[scilab-Users] locate points on curve

[Samuel Gougeon]

Hello Loïc,

You may have a look at the macros of the datatips submodule,
in SCI\modules\graphics\macros\datatips
Parts of them could be useful for your aim.
Noticeably, see the pixDist.sci and orthProj.sci,
in addition to xclick() or locate().

Regards
Samuel
