public class AxisTheta

extends ChartNode

The angular axis in a polar plot.

AxisTheta is created by Polar as its child. It can be retrieved using the method Polar.getAxisTheta().

The angles are labeled using the TextFormat attribute, which is set to "0.##\\u00b0", where \\u00b0 is the Unicode character for degrees. This labels the angles in degrees. More generally, TextFormat can be set to a NumberFormat object to format the angles in degrees.

TextFormat can also be set to a MessageFormat object. In this case, field {0} is the value in degrees, field {1} is the value in radians and field {2} is the value in radians/. So, for labels like 1.5\\u03c0, where \\u03c0 is the Unicode character for , set TextFormat to new MessageFormat("{2,number,0.##\\u03c0}").

The number of tick marks ("Number" attribute) is set to 9, but autoscaling can change this value.

Method Detail

paint

public void paint(Draw draw)

Paints this node and all of its children.

Specified by:

paint in class ChartNode

Parameters:

draw - the Draw object to be painted

getTicks

public double[] getTicks()

Returns the value of the "Ticks" attribute, if set. If not set then computed tick values are returned. These are the positions at which the angles are labeled.

Returns:

the double value of the "Ticks" attribute, if defined. Otherwise, computed tick values are returned. The ticks are in radians, not degrees.

setWindow

public void setWindow(double min,
                      double max)

Sets the window for an AxisTheta. The default Window is [0,2pi].

Parameters:

min - a double which specifies the initial angular value, in radians.

max - a double which specifies the final angular value, in radians.

setWindow

public void setWindow(double[] window)

Sets the window for an AxisTheta.

Parameters:

window - a double array of length two containing the angular range.

getWindow

public double[] getWindow()

Returns the window for an AxisTheta.

Returns:

a double array of length two containing the angular range of the window.
