when rendering chart with a single line series i get exception - Value cannot be null. Parameter name: value. 

However i only get this exception on iOS, while works fine on android.

I have included the exception and stacktrace in attachment.

I cannot determine the reason or the origin of this exception.

Regards Gjorgji.

Issue resolved.

The problem was setting font family on ChartTooltipBehavior.

The confusing thing was that exeption is only thrown on iOS while it works fine on android.
