Constructor Details

SubCategoryAxis

public SubCategoryAxis(String label)
Creates a new axis.
Parameters:
label - the axis label.

Method Details

addSubCategory

public void addSubCategory(Comparable subCategory)
Adds a sub-category to the axis.
Parameters:
subCategory - the sub-category.

draw

public AxisState draw(Graphics2D g2,
                      double cursor,
                      Rectangle2D plotArea,
                      Rectangle2D dataArea,

cursor - the cursor location.
plotArea - the area within which the axis should be drawn (null not permitted).
dataArea - the area within which the plot is being drawn (null not permitted).
edge - the location of the axis (null not permitted).
plotState - collects information about the plot (null permitted).
Returns:
The axis state (never null).

drawSubCategoryLabels

protected AxisState drawSubCategoryLabels(Graphics2D g2,
                                          Rectangle2D plotArea,
