Detailed Description

Responsible for drawing the grid of a QCPAxis.

This class is tightly bound to QCPAxis. Every axis owns a grid instance and uses it to draw the grid lines, sub grid lines and zero-line. You can interact with the grid of an axis via QCPAxis::grid. Normally, you don't need to create an instance of QCPGrid yourself.

The axis and grid drawing was split into two classes to allow them to be placed on different layers (both QCPAxis and QCPGrid inherit from QCPLayerable). Thus it is possible to have the grid in the background and the axes in the foreground, and any plottables/items in between. This described situation is the default setup, see the QCPLayer documentation.

Constructor & Destructor Documentation

◆ QCPGrid()

QCPGrid::QCPGrid ( QCPAxis * parentAxis )

explicit

Creates a QCPGrid instance and sets default values.

You shouldn't instantiate grids on their own, since every QCPAxis brings its own QCPGrid.

Sets the pen with which (major) grid lines are drawn.

◆ setSubGridPen()

void QCPGrid::setSubGridPen ( const QPen & pen )

Sets the pen with which sub grid lines are drawn.

Definition at line 7220 of file qcustomplot.cpp.

◆ setSubGridVisible()

void QCPGrid::setSubGridVisible ( bool visible )

Sets whether grid lines at sub tick marks are drawn.

◆ setZeroLinePen()

void QCPGrid::setZeroLinePen ( const QPen & pen )

Sets the pen with which zero lines are drawn.

Zero lines are lines at value coordinate 0 which may be drawn with a different pen than other grid lines. To disable zero lines and just draw normal grid lines at zero, set pen to Qt::NoPen.
