Change Line color with Condition

Hi,

I want to ask if it is possible to change the line color of a line/spline chart when it hit a high or low value?    For example, my data ranges average from numeric value between 50 and 120.  So for value of below 50, I would like the line color to be orange and for value above 120 the line color is red.

Thank you.

Hi Albert, 

 

Thanks for contacting Syncfusion products. 

 

We have prepared a sample for your requirement by overriding the onDraw() method of line segment. Please find the attached sample from the below location.

Hi,


Thanks for the sample code.  The line color came out but the spline graph now looks like a line (no more smooth curve).  How do I achieve that?  Thank you.
