Description Paul Field 2022-03-31 10:55:58 EDT 
Hi,   I'm trying to use TDrawLine to draw lines on timestamped TDateTime data.  The TDrawLine class X0,Y0,X1,Y1 points are single types whereas TDateTime is double therefore results in massive lose of resolution.  Can only draw lines to the nearest 5minutes whereas I need sub-second accuracy.
