Adding Line series to XY scatter

[User (Legacy)]

I have a scatter plot with 20 points. Now if I want to add a line series to

that with 4 points my line always gets brought back to zero.

Is there something else that needs to be specified?

Yes. All series have the same number of points, in other words the chart 

data is a grid of values.

What you need to do is "hide" those extra points. You can do this in two 

ways:

1) When you add the new series to the chart, make sure you do:

chart1.OpenData(COD.Values | 

COD.AllocHidden,chart1.NSeries+1,chart1.NValues);

chart1.CloseData(COD.Values);

2) Set the value for the remaining points (from 4 to 19) to Chart.Hidden

chart1.Value[i] = Chart.Hidden;
