Winplot is a general-purpose plotting utility, which can draw (and animate) curves and surfaces presented in a variety of formats.
If the program behaves strangely, there is a page of FAQ, which may help. If not, you can e-mail me at the address found in the program’s Help|About dialog box.
Supplementary material (1 Dec 09) This means animations, tutorials, teaching modules, and a font (useful for pi seekers). Donated mostly by Winplot users.
One way to insert a Winplot diagram into a webpage is to create an SVG file.
Follow the links for more information about the Windows 95/98/ME/2K/XP/Vista version or the Windows 3.1 version.

7 Feb: The Anim|Calibrate dialog box is now applicable to every scrollbar in the program. Changes are applied to those scrollbars that are currently open.
5 Feb: Fixed a bug that afflicts files in which a user-defined formula contains spaces. The program should have been removing spaces, but last December it forgot how to. Thanks to a power user for reporting this.
22 Jan: Improved on a feature added in December. The integration results display in the 2D|One|Integration dialog box will now respond to parameter changes in the integrand. Better late than never.
17 Jan: At the request of a user, it is now possible to confine an animation parameter to integer values. This is done by entering a bracketed numerical value for that parameter, using its individual dialog. Integer mode is turned off in the same way --- by entering a value enclosed in brackets.
13 Jan: I just fixed an obscure but interesting glitch, which appeared in early December when I introduced my new derivative syntax. An alert observer pointed out that this syntax was failing when applied to the evaluation at x = -1 of the derivative of x^4. Indeed it was, but it would not have failed if the source function had been written pow(4,x) instead; the difficulty was the program’s use of logarithms for exponential creations. I had forgotten to teach the new deriver to check for integer exponents (as the rest of the parser does) and skip the logarithms when they were not needed. Now that the check is in place, the problem seems to have disappeared.
9 Jan: A user wrote to say that it would be useful to have a button in the 3D Slicer dialog box that added tangent lines to the diagram. I agreed, and the new version is ready to try.
4 Jan: As recommended by a power user, I modified the system of attaching “anchors” to Points in 2D and 3D. Details of the syntax are found in the Help texts for the Equa menus. A minor bug was also fixed, which was keeping tangent planes from responding dynamically to changes in the surfaces they are attached to.
