	When populating a LineChart from a DataTable, is it possible to have the X values of the data points be DateTime values rather than integer or floating point numbers? When I am trying to do this in my application, it appears that the LineChart component is trying to parse them as doubles and Iget a FormatException.

	Indeed, the control can handle only numerical data, although it can display date/times as labels. We will try to implement a version that can display time data as well - it should be ready today or tomorrow and I will upload it here. Until then, you could try converting the time data yourself, e.g. by creating a TimeSpan from the initial time to each date/time value, and passing the TimeSpan minutes or seconds as X values. Stoyan

	As one extension to this new capability, is it possible to specify the StartDate that the XData is referenced to. In some cases I may have a specific date that I want to be at the Y-axis (not just the earliest date in the data set). For example, I may want to show a graph from Jan 1 to Jan 31, even though there are no actual data points until Jan 3. Thanks, -David Deakins

	Sure, our developer is going to add some properties that let you specify the time interval corresponding to an axis. This should be ready in a few days and we'll post the updated version here. Stoyan
