filter is not a function problems

[AlfieJ]

Good morning.

I've been looking to replace our charting library and this morning I started evaluating Epoch. But I quickly ran into two problems. The first was an error on line 429 of epoch.js:

d3Seconds = d3.time.format('%I:%M:%S %p');

It appears that a recent d3 update changed things related to time, so modifying that line to read:

d3Seconds = d3.timeFormat('%I:%M:%S %p');

solved that problem.

But now I'm running into a problem inside Base.prototype.getVisibleLayers on line 669:

return this.data.filter(function(layer) {

Both Firefox 49 and IE 11 are giving the same error that the filter function doesn't exist, so it's not the pre-IE9 filter issue.

Fixing this one isn't as clear to me...what can I do to fix this?

Thank you, Alfie

For those that are interested, when you pass the plot data to Epoch, you pass an array of data, as is clearly shown in the instructions, like so:

var lineChartData = [
  // The first series
  {
    label: "Series 1",
    values: [ {x: 0, y: 100}, {x: 20, y: 1000}, ... ]
  },

  // The second series
  {
    label: "Series 2",
    values: [ {x: 20, y: 78}, {x: 30, y: 98}, ... ]
  },

  ...
];

Which I was not doing. My apologies.
