EJSC.TrendSeries

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" }

               );
