Dimple JS add vertical line

I am trying to draw a vertical line in Dimple. I have seen this post: How to draw a vertical line with dimple?

However, the example provided there is not working for me. It is only adding a point where instead I'd like a line to be drawn. I cannot find anything in the docs, nor on StackOverflow, nor via Googling and I would think this should be an easy thing to do- but so far it has proven not to be. Any help would be appreciated.

    var svg = dimple.newSvg("#chartContainer", 590, 400);
    d3.tsv("http://dimplejs.org/data/example_data.tsv", function (data123) {
      var data = [{'name': "name1", "percentChange": 120}, {'name': "name2", "percentChange": 80}, {'name': "name3", "percentChange": 100}];

      var x2 = myChart.addMeasureAxis("x", "percentChange");
      x2.title = "Percent of last month's sales"
      var y = myChart.addCategoryAxis("y", "name");
      y.addOrderRule("name");
      y.title = null;
      y.showGridLines = true;

      /*Regional average*/
      var y2 = myChart.addPctAxis("y", "Dummy");
      var s3 = myChart.addSeries("Regional", dimple.plot.area, [x2, y2]);
      s3.data = [{
        "Regional": "Regional",
        "Dummy": 1,

      var s = myChart.addSeries(["percentChange", "name"], dimple.plot.bar);

      // Set some custom display elements for each series shape
      s.afterDraw = function (shape, data) {

        var shape = d3.select(shape);

        // Add some bar labels for the yValue
        svg.append("text")

      s.addEventHandler("mouseover", onHover);

   function onHover(e) {
     e.selectedShape[0][0].style.fill = "#00924f";

That approach won't work with a measure axis on x. However the solution is actually much simpler in this case. After drawing you can add a line with a bit of d3:

svg.append("line")
    .attr("x1", x._scale(105))
    .attr("x2", x._scale(105))
    .attr("y1", myChart._yPixels())
    .attr("y2", myChart._yPixels() + myChart._heightPixels())
    .style("stroke", "red")
    .style("stroke-dasharray", "3");

This uses a couple of the internal methods in dimple for height and width as well as the x axis scale for positioning the line horizontally. I've made it red and dashed but changing the style lines you can format it however you wish - or set a class instead and set the appearance in css.
