Hi Seung,

Do you mean you would like the data3 to be not connected?

If this is the case, please use NoValue for the missing points. For example:

data3:    1      NoValue      2     NoValue       NoValue     3      NoValue

Note: The syntax of NoValue depends on your programming language. It is called Chart::NoValue in C++, $perlchartdir::NoValue in Perl, Chart.NoValue in .NET (VB.NET, C#) and in Java, cd.NoValue in VB6/VBScript/ASP and ColdFusion, ChartDirector::NoValue in Ruby, and just NoValue in PHP or Python.

If you want the line to join through the missing point, please use the LineLayer.setGapColor method and set the gap color to SameAsMainColor. For example, in C#/Java:

layer.setGapColor(Chart.SameAsMainColor);

Hope this can help.

Regards
Peter Kwan
