The Plug-In version of WEBPlotter is based on the Netscape Plugin Application Programming Interface.

The ActiveX version of WEBPlotter is based on the ActiveX technology.

See the WEBPlotter page and the above links for more details.

The ActiveX version of WEBPlotter is available also for developers (with predefined API functions and properties), however it is available only on demand and for projects, which cannot be competitive with my software. So if you want to test it, you should first contact me.
