Dynamic Omnigraph (shareware) http://lib.giveawayoftheday.com/Dynamic_Omnigraph_428520/ The Omnigraph graph processor is an indispensible tool for pupils of all ages. The software enables you to draw lines like y = x 1 either by typing the equation or by just clicking the screen. Graphs and shapes can be transformed and manipulated on screen.

Graph (open source) http://lib.giveawayoftheday.com/Graph_63386/ can draw normal functions, parameter functions, and polar functions. You can use a lot of built-in functions, e.g. sin, cos, log, etc. You may specify color, width and line style of the graphs , and the graphs may me limited to an interval. It is also possible to show a circle at the ends indicating open or closed interval. You can save the coordinate system with graphs as an image on disk either as a bitmap (bmp), Potable Network Graphics (png), JPEG, metafile (emf) or Portable Document Format (PDF). You may also copy the coordinate system into another program, e.g. Microsoft Word, either as a normal image or as an OLE object, which may be edited later by double clicking on it.

Graphs Made Easy (freeware) http://lib.giveawayoftheday.com/Graphs_Made_Easy_697319/ is a software program for creating graphs and charts. It is very simple to use, and you can even import information directly from MS Excel just by copying the cells to the clipboard - and the graph will be created automatically. I think it could be a good solution for anyone looking to create a simple graph or chart quickly and with little effort. Creating a graph is done by picking "New" from the File menu. You will be asked to select the graph type and the X axis values, which can either be calendar dates or numbers. After that you have buttons on the left side of the screen which can add information. You can add as many bars as you want, select any color, create markers, add arrows, text labels and more. A background image can also be added or you can just set a solid color as a background. Another nice feature of Graphs Made Easy is that you can set the image resolution to anything you like, and you can see the canvas size in centimeters or inches. This is especially useful if you want to create a graph of some specific size. Graphs Made Easy is pretty self-explanatory. The program does exactly what the name suggests and I liked its simplicity and quality. ... Publisher description: GME creates graphs and charts with simplified data entry or imported data. It provides powerful editing of parameters, without sacrificing ease of use.

Advanced Grapher (shareware) http://lib.giveawayoftheday.com/Advanced_Grapher_6802/ is a program which helps you calculate complex functions and it creates graphs on a coordinate plane automatically. It is highly useful for students and for scientific work. It supports a multilingual interface; many languages are included with the installation package and others can be easily downloaded. It supports all Windows operating systems and requires a very small amount of your disk space. It plots high-quality 2D graphs for all kinds of equations, functions and tables. It supports many operations like arithmetic operations, logical operations and relational operations. Table values can be directly inserted in the graph or can be easily imported from a text file. Many constants, which are very common in use like PI, are directly available in this software. You can also create many variables for a calculation. It allows plotting up to 100 graphs on one coordinate plane which helps analyzing and comparing many graphs. All the graphs can be seen at the graph toolbar and you can easily hide, delete, and copy a graph from the graph list. Graph properties like its design, equation or table can be set easily. You can also duplicate and copy one graph property to another and abort the calculation of a graph at runtime. «... Publisher description: Powerful but easy-to-use graphing, curve fitting and calculating software. Graphs Cartesian (Y(x) and X(y)), polar and parametric functions, graphs of tables, equations (implicit functions) , inequalities and systems of inequalities and slope fields. Up to 100 graphs in one window. Calculus features: regression analysis, obtaining zeroes and extrema of functions, intersections, derivatives, equations of tangents and normals, numerical integration, value tables, calculator. Lots of graph and coordinate plane parameters. You will be able to create high-quality graphs and copy them to your documents (as EMF or BMP). The program has printing capabilities, multi-document interface, customizable toolbars. Supports English, Dutch, French, German, Italian, Portuguese, Russian and Spanish interfaces.

Wykresy (?) http://lib.giveawayoftheday.com/Wykresy_21358/ is a simple, user-friendly program drawing functions, graphs as well as circles and ellipses. More than 20 function templates provide fast creation of functions. Derivatives and combinations of functions can be easily added. Up to 10 graphs can be seen simultaniously, each of them in color set by user. It is very easy to make an approach and see more details, or browse drawing pad up or down. Graphs can be saved to a BMP file or copied to the clipboard. Program also makes calculations: finds maximal and minimal values, crossing points, and many other. Help in HtmlHelp format is available.
