Josh,

When are you trying to run this snippet. If you run a before-render snippet for the chart, you should be able to delete a series.

maybe:

delete chartObj.series[1];

Thanks for the reply, Matt.

I am running this as a before-render snippet on the chart.

Here’s part of the code where I tried adding in your snippet and the error that is thrown. My javascript skills are strictly amateur, so maybe I’m missing something ‘obvious’.

    var newSeries = {        id: 'Cumulative',

        name: 'Percent of ECN',

        data: cumulative,

        type: 'column',

        yAxis: chartObj.seriesj0].yAxis,

    };

    

    // replace first series with new cumulative series

    chartObj.seriesj0] = newSeries;  delete chartObj.seriesj1];

A couple quesitons:

• Does chartObj.series[1] exist? That assumes there are at least two series to start with. the first series you’re replacing with ‘newSeries’ and the second you’re trying to delete?


• What part of the code is causing the error? (Expand the error to see the call stack and see if you can trace it back to any of your own code.
