GanttTwoGroupsDataset

public GanttTwoGroupsDataset(Chart2 chart)

Creates a new empty dataset.

Method Detail

getSeriesGroup

public Group getSeriesGroup()

Returns the series group. The series group is the second group of chart.

Returns:

the group or null if this group was not initialized.

Since:

setSeriesGroup(Field), removeSeriesGroup()

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 handles data grouped by the 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.

Parameters:

field - (null not permitted)

Throws:

java.lang.IllegalArgumentException - if field is null or has an unsupported field type.

removeSeriesGroup

public void removeSeriesGroup()

Removes the series group. Note: this dataset is incomplete without a series group and cannot be used by the chart.

verify

public java.lang.String verify(ChartStyle style)

Verifies the group and sum properties of current dataset.

Specified by:

verify in interface BaseDataset

Overrides:

verify in class GanttOneGroupDataset

Parameters:

style - the chart style

Returns:

the error message or empty string if all properties are correct.

getReferencedObject

public java.util.List getReferencedObject()

FOR INTERNAL USE ONLY

Overrides:

getReferencedObject in class GanttOneGroupDataset

Returns:

FOR INTERNAL USE ONLY

saveGroups

protected void saveGroups(java.io.PrintWriter out,
                          int depth)

Writes the groups properties to output. Overwrites this to save intern properties direct to PrintWriter without building a StringBuffer.

Overrides:

saveGroups in class GanttOneGroupDataset

Parameters:

out - the output

depth - the depth of XML indent

getName

protected java.lang.String getName()

FOR INTERNAL USE ONLY Returns the XML attribute name for this dataset.

Overrides:

getName in class GanttOneGroupDataset

Returns:
