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#Skippi
ng_source_items).

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i uses 
Math; with Chart1LineSeries1 do begin   Add(1);  Add(7);  Add(NaN); 
Add(11);  Add(13); //or:  AddXY(1, 1);  AddXY(2, 7);  AddXY(3, NaN);
 // or: AddXY(NaN, NaN);  AddXY(4, 11);  AddXY(5, 13);end;
