[edit] Summary

All analysis tools from previous versions have been replaced with new tools in Origin 8 and later versions. The new tools support Themes and scripting and are based on X-Functions.

To get help with any of the new X-Functions, use :

X-FunctionName -h;
help X-FunctionName;

For example,

nlfit -h;
help nlfit;
