.....ongetpointerstye behaves of valueindex does not count null data. eg. if series values are 0..100, but all odd indexes are null, then ongetpointerstyle only gets activated for 50 of the 0..100 points, those that are not null. Is that correct?

I can control the size of the points with with chart.series[0] as tlineseries do Pointer.Size:=vesselshotsize.Value; However, the point size of the symbol shown in the legend also tracks this, so if my point size is 1 you can't see ...
