setDataLabelStyle([font[, fontSize[, fontColor[, fontAngle]]]])

Enable data labels and set their styles.

This method affects all data labels in the layer. To set the style for one particular data set only, use DataSet.setDataLabelStyle.

Data labels are text used label data points in the layer. Different layer types put data labels in different positions. For example, in a bar chart, data labels are put at the internal end of the bar. For a line chart, data labels are put above the data points.

For some chart types, the position of the data labels can be manipulated by calling the TextBox.setAlignment method of the TextBox object returned by the setDataLabelStyle method.

See Font Specification for details on various font attributes.

Argument	Default	Description
font	""	The font used to draw the labels.
fontSize	8	The font size used to draw the labels.
fontColor	TextColor	The color used to draw the labels.
fontAngle	0	Set the rotation of the font.

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