Detailed Description
Circular gridlines for a PolarPlot.This subclass of Subject will notify upon the following conditions:
- The setRadialInterval() method is called.
- Everything else documented in Gridlines.
- See also:

Constructor & Destructor Documentation
| virtual PolarGridlines::~PolarGridlines | ( | ) | [protected, virtual] |
A plug-in cannot create this object, it can only retrieve an already existing object by calling PolarPlot::getGridlines().
The polar plot manages its own instance of this object.

Member Function Documentation
| virtual void PolarGridlines::setRadialInterval | ( | double | angle | ) | [pure virtual] |
Sets the angular interval of the lines extending out from the center of the polar plot.
- Parameters:
-
angle The angular interval for the lines extending out from the plot center in degrees. The value should be between 0.0 and 360.0.
- Subject Notifications:
- This method notifies Subject::signalModified() if the given interval is different than the current interval.
| virtual double PolarGridlines::getRadialInterval | ( | ) | const [pure virtual] |
Returns the angular interval of the lines extending out from the center of the polar plot.
- Returns:
- The angular interval for the lines extending out from the plot center in degrees. The value ranges from 0.0 to 360.0.
