Measure Visualization
Since version: 1.7
The measure visualization profile allows the map author to write an expression that evaluates to a value used to drive the visualization of measure values along a line. This is used in the context of linear referencing hatching of m-aware lines. When each measure value is drawn, the measure value is interpolated for the marker location and passed into the script. It is expected that the script returns the desired value to draw via a text graphic in a marker symbol.
Context
The following products implement this profile:

Spatial reference
The spatial reference of the map in which $feature is rendered determines the spatial reference of the expression's execution context.
