[SOLVED] LineSeries with breaks
«
on:
October 23, 2017, 10:29:26 pm »
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]

with

do
begin
Add

;
Add
(

;
Add
(

)
;
Add
(

)
;

(

;
//or:
AddXY

// or: AddXY(NaN, NaN);
AddXY

;
AddXY
(

end
