# Synopsis

(macro) long gdx_GetNumOfApproxAttrBrkPnts()

# Purpose

Get the current GDX number linear approximation Attribute break points.

# Description

This function gets the current GDX number of linear approximation attribute break points. The attribute break point indicates where the attributes for an entity change requiring a break in the data. For example, if the color of a subordinate entity changes from red to green, the the attribute breakpoint will indicate at which segment break point the attribute should change. The attribute break point is the count of segment break points at which an attribute changes.

# Return

Number of linear approximation attribute break points
