10.14. Identifying Parts of a Scale

You can find out what part of the scale a coordinate resides in by using the identifymethod:

$value = $scale->identify(x, y);

The identify method returns a string containing one of the following values: "slider", "trough1", "trough2", or an empty string (if the coordinates don't refer to any of these parts).
