Problem 2: If I try to use UIColor.Gray an exception is thrown. I solved this using UIColor.FromRGBA (161, 161, 161, 255) instead.
Problem 3: The gauges don't look really pretty in iOS. Is there any way to make them look like the Android/Phone versions?
The code is similar in windows phone, but replacing Color types with the appropriate ones.
Thanks!
