MathGV is a mathematical function graphing software program for Windows XP, 2003 and Vista. It can plot 2 dimensional, parametric, polar, and 3 dimension functions. MathGV contains no spyware, adware or similar problematic features. After years of using clumsy scrolling command line oriented math programs in college, I decided to write a math program with the interface that I wanted. The MathGV interface is dialogue driven and allows changes to any setting at any time with immediate results. This instant visual feedback makes mathematical functions much easier to understand. I'm considering releasing the next version under an open source license.

MathGV Features:
1. Plots 5 function types; 2D Cartesian (X, Y), parametric, polar, 3D Cartesian (X,Y,Z), 2D function rotated into 3 dimensions.
2. Graphs can contain multiple functions.
3. All graphs are drawn on resizable bitmaps, and displayed in scrolling windows.
4. Graph bitmaps can be copied and pasted into other programs, or saved to disk.
5. Multiple document interface (MDI) allows for simultaneous viewing of multiple graphs.
6. Can calculate negative numbers to fractional powers.
7. Function calculator that can give decimal or fractional results.
8. All changes take effect immediately after they are made.
9. Use tool bar buttons to zoom, rotate, and page up, down, left, right.
10. Graphs can be saved in bitmap (bmp), jpg or MathGV format.
11. Label tool bar for drawing, lines, free hand lines, rectangles, circles, round rectangles, flood fills, and text.
12. Labels can be selected, dragged, dropped, resized, added and deleted on any graph at any time.
13. All graphs are drawn by off screen threads. This prevents the program from "hanging" while plotting complex graphs.

A Typical Graph Design Process
The steps to designing a graph can be done in an infinite number of different orders. The following steps might be used to design a typical graph.
1. Create A New Graph - Use one of the three "File / New" menu items to create to create a new graph of the desired type. Graph types are: 2 dimensional Cartesian, polar, and 3 dimensional Cartesian.
2. Resize Graph Bitmap - Use the "Graph / Bitmap Size Colors " menu item to adjust the size of the graph's bitmap drawing surface.
3. Add Functions - Use the "Function / New" menu items to add functions to the graph.
4. Zoom, Rotate, Scroll, or Page Up, Down, Left, Right - Use the graph tool bar or hot keys (F2 - F12) to easily manipulate the graph's view close to the desired view.
5. Fine Tune The Graph's View - Use the "View / Change View " menu item to get a more precise graph view (Zoom, Rotate, and Page settings).
6. Change Graph Setting - Use the "Graph / Graph Settings " menu item to make changes to the visual background attributes of the graph.
7. Add Labels - Use the "Label / Show Hide Label Tool Bar" menu item to display the label tool bar which allows labels to be added to a graph. For more information see: Adding Labels to a Graph.
8. Print, Save, or Copy to Clipboard - The final step is to do something with the finished graph. Graphs can be printed, saved to disk, or copied to the clipboard for use in another program.
