Showing two series on a ShieldUI JavaScript Chart having different dataStart properties

I am trying to show some sales data using Shield UI JavaScriptChart. I have currently two series. The one contains data for the year 2012, and the second for 2013. Here is my code:

            dataSeries: [
            {
                seriesType:'splinearea',
                data: [13,25.6,157.2,111.6,112.8,51.58],
                dataStart: Date.UTC(2012, 0, 1),
                dataStep: 24 * 3600 * 1000 
            },
            {
                seriesType:'splinearea',
                data: [17,25.6,147.2,125.6,124.8,55.58],
                dataStart: Date.UTC(2013, 0, 1),
                dataStep: 24 * 3600 * 1000 
            },
            ]

Strangely, the data I get are two tiny stripes in the beginning and in the end of the chart. Why so?

It is quite normal to get that result, since you are specifying two dataStarts where the distance between them is one whole year. What you can do is following: You need to retain the dataStarts being the same; even more I see you have the same amount of points so probably you need to have a point to point comparison. You may also add two collectionAllias properties, specifying that the one series is for 2012 and the other one for 2013:

            dataSeries: [
            {
                seriesType:'splinearea',
                data: [13,25.6,157.2,111.6,112.8,51.58],
                collectionAlias: "Sales 2012",
                dataStart: Date.UTC(2012, 0, 1),
                dataStep: 24 * 3600 * 1000 
            },
            {
                seriesType:'splinearea',
                data: [17,25.6,147.2,125.6,124.8,55.58],
                collectionAlias: "Sales 2013",
                dataStart: Date.UTC(2012, 0, 1),
                dataStep: 24 * 3600 * 1000 
            },
            ]

Using the above code you will be able to represent the sales for the beginnings of 2012 and 2013.
