Using JSON formatting with NVD3 charts

Is there a method to transform my JSON data into a format that NVD3 will accept for a multi bar chart? I have a template set up in NVD3 here: http://jsfiddle.net/hohenheim/6R7mu/5/

The JSON data I want to display is as follows:

[{"date": 1396828800, "impressions": 49145385},
{"date": 1396915200, "impressions": 46704447},
{"date": 1397001600, "impressions": 47181000},
{"date": 1397088000, "impressions": 47337965},
{"date": 1397174400, "impressions": 51129266},
{"date": 1397260800, "impressions": 60547397},
{"date": 1397347200, "impressions": 62217077},
{"date": 1397433600, "impressions": 49145385},
{"date": 1397520000, "impressions": 46704447},
{"date": 1397606400, "impressions": 47181000},
{"date": 1397692800, "impressions": 47337965},
{"date": 1397779200, "impressions": 51129266},
{"date": 1397865600, "impressions": 60547397},
{"date": 1397952000, "impressions": 62217077}]

I am struggling to comprehend the sample data being used by the NVD3 chart. Any assistance in converting my data into a compatible format would be highly appreciated.

Answer №1

It appears that the data structure for data5 is as follows:

[
  {key: x, values: VALUES, vAxis: 1},
  {key: x, values: VALUES, vAxis: 1} // and potentially more entries for additional colors
]

The format for VALUES seems to be:

[
  {x: 0, y: N},
  {x: 1, y: N},
  {x: 2, y: N} // with further values for the X axis
]

To match this format, you need to rearrange your data accordingly. It seems like you only have one color source available. How do you distinguish between 

{"date": 1396828800, "impressions": 49145385}
? Is date representing the X axis?

If your data ordering is correct and you are working with a single data source:

data5 = [{key: 'X', values: [], vAxis: 1}]
yourData.forEach(function(el, i) {
  data5[0].values.push({x: i, y: el.impressions});
     // ^ only 1 source/color
                        // ^ incrementing X values starting from 0
});

You may need to make adjustments to the x and y ranges. (Possibly utilizing vAxis in some way?)

Answer №2

After stumbling upon their GitHub page, I can confirm that the answer provided above is indeed correct.

https://github.com/novus/nvd3/wiki/Example-chart-(creating-your-first-nvd3-graph!) The specified data format for charts should follow this structure:

[
    {
        key: "<Series name>",
        color: "<CSS color>",
        values: [
            {x: 0, y: 10},
            {x: 1, y: 20},
            {x: 2, y: 30}
            ....
        ]
    },
    {
        key: "<Series name>"
        ...
    }
]
