Plotting Xively timeseries data using Rickshaw

Xively (formerly Cosm, formerly Patchube) now has a Javascript library for their API. I have been meaning to learn the Rickshaw library for awhile as it comes highly recommend from several people. It turned out to be a doddle to use. I just mixed in the moment.js library to do some date munging and was able to knock up some graphs in an hour or so.

These two data source aren’t pumping out data anymore but you can see an example here.

    Hi Jason!

    Great post! Thanks a lot for sharing! I improved a little bit on your idea and built this generic Xively feed viewer: http://www.sarfata.org/xively-viewer/

    Still working on it but it is already much better than Xively dashboard 😉

    cheers!

    Hey Jason,

    I am new to Xively data retrieval and I am still trying to get my head around it. However I can’t seem to view the live versions of your graphs. Am I missing something?

    Cheers

    Hi Jason,
    xively-rickshaw is awesome stuff. I am plan to use for historical data for my RPi weather station project.

    Question: Line Graph chart seem to show 0 at minimum, even if the minimal data point is 30 (for example). Is there a way to set chart minimum other than 0?

    Best,
    Jay

      Here is example of what I was referring to: http://mygardenspy.com/historical.html

      Also, if there is a certain credit/link you would like on my page (since I heavily used your xively-rickshaw I am happy to do so.)

      Another oddity I noticed is if I do a pull at the interval for 3 months or 1 year I just get a graph spanning the time data points exist, just at the smaller sample size. Might be nice to represent the entire duration in the x-axis. Perhaps such a way exists, I just need to look closer at my setup. Maybe this also becomes a non-issue when my data set actually spans the time of the historical queries (which it does not yet.)

        Hi Jay,

        Glad it was helpful & thanks for the credit/link. You can set minimums for the graph y axis (as documented here https://github.com/shutterstock/rickshaw#rickshawgraph) using the min param when you initialize the graph.


        var graph = new Rickshaw.Graph( {
        element: document.querySelector("#chart"),
        width: 640,
        min: 100,
        height: 400,
        renderer: 'line',
        series: [
        {
        data: data,
        color: '#6060c0',
        name: unit
        }
        ]

    Would it be possible to explain how to simply add more than one Channel to a single graph?
