procedure AddHighLowValues(Src: TVec; Offset: double; Step: double);
Use this method to pass values to the HighLow series when the drawing is mode is overview.
Result: stored in self (calling object)
Remarks:
The offset defines the start on the X axis and the step the distance between consecutive samples on the X axis. The src should contain the data that is to be drawn. For THighLowSeries there should be one high and low value for each x value. The two Y values must be interleaved: ((y[0], y[1]), (y[2], y[3]), (y[4],...),..)
