EjChart control supports 10 types of technical indicators.

Bind data to render the indicator

You can bind the series dataSource to the indicator by setting the specific series name to the indicator by using the indicators.seriesName property.

JAVASCRIPT

$("#container").ejChart({
              //  ...
              //Initializing Series
              series:[{
                  dataSource: chartData,
                  xName: "xDate",
                  high: "High",
                  low: "Low",
                  open: "Open",
                  close: "Close", 
                  //Set name to series
                  name: 'Hilo',
                  //  ...
            }],

            //Initializing Indicators    
            indicators: [{
                //Set Hilo series dataSource to indicator using seriesName
                seriesName: "Hilo",
                //  ...
	     }],
            //  ...
     });

Also, you can add data to the indicator directly by using the dataSource option of the indicator.

JAVASCRIPT

$("#container").ejChart({
            //  ...
            //Initializing Indicators

                   //Add dataSource to indicator directly
                    dataSource: chartData,
                    xName: "xDate",
                    high: "High",
                    low: "Low",
                    open: "Open",
                    close: "Close",                
                    //  ...
	       }],
            //  ...

                       dataSource: chartData,
                       xName: "xDate",
                       high: "High",
                       low: "Low",
                       open: "Open",
                       close: "Close",
                       //Add additional volume field to data source for accumulation distribution
                       volume: "Volume",
                       //  ...
                   }],
               //Initializing Indicators    
               indicators: [{
                     seriesName: "Hilo",
                     //Set indicator type
                     type: "accumulationdistribution", 
                     //  ...
