JavaScript snippet to get a vertex from a geotrace question?

MaryGraceMcClellan

I am trying to get just one vertex from a geotrace question - it seems possible using a JavaScript snippet, but I can't tell how to get into the geotrace output or what data type it is. My working snippet is below, I'm by no means proficient in JS, but this seemed to return at least something:

 

 

var lat = 0;
function myfunction(geotrace_data) {

    lat = JSON.stringify(geotrace_data);
    return lat;
}

Hello @MaryGraceMcClellan, 

Here is a sample that calculates the vertex for a specified index, but this index can be hard coded vs dynamically passed in from the survey.
