Hi Mirfan,

Thank you for sharing your solution with other community members !

Ok, I guess I have found the solution. May be it help for someone, so solution is to select "dataSource" of trend series explicitly when defining Trend.

It solve my problem.

Thank you.

Hello Hristo, Thank you for your message. Yes I am generating separate series for Trends and x-axis type is CategoryX. My Data Object have following properites; var obj = {}; obj.Date = date; obj.Close = 12.2; obj.High = 14.5; obj.Low = 10.1; obj.Open = 10.7; obj.Volume = 12231; obj.Price = 12.5; //use for line series Now you can put loop from 0 to 100 and generate value for all above properties....then in next loop, only generate value for "Price" & "Date" and leave other properties as NaN. Here are the code snippet for generated Trends: $("#chart").igDataChart("option", "series", [{ type: newIndicator, showTooltip: false, name: newIndicator, title: indicator, xAxis: "xAxis", yAxis: "yAxis2", closeMemberPath: "Close", highMemberPath: "High", lowMemberPath: "Low", openMemberPath: "Open", volumeMemberPath: "Volume" }]); NOTE: We have added all possible trends in DropDown so whatever user select we add it...so "newIndicator" is the selected value/Trend.
