WindAxis

public WindAxis(java.lang.String label)

Standard constructor - initialises the attributes for a ValueAxis.

Parameters:

label - The axis label;

Method Detail

isAutoRange

public boolean isAutoRange()

Returns true if the axis range is automatically adjusted to fit the data, and false otherwise.

setAutoRange

public void setAutoRange(boolean auto)

Sets a flag that determines whether or not the axis range is automatically adjusted to fit the data, and notifies registered listeners that the axis has been modified.

Parameters:

auto - Flag indicating whether or not the axis is automatically scaled to fit the data.

getAutoTickValue

public boolean getAutoTickValue()

Returns true if the tick value is calculated automatically, and false otherwise.

setAutoTickValue

public void setAutoTickValue(boolean flag)

Sets a flag indicating whether or not the tick value is calculated automatically, and notifies registered listeners that the axis has been modified.

Parameters:

flag - The new value of the flag;

isShowGridLines

public boolean isShowGridLines()

Returns true if the grid lines are visible for this axis, and false otherwise.

setShowGridLines

public void setShowGridLines(boolean show)

Sets the visibility of the grid lines and notifies registered listeners that the axis has been modified.

getGridStroke

public java.awt.Stroke getGridStroke()

Returns the Stroke used to draw the grid lines (if visible).

setGridStroke

public void setGridStroke(java.awt.Stroke stroke)

Sets the Stroke used to draw the grid lines (if visible) and notifies registered listeners that the axis has been modified.

Parameters:

stroke - The new grid line stroke.

getGridPaint

public java.awt.Paint getGridPaint()

Returns the Paint used to color the grid lines (if visible).

setGridPaint

public void setGridPaint(java.awt.Paint paint)

Sets the Paint used to color the grid lines (if visible) and notifies registered listeners that the axis has been modified.

Parameters:

paint - The new grid paint;

autoAdjustRange

protected abstract void autoAdjustRange()

Automatically determines the maximum and minimum values on the axis to 'fit' the data;

translateValueToJava2D

public abstract double translateValueToJava2D(double dataValue,
                                              java.awt.geom.Rectangle2D plotArea)

Converts a value from the data source to a Java2D user-space co-ordinate relative to the specified plotArea. The coordinate will be an x-value for horizontal axes and a y-value for vertical axes (refer to the subclass).

Note that it is possible for the coordinate to fall outside the plotArea.
