I am not really fluent with JS.Elevation but you have these interpolation options to "smooth" the graph
interpolation: "basis"
var el = L.control.elevation({ | theme: "lime-theme", //default: lime-theme | position: "topright", | //width: 450, | width: (document.getElementById('map').offsetWidth-20)-50, | //height: 80, | height: (50+(document.getElementById('map').offsetHeight)/8), | margins: { top: 15, right: 30, bottom: 30, left: 30 }, | useHeightIndicator: true, //if false a marker is drawn at map position | interpolation: "basis",
| // interpolation methods: | // linear - piecewise linear segments, as in a polyline. | // linear-closed - close the linear segments to form a polygon. | // step-before - alternate between vertical and horizontal segments, as in a step function. | // step-after - alternate between horizontal and vertical segments, as in a step function. | // basis - a B-spline, with control point duplication on the ends. | // basis-open - an open B-spline; may not intersect the start or end. | // basis-closed - a closed B-spline, as in a loop. | // bundle - equivalent to basis, except the tension parameter is used to straighten the spline. | // cardinal - a Cardinal spline, with control point duplication on the ends. | // cardinal-open - an open Cardinal spline; may not intersect the start or end, but will intersect other control points. | // cardinal-closed - a closed Cardinal spline, as in a loop. | // monotone - cubic interpolation that preserves monotonicity in y.

Thanks a lot for the quick reply! We will give this a closer look and try ... ... will let you know if it has worked out.
We are trying to realize a website for a hiking trail using leaflet with open top map. The website should also feature the elevation map for this hiking trail. We did the recording of the gpx file by hiking the trail and using a tracker to record the geo data. Our problem is that the gpx file does not 100 % perfectly match the data in the open topo map and therefore there are deviations in the elevation map that do not present the reality. Attached you'll see various unnatural spikes in the elevation map ...
How can we get rid of these spikes? Is there a way to fix this issue via configuration or additional command in Leaflet.Elevation?
