Overcoming DateTime Precision Issues in the XamDataChart (splines turned on).

Our team has a hard requirement to support graphing down to the nanosecond resolution. This is not supported by the .NET DateTime struct. We are building a wrapper around the DateTime class to fix the precision problem (PreciseDateTime). 

Now the only element left is how can we interface the chart with PreciseDateTime? We are currently using a CategoryDateTimeXAxis with SplineSeries'. One solution was to utilize the NumericXAxis instead, but this leads to a goofy spline result (because of the ScatterSplineSeries implementation).

The spline comparison is shown in the attached demo project. If we can get the behavior of the first chart (CategoryDateTimeXAxis) within the NumericXAxis this could simplify our implementation. If not, other ideas and suggestions are welcome.

Thanks for the time.

    Hi Will,

    Currently there is no built in interface that allows modifying the interpolation algorithm. You may consider logging a new product idea at
    Steps to create your idea:
    1. Log into the Infragistics Product Ideas site at (creating a new login if needed).
    2. Navigate to the product / platform channel of your choice (e.g. WPF, Windows Forms, ASP.NET, HTML5 / Ignite UI, iOS / NucliOS, etc.)
    3. Add your product idea and be sure to be specific and provide as much detail as possible. Explain the context in which a feature would be used, why it is needed, why it can’t be accomplished today, and who would benefit from it. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. Be convincing!

    The benefits of submitting the product idea yourself include:
    - Direct communication with our product management team regarding your product idea.
    - Notifications whenever new information regarding your idea becomes available.

    Additional benefits of the Product Idea system include:

    - Ability to vote on your favorite product ideas to let us know which ones are the most important to you.  You will have ten votes for this and can change which ideas you are voting for at any time.
    - Allow you to shape the future of our products by requesting new controls and products altogether.
    - You and other developers can discuss existing product ideas with members of our Product Management team.

    The product ideas site allows you to track the progress of your ideas at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.

    The following forum thread provides some useful information about creation of custom scatter series if you need to inherit from the deafault series and modify the interpolation
