nvd3 plotting multiple series on stacked area chart

Question

I'm trying to create a stacked area chart using nvd3. Currently I'm creating the json data to be graphed and testing it against nvd3 live code section on nvd3 website, at the moment I've got this:

[
    {
        "values": [[1382812284000, 0], [1382818677000, 1], [1382818677000, 2], [1382819934000, 3], [1382820167000, 4], [1382822993000, 5], [1382823894000, 6], [1382825059000, 7], [1382827775000, 8]], 
        "key": "first"
    },
    {
        "values": [[1382812284000, 0], [1382819096000, 1], [1382822399000, 2], [1382825092000, 3], [1382826256000, 4], [1382826291000, 5], [1382827074000, 6], [1382827332000, 7], [1382827374000, 8], [1382827662000, 9], [1382829230000, 10], [1382829230000, 11], [1382829230000, 12]],
        "key": "second"
    },
    {
        "values": [[1382812284000, 0], [1382826522000, 1], [1382826522000, 2], [1382826522000, 3], [1382826522000, 4], [1382826522000, 5], [1382826522000, 6], [1382826522000, 7], [1382826522000, 8], [1382829299000, 9], [1382830207000, 10], [1382830207000, 11], [1382830207000, 12], [1382830207000, 13], [1382830207000, 14], [1382830207000, 15], [1382830207000, 16]],
        "key": "third"
    }
]

I can't get the chart to be displayed though the legend is showing all three labels. Anyway removing (any) two of the series and leaving just one the remaining one gets displayed, so I suppose the problem is not in the data itself but probably something in json structure.

Anyone could help?

Answer 1

I solved the problem: it seems the series must have the same number of elements!
