newbie: is it possible to get data from the last lap (like speed or elapse time) in simpleDataField?

Question

I'm trying to figure out where to find data on the possibilities of a simpleDataField (perhaps I shouldn't be looking here). I'm trying to use data like the average HR, speed, elapsed time (duration) of the last lap. Thank you for helping me out.

You can't get the data directly, but you can see when a lap occurs, and do your own calculations in compute(). 
 Here's a simple one that just shows the lap number, but it's the basis. onTimerLap() is called when their's a new lap. 
 using Toybox.WatchUi;

class LapsView extends WatchUi.SimpleDataField {

	var laps=0;
	
 // Set the label of the data field here.
 function initialize() {
 SimpleDataField.initialize();
 label = "Laps";
 }
 
 function onTimerLap() {
 laps++;
 }

 // The given info object contains all the current workout
 // information. Calculate a value and return it in this method.
 // Note that compute() and onUpdate() are asynchronous, and there is no
 // guarantee that compute() will be called before onUpdate().
 function compute(info) {
 // See Activity.Info in the documentation for available information.
 return laps;
 }

}
