Hi,
Clicking on the marker is throwing "FormatException".The problem occurs in the ExampleBrowser also. To reproduce the problem just open ExampleBrowser -> TimeSpanAxis example, click on any marker. 

Exception details:

System.FormatException was unhandled by user code
HResult=-2146233033
Message=Input string was not in a correct format.
Source=mscorlib

Wrong format string is applied to TimeSpan data. As fast-fix in production code used this:

graphData.TrackerFormatString = "{0}\n{1}: {2:mm\\:ss\\:ms}\n{3}: {4:0.###}";
I was getting same issue on TimeSpanAxis, I had debugged library and found that its not issue with library, rather I was using wrong format string. Later I used below format string and it worked like wow.

{4:%d} Days {4:%h} Hours {4:%m} Minutes

I hope it works.
