Problem updating Manhattan plot data using CanvasXpress.updateData(data)

[sammyjava]

Hiya! I've used updateData(data) to update a heatmap, and now I'm trying to do so with a Manhattan scatter plot. I have a selector that determines which data to plot, and I use a function to generate the plot, including the default when the page is first loaded. Here's how I'm updating the canvas:

     // create/update the CanvasXpress object
     var cx = CanvasXpress.$('canvasx');
     if (cx==null) {
         cx = new CanvasXpress('canvasx', data, conf, evts);
     } else {
         cx.updateData(data);
     }

The initial plot created with the constructor is fine (first attached image). However, when I change the selection, updateData() leaves a blue spinner on the plot, with no plotted data, and the legend gets "-log10(p) vs Manhattan" appended (second attached image). It seems like a bug! I've pasted the data, conf, evts below with the two data options.

     var evts = {
         "click": function(o, e, t) {
             var markerName = o.y.vars[0];
             var markerIdentifier = genome+"."+markerName;
             window.open("/"+"${WEB_PROPERTIES['webapp.path']}"+"/geneticmarker:"+markerIdentifier);
         }
     }

  var conf = {

I'm using the most recent CanvasXpress 37.8 given by

wget https://www.canvasxpress.org/dist/canvasXpress.css
wget https://www.canvasxpress.org/dist/canvasXpress.min.js

Note: I also need to update conf because the chromosome lengths change, but that's a separate issue. I'd be fine with blowing away the canvasx object and replacing it, if that's an option. I get Javasacript errors when I simply try to replace it with a new constructor call.
