Grapher.app versions 1.1 & 2.2

Question

Pour les amateurs de mathématiques et sciences,
  “Grapher.app“ est dans les utilitaires des applications *de Mac OS X 10.4 & 10.7 ; c'est un très intéressant logiciel traceur de graphes mathématiques et éditeur d'équations, dont l'aide beaucoup trop succinte ne dévoile qu'une petite partie des possibilités. Une notice plus complète de 78 pages en langue française, illustrée de copies d'écran et débutant par une initiation progressive, est téléchargeable gratuitement sur le site :

  En pièces jointes : une fiche de présentation du "Mode d'emploi Grapher" (nouvelle édition du 01/12/2011) et le sommaire de ce manuel. Impossible !
  Cordialement, YB24
For persons interested in mathematics and sciences,
  “Grapher.app“ is an Application Utility of Mac OS X 10.4 & 10.7, it is a very interesting graph plotter software and math equation editor, but Grapher's Help is a lot too brief and reveals only a small fraction of its possibilities . A more complete MANUAL of 78 pages in ENGLISH, illustrated with screen captures and starting with tutorials, is downloadable free on the website :
<http://y.barois.free.fr/grapher/>
  Attachments : a presentation of “Instructions for Use - Grapher“ (new edition 12/1st/2011 and the table of contents of this manual (English language). Impossible !

  It is not advertising : my website is not commercial nor for advertising, nothing to sell, nothing to be paid. I created it and wrote a manual for Grapher, only because Apple's Help of Grapher is very poor compared with Curvus Pro's one.
  The second reason is the great number of bugs created by Apple when Curvus Pro became Grapher, 19 of them still alive in the last version 2.2 of Grapher. They are listed in the manual with their remedies.
  Shall I congratulate Apple's developers for that ?
  I try to help Grapher users and lovers. All stuff on my website may be used free by everybody, there is no copyright, it's free of charge.
  Did you inspect the website before you criticize my post ?
Thanks Apple and Host for not helping Grapher users.
