I set the abscissa became time format:
M_chart1. Series (0). GetXValues () SetDateTime (true);
M_chart1. GetAxis (.) GetBottom () GetLabels () SetDateTimeFormat (HH: mm: ss ");

Abscissa AddXY add point, however, that must be of type Double,
I now of the existing data is shaped as "20:15:08" this time format, there was a way to directly as abscissa drawing?
All I want is a with time change image!

In addition, the scatterplot can modify the size? With round is too large, with small point is too small can't see clearly,

Beg you to help! Thank you very much!
