Axis.setTitlePos

ChartDirector Ver 3.1 (PHP Edition Edition)

Axis.setTitlePos

Usage

setTitlePos(alignment[, titleGap])

Description

Set the position of the axis title relative to the axis.

By default, the axis title will be drawn at the middle of the axis outside the plot area. You may change the location of the title. For example, instead of drawing the x-axis title at the middle of the axis, you may want draw it at the end of the axis.

The current version of ChartDirector supports the following alignment positions when drawing axis titles.

Axis	Default	Supported
Bottom x-axis	BottomCenter	TopLeft, TopRight, TopCenter, Left, Right, BottomLeft, BottomRight, BottomCenter
Top x-axis	TopCenter	TopLeft, TopRight, TopCenter, Left, Right, BottomLeft, BottomRight, BottomCenter
Left y-axis	Left	Left, TopLeft
Right y-axis	Right	Right, TopRight

Arguments

Argument	Default	Description
alignment	(Mandatory)	The position of the title relative to the axis. Please refer to the table above for the valid values.
titleGap	6	The distance between the axis title and the axis in pixels.

Return Value

None

ntent"> A TextBox object that represents the prototype of the axis labels. You may use the methods of this object to fine-tune the appearance of the axis labels.

artDirector test the "too small" condition using the formula:

maxDataValue * zeroAffinity < minDataValue

where zeroAffinity by default is 0.8.

Similar "zero affinity" mechanism applies to the top end of the axis for a purely negative axis. If the data range contains both positive and negative values, the zero point is always included.

The zeroAffinity argument of the setAutoScale method allows you to modify the zero affinity when performing auto-scaling. Zero affinity should be between 0 and 1. A large value encourages ChartDirector to start the axis from zero.

A zero affinity of 1 means the axis always includes the zero point. A zero affinity of 0 means that the axis is scaled purely according to the data range, without any preference for the zero point.

Note that zero affinity is ignored for log scale axis as log scale axis cannot contain 0.

Arguments

Argument	Default	Description
topExtension	0.1	The top portion of the axis that no data point should fall into. For example, a value of 0.2 means no data value will fall within the top 20% of the axis. The topExtension must be between 0 to 1.
bottomExtension	0.1	The bottom portion of the axis that no data point should fall into. For example, a value of 0.2 means no data value will fall within the bottom 20% of the axis. The bottomExtension must be between 0 to 1.
zeroAffinity	0.8	The tendency of ChartDirector to include zero in the axis during auto-scaling. The value must be between 0 and 1. A large value encourages ChartDirector to start the axis from zero. A value of 1 means the axis always includes the zero point. A value of 0 means there is no preference for the zero point during auto-scaling.

Return Value

None
