TDBChart - highlight certain points ?

[LucieLastic]

hi

I've written a program that looks for spikes in the data. Using a TDBChart (line graph), is it possible to highlight certain points on the graph by say, specifying either a value index or the actual x,y field values?

I've managed to do a sort of work around.

Main query feeds series[0]. 2nd query is filtered to show the spikes found and datasourced to series[1]. Series[1] is superimposed onto series[0].

Series[0] is a line graph and Series[1] is set to a 'point' graph (little blocks).

This seems to work, not sure if its the best way though.
