Un éditeur de texte dédié aux mathématiques

Mathpad is an easy to use text editor for mathematics. You can mix together ordinary text and any mathematical expression. Ideal for math teachers to create quizzes, tests and handouts. Also, you can save the formatted text as an image. With most equation editors you choose a template with the mouse, type a few keystrokes and repeat the process. Mathpad doesn't work this way. Mainly, you just type characers at the keyboard.

It draws a diagramms from your txt-data files.
It scales your diagramms automatically or manually.
Simply make a txt or csv (ASCII) file like that:

Dow Jones
Date; Open; High; Low; Close
4.14.2005; 10403.71; 10457.06; 10248.23; 10278.75
4.15.2005; 10276.61; 10311.26; 10059.36; 10087.51

Run VIGraph and open that file. You will get a diagramm with 4 colored lines (for Open; High; Low; Close).
