Playing with Plot Dictionary

What is a Plot Dictionary ?

A plot dictionary is a kind of text file (.plots) which contains a name of a plot along with its equation. The basic idea of dictionary files is to add plots in Khipu without actually typing big equations. User can add the plots based on its name using the dictionaries. We already have some predefined dictionaries which let a user enter some famous plots (i.e. curves and surfaces). User can even download the dictionaries using Internet.


A syntax of a dictionary file follows Analitza syntax. Every line in a file will contain a name and the corresponding equation. For example: A typical dictionary file would have lines as follows:

  • sinus := x->sin x
  • plane1 := (x, y, z)->(x+y+z)-1
Adding your own dictionary file

The flexible analitza syntax would allow the user to create his/her own dictionary file ! User needs to save a text file with .plots extension with correct plot name and equations in each line.
