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 (29 Jun 09) This means animations, tutorials, teaching modules, and a font (useful for pi seekers). 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.

29 Jun: Responding to a suggestion, I modified the “table” feature in 2D, so that it displays the coordinates of an active web diagram when one is on the screen. A new source of useful examples has been contributed by a power user.
26 Jun: Fixed a bit of sloppy code that may have been causing sporadic crashes after items were deleted from the Inventory.
20 Jun: During a recent update, I inadvertently disabled the attach-text-to-a-point feature. It has been enabled again. Thanks to a power user for reporting this.
6 Jun: The first unintended consequence has appeared (3D files that include implicit surfaces would not open without crashing), and it has been repaired. (There is nothing wrong with the files.)
25 May: At the request of two users, the graphing of vector fields in 3D is now enabled. Lots and lots of vectors.
16 Apr: Fixed a minor glitch --- after simulprinting multiple images on a single sheet of paper, the program was hiding the graphing window, forcing the user to re-open the original file.
24 Mar: Added a new function constructor --- ifpos(f|v,g) returns f if v is positive, and returns g otherwise. Also fixed a few minor glitches.
18 Mar: At the request of a user, I added inflection points to the list of Extremes in 2D windows (these are points where y' is extreme).
11 Mar: Attended to an assortment of glitches. A user reported trouble when retrieving diagrams with inserted text items, and I discovered that the “evaluated text” feature (introduced in June of 2006) was producing some unintended consequences for ordinary text. During the investigation, I also discovered that 3D file retrieval was not always centering the original diagram, and that the program was occasionally miscalculating the “box” that encloses a 3D curve. Finally, the 3D Btns Help now has an explanation of what it really means to position text “with respect to the figure.” Sorry for any inconveniences.
17 Feb: It turns out that I did not get the last change quite right! A user reported some misbehaving buttons in the Inventory. I think that the problem has been fixed; sorry for the inconvenience.
15 Feb: A user requested that the shading of implicitly defined regions in 2D allow the viewing of individual regions. That dialog box has been revised accordingly. A different user reported that the 2D Translate feature was giving inaccurate results when applied to joined functions. I think that the problem has been fixed.
2 Feb: Finished the job that I announced was finished on 26 Jan.
26 Jan: At the request of a user, the display of individual component functions of recursively defined sequences has been enabled, using the miscellaneous Other|DEq windows. I also fixed a couple of minor bugs in the table windows.
17 Jan: The Hungarian version has been updated.
14 Jan: A power user made several suggestions to enhance the performance of the Mapping windows.
