  • Methodendetails

    • getChart

      public Chart2 getChart()
      Returns the parent chart of this dataset.
      Angegeben von:
      getChart in Schnittstelle BaseDataset
      Gibt zurück:
      the chart.

    • getCategoryGroup

      public Group getCategoryGroup()
      Returns the category group. The category group is the first group of chart.
      Gibt zurück:
      the group or null if this group was not initialized.

    • setCategoryGroup

      public void setCategoryGroup(Field field)
      Creates a category group on this field. This group is for sorting and consolidating records with same values on the group axis, i.e. the x axis by PlotOrientation.VERTICAL. To change the sort order of the data in this group get this with getCategoryGroup() and use the Group properties. SummaryField, SpecialField and GroupField are unsupported field types.
      Parameter:
      field - the group field (null not permitted)
      Löst aus:
      IllegalArgumentException - if field is null or has an unsupported field type.

    • removeCategoryGroup

      public void removeCategoryGroup()
      Removes the category group. Note: this dataset is incomplete without a category group and cannot be used by the chart in this case.

    • getSeriesGroup

      public Group getSeriesGroup()
      Returns the series group. The series group is the second group of chart.
      Gibt zurück:
      the group or null if this group was not initialized.

    • setSeriesGroup

      public void setSeriesGroup(Field field)
      Creates a series group on this field. This group is for sorting and consolidating records with same values on the group axis, i.e. the x axis by PlotOrientation.VERTICAL. The series group gets a own group axis by a chart with three axis (i.e. 3D chart) or it handles data grouped by category group. To change the sort order of the data in this group get this with getSeriesGroup() and use the Group properties. SummaryField, SpecialField and GroupField are unsupported field types.
      Parameter:
      field - (null not permitted)
      Löst aus:
      IllegalArgumentException - if field is null or has an unsupported field type.

    • setDataField

      public void setDataField(int summaryOperation, Field field, Field field2nd, int nth)
      Sets the data field which values will be calculated by the summary operation and shown in the chart as i.e. bar length. Creates a new SummaryField with this field, operation and parameters.
      For more information to supported value type of field and using of parameters 'field2nd' and 'nth' see SummaryField.
      Parameter:
      summaryOperation - the summary operation
      field - the data field
      field2nd - the second data field, used for example for weights in weighted average SummaryField.WEIGHTED_AVERAGE.
      nth - the nth parameter, used for example by summary operation SummaryField.NTH_LARGEST
      Löst aus:
      IllegalArgumentException - if the first or second field are required and null or have an unsupported value type.
      IllegalArgumentException - if nth is less than zero.
