Overview
Unless defined otherwise, all the point labels of the chart share the same settings. Those global settings are available through the pointLabels property of the CFXGlobalAttributes. The CFXGlobalAttributes class is accessible through the allSeries property of the chart.
Properties
alignment
Gets or sets the vertical alignment for the point label.
Declared In
ChartFX.h
angle
Gets or sets the angle of the point label.
Discussion
The default rotation angle is 0 degree (i.e., horizontal). Use a positive number to rotate the labels from lower left to upper right. Use negative degrees to rotate text from upper left to lower right.
When generating charts using Xcode and Objective-C , the angles "0" and "90" are the only supported configurations.
This property is also available in the CFXSeriesAttributes or CFXPointAttributes objects. Therefore, a label angle can be set to a specific series or point instead of all series in the chart.
To use this property, you must make sure the pointLabels are visible.

Constants
CFXStringAlignment
The StringAlignment type specifies how a string is aligned in reference to the bounding rectangle. A bounding rectangle is used to define the area in which the text displays.
typedef enum {
} CFXStringAlignment;
Constants
CFX- Specifies that alignment is towards the origin of the bounding rectangle. May be used for alignment of characters along the line or for alignment of lines within the rectangle. For a right to left bounding rectangle, the origin is at the upper right.
CFX- Specifies that alignment is centered between origin and extent (width) of the formatting rectangle.
CFX- Specifies that alignment is to the far extent (right side) of the formatting rectangle.
