    I've got a basic line series chart showing daily maximum tempuratures over a several week period.  I want to display a horizontal threshhold tempurature, say 85 degrees (it's for the summer), so the user can easily see how many days were over 85 and how many under.

    I've considered putting in a dummy series, with a constant of 85 degrees.  I've also considered just creating a silverlight line object and sticking it up over the chart.

    Is there a more elegant way to do this? 

    Thanks!

    Hi Aaron,

    You could use chart's Custom Gridline feature. More about it can be found here:
    http://www.telerik.com/help/silverlight/radchart-features-annotations-custom-gridline.html

    Or you could also take a look at our online demo example:

    Hope this helps.
