Hi @jarod46,
talk is cheap, show me the code..

Ha, it's a generaly question, I'm not sure what I need to share, basically I have a timer which regularly call an ajax function which query if there is new locations to add to the current track.
I tried with several functions like controlElevation.load
, controlElevation._addData
, controlElevation.addData
, controlElevation.loadLayer
...
function updateLocations(data) {
if (data && Array.isArray(data) && data.length > 0) {
var newFeature = {
"type": "Feature",
"geometry": {
"type": "LineString",
"coordinates": []
},
"properties": {
"name": "KTrackPlus",
"description": "",
"coordTimes": [],
}
};
for (var i = 0; i < data.length; i++) {
if (i > 1000) break;
var newCoords = [Number(data[i].lng), Number(data[i].lat), Number(data[i].alt), Number(data[i].timestamp)];
newFeature.geometry.coordinates.push(newCoords);
var date = new Date(Number(data[i].timestamp) * 1000);
newFeature.properties.coordTimes.push(date.toISOString());
mostRecentTT = data[i].timestamp;
locs.push(newCoords);
}
controlElevation._loadLayer(newFeature);
/*if (firstTime) {
//var jsonStr = JSON.stringify(newFeature);
//controlElevation.load(jsonStr);
trackLayer = controlElevation._loadLayer(newFeature);
}
else {
controlElevation.addData(newFeature, trackLayer);
controlElevation._initMapIntegrations(trackLayer);
}*/
controlElevation.redraw();
}
}

I think you are already on the right path: addData
→ _addData
→ _addGeoJSONData
→ _addPoint
...
You probably just need to dive a little deeper into the code's flow and choose the one that's right for you:
leaflet-elevation/src/control.js
Lines 340 to 369 in ea15556
leaflet-elevation/src/control.js
Lines 371 to 387 in ea15556
NB: As you go further and further down, you will have to handle everything else by yourself, eg: _addLayer
, _fireEvt
, ...
leaflet-elevation/src/control.js
Lines 29 to 44 in ea15556
