Child Class	Description
ezcGraphAxisBoxedLabelRenderer	Renders axis labels centered between two axis steps like normally used for bar charts.
ezcGraphAxisCenteredLabelRenderer	Renders axis labels centered below the axis steps.
ezcGraphAxisNoLabelRenderer	Renders axis labels like known from charts drawn in analysis
ezcGraphAxisExactLabelRenderer	Renders axis labels like known from charts drawn in analysis

Properties

bool	read/write	$innerStep Indicates if steps are shown on the inner side of axis.

int	read/write	$majorStepSize Size of major steps.
bool	read/write	$minorStepCount Count of minor steps.
int	read/write	$minorStepSize Size of minor steps.
bool	read/write	$outerGrid Indicates if the grid is shown on the outer side of axis.
bool	read/write	$outerStep Indicates if steps are shown on the outer side of axis.
