I believe there are a few windows emulators/integrators for the Mac OS If you have an Intel processor.
The only free one I found is from http://www.opensourcemac.org/ but seems a little risky..you need to be a bit of an expert The Incredible charts reference material is still great Look Up FCharts SE for an alternate free charting software

again its for windows but..................... Can I run FCharts on a Mac or on Linux? FCharts is a native Windows application, but users have reported success running FCharts using Wine on Linux, or Darwine on OSX. It will also run perfectly under emulated virtual machines in VMWare, Virtual PC, Virtualbox and other VM emulators.
