I have a stacked bar chart. Lets say the values for one stack are
Y1,Y2,Y3. If Y3 is zero, there is still a thin line plotted at the top
of the stack to represent it, which looks  abit messy. Is there any
way of saying don't plot anything for a zero value?

Fixed in trunk (r52531). If you don't use trunk you can update your
version easily:
Open file (lazarus)/components/tachart/taseries.pas.Seek "procedure
BuildBar;" - it should be near line 1000.Near the bottom of this
procedure there is a comment "// Draw a line instead of an empty
rectangle".Remove the following two lines "if Bottom = Top ..." and
"if Left = Right..."Recompile the package tachartlazaruspkg.lpk.
