Banzai chart no longer adding dynamic series

edited March 2017 in Problems
In the previous release you could create a before render snippet and change the series as shown in this post It appears that in the new Banzai release adding to the series list no longer adds a new series to the chart when it's rendered. The snippet still runs, it just seems that the chart doesn't pickup any newly created series before it is rendered.

    Hi, Justin. That should still be supported, but we did make some changes under the hood for Banzai, so we could have a bug. Care to share that snippet so I can take a closer look?

    Of course, here is the snippet that is currently working in our production environment using the old build. This just keeps a running total of a single series in the chart and adds it as a line. The console log at the end correctly shows the new series being added it just doesn't show up during runtime.
    var chartObj = arguments[0],
    $ = skuid.$;

    // figure out how many series there are, since this is
    // for asset flows there would be anywhere from 1 to 4
    // different series
    var assetTypeNumber = chartObj.series.length;

    if (assetTypeNumber && assetTypeNumber > 0) {
    var cumulativeAssets = [];
    var sumAssets = 0;

    // each series has a data array all of the same size
    for (var i = 0; i < chartObj.series[0].data.length; ++i) {
    for (var j = 0; j < assetTypeNumber; ++j) {
    sumAssets += chartObj.series[j].data[i];


    var newSeries = {
    id: 'CumulativeAssets',
    name: 'Cumulative Assets',
    data: cumulativeAssets,
    type: 'column',
    xAxis: chartObj.series[0].xAxis,
    yAxis: chartObj.series[0].yAxis,

    // add the new series to the very end of the current
    // chart series
    chartObj.series[chartObj.series.length] = newSeries;

    Hmmm... Nothing jumps out at me. I took this snippet and pared it down a bit to not rely on a particular data model, added it a column chart and it appears to work:
    var chartObj = arguments[0],  $ = skuid.$,  newSeriesData = [];  for (var i = 0; i < chartObj.series[0].data.length; ++i) {     //  Just use a dummy value     newSeriesData.push((i+1) * 100000); }      chartObj.series[chartObj.series.length] = {     id: 'CumulativeAssets',     name: 'Cumulative Assets',     data: newSeriesData,     type: 'column',     xAxis: chartObj.series[0].xAxis,     yAxis: chartObj.series[0].yAxis, };      console.log(chartObj);
    If you try that snippet, does the extra (bogus) series show up? Does this help shed any more light on why this wouldn't be working?

    Ah.. I see what has changed. So before the series in the chartObj was a simple number array. Now it is an Object with a y property for the value. So as I was just adding the values it was trying to concatenate objects instead of just adding the values together.

    For those interested, in my above snippet if you replace
    sumAssets += chartObj.series[j].data[i];
    sumAssets += chartObj.series[j].data[i].y;
    everything works as expected in Banzai

    Ah! Yes, we did standardize on the config objectย format for series data across all our chart types for Banzai. Previously, each of the categories used a slightly different format. Just a note, it does look like you can mix and match formats within a single chart, but of course, if you've got a snippet that is relying on Skuid constructing your series data in one format or another, it will need to be updated.
