[SOLVED] LineSeries with breaks

[Vittorio]

I'm looking for solution to draw noncontinuous graphs.
For example, array of {1,7,*,11,13} should look like in Excel (see attachment)
Would be gratefull for idea how to realize it with TChart.

You must add NaN ("not a number", defined in unit Math) as X or Y value (http://wiki.lazarus.freepascal.org/TAChart_documentation#Skipping_source_items).

Code: Pascal  [Select][+][-]

1. uses
2.   Math;
3.  
4. with Chart1LineSeries1 do begin
5.   Add(1);
6.   Add(7);
7.   Add(NaN);
8.   Add(11);
9.   Add(13);
10.  
11. //or:
12.   AddXY(1, 1);
13.   AddXY(2, 7);
14.   AddXY(3, NaN);  // or: AddXY(NaN, NaN);
15.   AddXY(4, 11);
16.   AddXY(5, 13);
17. end;

Perfect! That's it I'm looking for. Thanks!
