Winplot for Windows 95/98/ME/2K/XP/Vista (708K) (23 Apr 08)
Click the above link to download the program.
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 (12 Aug 07 ) This means animations, tutorials, teaching modules, and a font. Donated mostly by Winplot users.
Follow the links for more information about the Windows 95/98/ME/2K/XP/Vista version or the Windows 3.1 version.

23 Apr: A user pointed out that the program was not sizing points (bullets and circles) correctly when placing a high-resolution copy on the clipboard. That has now been fixed.
19 Apr: In response to user requests, there are three new features. (1) Overcoming my aversion to dynamic level curves, I installed a 3D level-curve demo that applies to surfaces of the explicit type z=f(x,y). It seems to work ok, but I am keeping my fingers crossed. (2) The “evaluated text” feature has been enhanced by allowing texts to alternate static and evaluated sections; the program has been taught to treat the character “~” as a separator between the two modes of interpretation. (3) The “time” parameter @ can now be brought to a scheduled stop, as in Wingeom.
30 Mar: The program was not correctly opening 3D files that contain animated tangent planes, or that were saved with the Cube viewer activated. I think the problem has been fixed (there is nothing wrong with the files themselves).
22 Mar: Polynomials had not been enabled in the 2D|Two|Combinations dialog box; now they are. The calculation of polynomial second derivatives was causing crashes; that has also been fixed.
9 Mar: As a convenience to the user, the Two|Volume of Revolution dialog now allows any axis that is parallel to a coordinate axis.
6 Feb: A few improvements and repairs. A user pointed out some misshapen arrowheads in 2D windows whose corners had been set by the View dialog. Another user pointed out that the arg function (in z-plane Mapping windows) was not behaving properly. Some detective work revealed that I had inadvertently created this error while working on jump discontinuities last June. I also improved the PiCTeX treatment of solid arrowheads.
2 Feb: Tinkered with the behavior of the numeric scale on the axes during a Zoom In, and made some minor changes to the Mapping windows.
27 Jan: At a user’s suggestion, improved the response of the up- and down-arrows in 3D. The program no longer makes the user work so hard to move the observer position away from the z-axis. The 3D program also now responds better to surfaces whose equations produce unbounded coordinates. Please report any unintended consequences.
14 Jan: A user reported that the domain-restriction check for 2D implicit curves was appearing automatically (uninvited) during an editing session. Should be ok now.
13 Jan: Made some slight improvements in the accuraracy of the hidden-line removal in 3D windows.
11 Jan: Left a tool in the patient after the operation on 9 Jan, which affected 3D implicit graphs adversely; the tool has now been removed.
9 Jan: The domain of an implicit 2D curve can now be restricted by a supplementary inequality. The PiCTeX output for arrows has been modified so that it can be edited more easily by the user.
