explicit |
Creates a QCPPolarGrid instance and sets default values.
You shouldn't instantiate grids on their own, since every axis brings its own grid.
void QCPPolarGrid::setAntialiasedSubGrid | ( | bool | enabled | ) |
Sets whether sub grid lines are drawn antialiased.
void QCPPolarGrid::setAntialiasedZeroLine | ( | bool | enabled | ) |
Sets whether zero lines are drawn antialiased.
void QCPPolarGrid::setAngularPen | ( | const QPen & | pen | ) |
Sets the pen with which (major) grid lines are drawn.
void QCPPolarGrid::setAngularSubGridPen | ( | const QPen & | pen | ) |
Sets the pen with which sub grid lines are drawn.

A convenience function to easily set the QPainter::Antialiased hint on the provided painter before drawing the major grid lines.
This is the antialiasing state the painter passed to the draw method is in by default.
This function takes into account the local setting of the antialiasing flag as well as the overrides set with QCustomPlot::setAntialiasedElements and QCustomPlot::setNotAntialiasedElements.
Implements QCPLayerable.

protectedvirtual |
Draws grid lines and sub grid lines at the positions of (sub) ticks of the parent axis, spanning over the complete axis rect. Also draws the zero line, if appropriate (setZeroLinePen).
Implements QCPLayerable.
