()

        Represents data source of the chart

        Specified by:

      • setRange

        public final void setRange(java.lang.String formula)

        Set chart data range. Series and categories will be updated based on new data range. If amount of series in data range greater than count of series in the chart data then additional series with the same type as a last series in the current collection will be added to the end of the collection.

        Specified by:
        setRange in interface IChartData
        Parameters:
        formula - The cells data range formula. E.g: "Sheet1!$A$1:$C$4" , "SomeSheetName!A1:B100", "Sheet1!$A$1:$B$5;Sheet1!$D$1:$D$5".
        Throws:
        com.aspose.ms.System.ArgumentNullException - formula is null.
        com.aspose.ms.System.ArgumentException - formula has incorrect format.
