The TrendSeries is rendered as a line based on the results of a function applied to the related series' data points.

The constructor expects a reference series, a trendType and an optional set of object properties.

The trend series then “trends” the data in that referenceSeries according to the trendType into a function, and plots the function in the visible area of the chart.

Constructor

       EJSC.TrendSeries( EJSC.Series referenceSeries, string trendType [, object options] )

Valid options for trendType:

       "linear"

       "power"

       "exponential"

       "logarithmic"

Example

var mySeries1 = new EJSC.ScatterSeries(...);

var mySeries2 = new EJSC.TrendSeries(

       mySeries1,

       "linear",

       { title: "New Trend Series" }

);

Defining Properties and Events

TrendSeries properties may be set individually after the series has been created or in batch using the options parameter during instantiation.

Setting properties individually

       var mySeries = new EJSC.TrendSeries(myDataSeries, "linear");

       mySeries.lineWidth = 2;

       mySeries.title = "New Trend Series";

Setting properties in batch

       var mySeries = new EJSC.TrendSeries(

               myDataSeries,

               "linear",

               { lineWidth: 2, title: "New Trend Series" }

       );
