How can I add custormized lines on series line chart?

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.

Hello,

It seems that something went wrong with the attachment. Please attach the image as a PNG file. As for the 3D line chart - you can take a look the following example in our Windows Forms demo application:

All Examples > Chart Gallery > Line > XYZ Scatter Line

Thanks for you reply.

I checked that you asked me but the graph I want to make should be 3D and multi series with maker on each point. And each point should have line across series data so I can see the movement. I attached the image file again. Could you look this one?

Hi Support team,

I mixed mesh and line graph together to display the graph I wanted but it has some problem.
There are some null values which shouldn't be displayed on the graph but it looks not possible for me.
I want to skip to display which is null value on mesh and line graph.
Is it possible?

I attached two image files I captured.

Best regards,
Kevin

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:

Thanks that was what I wanted.
I have one more question.
Can I change one specific marker's color in data series?
I want to change the color of the marker of data point if the value changed upward or downward.

Thanks.

Yes, you can set individual marker styles for the series data points:

NMarkerStyle marker = new NMarkerStyle();
marker.FillStyle = new NColorFillStyle(Color.Orange);
series.MarkerStyles[n] = marker;
