I want to add customized lines on series line chart.
The chart I want to make will be refreshed every 10 seconds with 3D mode.
Customized lines should be added on all the values across all line series.
To make it simple, I want to add some lines on 3D series line chart using x y z coordination or y values and series information.
It's little bit difficult to explain what I want to do so I attached an image file.

Hi Kevin,

To set a empty data point you have to set DBNull.Value or Double.NaN as a data point value. Please take a look at the following example in our Winforms demo application:
