Method Detail

getSeriesExpression

public JRExpression getSeriesExpression()

Specified by:

getSeriesExpression in interface JRCategorySeries

Returns:

the expression of the series name. The value of this expression can be any java.lang.Comparable object.
Note that this expression may return different values with each iteration, which in turn will result in the dataset having multiple category series, even though a single <categorySeries> tag was used inside <categoryDataset>. However, this expression usually returns a java.lang.String constant, and there are several <categorySeries> tags that introduce multiple category series in the dataset.

getCategoryExpression

public JRExpression getCategoryExpression()

Specified by:

getCategoryExpression in interface JRCategorySeries

Returns:

the expression of the name of the category for each value inside the series specified by the series expression. Categories are java.lang.Comparable objects (not necessarily java.lang.String objects).

getValueExpression

public JRExpression getValueExpression()

Specified by:

getValueExpression in interface JRCategorySeries

Returns:

the value expression, a java.lang.Number value for each category in the specified series.

getLabelExpression

public JRExpression getLabelExpression()

Specified by:

getLabelExpression in interface JRCategorySeries

Returns:

the label expression. If present, this expression allows customization of the item labels in the chart.

getItemHyperlink

public JRHyperlink getItemHyperlink()

Description copied from interface: JRCategorySeries

Returns the hyperlink specification for chart items.

The hyperlink will be evaluated for every chart item and an image map will be created for the chart.

Specified by:

getItemHyperlink in interface JRCategorySeries

Returns:

hyperlink specification for chart items

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class Object
