Replace old Tchart

Is it possible to replace the old delphi5-6-7 Tchart with the tms Advanced Chart?

is all compatible or i most rewrite my code?
thanks everbody

The oldest version of Delphi that TMS Advanced Charts still supports is Delphi 7.
TMS Advanced Charts was not designed as an interface compatible replacement for TeeChart. The focus of the chart was on specific features that are not in TeeChart.
