java.lang.Object | +--com.jrefinery.chart.Axis | +--com.jrefinery.chart.CategoryAxis | +--com.jrefinery.chart.HorizontalCategoryAxis
A horizontal axis that displays categories. Used for bar charts and line charts.
Note: the axis needs to rely on the plot for assistance with the placement of category labels, since the plot controls how the categories are distributed.

Method Summary | |
void |
configure()
Configures the axis against the current plot. |
void |
draw(java.awt.Graphics2D g2,
java.awt.geom.Rectangle2D drawArea,
java.awt.geom.Rectangle2D plotArea)
Draws the axis on a Java 2D graphics device (such as the screen or a printer). |
protected double |
getMaxTickLabelWidth(java.awt.Graphics2D g2,
java.awt.geom.Rectangle2D plotArea)
Returns the maximum width of the ticks in the working list (that is set up by refreshTicks()). |
boolean |
getSkipCategoryLabelsToFit()
Returns the flag that determines whether the category labels are to be skipped to avoid overlapping. |
boolean |
getVerticalCategoryLabels()
Returns a flag indicating whether the category labels are drawn 'vertically'. |
protected boolean |
isCompatiblePlot(Plot plot)
Returns true if the specified plot is compatible with the axis. |
void |
refreshTicks(java.awt.Graphics2D g2,
java.awt.geom.Rectangle2D plotArea,
java.awt.geom.Rectangle2D dataArea)
Creates a temporary list of ticks that can be used when drawing the axis. |
java.awt.geom.Rectangle2D |
reserveAxisArea(java.awt.Graphics2D g2,
Plot plot,
java.awt.geom.Rectangle2D drawArea,
double reservedWidth)
Returns the area required to draw the axis in the specified draw area. |
double |
reserveHeight(java.awt.Graphics2D g2,
Plot plot,
java.awt.geom.Rectangle2D drawArea)
Estimates the height required for the axis, given a specific drawing area, without any information about the width of the vertical axis. |
void |
setSkipCategoryLabelsToFit(boolean flag)
Sets the flag that determines whether the category labels are to be skipped to avoid overlapping. |
void |
setVerticalCategoryLabels(boolean flag)
Sets the flag that determines whether the category labels are drawn 'vertically'. |
void |
setVerticalTickLabels(boolean flag)
Sets the flag that determines whether the category labels are drawn 'vertically'. |
