GraphSight Junior

Now what would you use to produce a simple graph on your PC? Opportunities vary from pen and paper to huge applications like Excel, but we wouldn't really start learning advanced Excel features just to draw a simple graph and it would be far too tiresome to draw the graph yourself and then scan it. Use GraphSight Junior.
GraphSight Junior is a compact application that lets you draw any two-dimensional graphs in the Cartesian coordinates system. This program has the simplest interface for graph generators: just type in your formula, pick the color and thickness of the line and there you go - it's already on the screen. There are also interactive graphs - check the enclosed examples and help file.
The tool, alas, doesn't allow you to print out graphs, although there is a way to do it - export it to BMP first and then proceed as usual. The program requires registration (it's free but obligatory) and frequently displays nag screens until you give in and do register your copy.

GraphSight Junior is an easy to use freeware handy 2D math-graphing program. It was originally designed to help students and teachers satisfy their day-after-day math plotting needs. It makes it easy to plot and explore common Y(X) = F(X) Cartesian graphs, set text labels on the coordinate plane, zoom or shift a graph with just a single click & move of mouse. The resulting picture can be than exported to a file or windows clipboard as a bitmap.
Originally GraphSight has come as a realization of the idea "A graph does not have to be dead!". This is gained through the interactivity of every graph on a coordinate plane. All of them react to mouse or keyboard input, each of them have its own shortcut menu, remembers all the formulas you enter for it, can be displayed using different styles, colors and sizes and much more.
