Hi Louis,
You need to specify that the line is in XY Scatter mode (from the
series options). After you do that go to Value Grouping and assign the X value property which should be the date/time associated with each line data point. That way the line will also have date information - currently when you switch to date time numeric axis the line still uses categorical X values - 0, 1, 2 etc.In the case of the .NET date time format 0 maps to
1899 that's why you get dates around 1900. For example check out the Technical Price Indicators example where the line
series is switched to XY Scatter.
Hope this helps - let us know if you meet any problems or have any questions.
