Method Detail

paintNeedle

Shape paintNeedle(Graphics2D g2d,
                  AbstractGauge gauge,
                  Double value,
                  double x,
                  double y,
                  double angle,
                  double radius,
                  NeedleStyle style)

Paints a needle onto a meter

Parameters:

g2d - the Graphics context onto which the needle is to be drawn

gauge - the Meter component onto which the needle will be painted

x - the x coordinate of the needle pivot

y - the y coordinate of the needle pivot

angle - the angle in degrees

radius - the radius of the needle in pixels

style - the needle style, which provides preferred styling details. A renderer should respect these preferences but on occasions may have good reason to override them.
