-
- Version 0.90, September 1990
-
- Initial Release. First "Beta-test" version.
-
-
- Version 0.91, October 1991
-
- Added PCX file import capability. ZGRAFWIN can now import mono,
- 16-color, and 256-color PCX files. Scroll bars have been provided
- to make it easier to scroll graphics images onscreen. Hope to have
- PCX export capability soon!
-
- Improved G(X,Y) graph a bit. Also, user can now MANUALLY specify
- the (x,y) data range for X-Y Line Graphs, and the y-range for Bar
- Graphs, since the automatic-scaling feature is not always
- desirable...
-
-
- Version 0.92, October 1991
-
- Added monochrome PCX file-save capability. Hope to have 16-color
- PCX saves available in next major release of the program. Added
- crosshatch-fill options for pie, bar, and area graphs, which may be
- useful for graph printing. Added some very basic online help.
-
-
- Version 0.93, October 1991
-
- Cleaned up pie graph appearance.
-
-
-
- Version 0.94, November 1991
-
- Added the full-screen editor.
-
-
-
- Version 1.0, November 1991
-
- Added the ability to save graphics images in 16-color PCX format.
- Getting the 16-color PCX code running under Windows was an absolute
- nightmare, but it's working now (thank God!).
-
- I've also added the ability to place up to 30 text strings, each up
- to 80 characters long, on graphs.
-
- This version marks the first official, "non-beta" release of
- ZGRAFWIN. I hope you like it!
-
-
- Version 1.1, November 1991
-
- Added ability to graph "non-functions" like circles, ellipses,
- etc. in the x-y plane (see documentation). Fixed a few bugs.
-
-
- Version 1.2, January 1992
-
- Added ability to perform Direct-GDI printing, making for
- better-looking graphs.
-
-
- Version 1.3, January 1992
-
- Added ZOOM and Expand/Reduce-view feature for F-2D and X/Y Line
- Graphs. The vertical and horizontal scroll arrows may now be used
- to move the relative position of the graph on the screen for these
- two graphs. Made the character-font for graph titles a bit larger,
- for better viewing. Cleaned up a few more bugs.
-
-
- Version 1.4, February 1992
-
- Added ability to graph up to 4 separate curves on F-2D graph.
- Improved printing of graph titles.
-
-
- Version 1.5, March 1992
-
- Improved appearance of X/Y, area, and 3-D bar graphs.
-
-
- Version 1.6, March 1992
-
- Reworked online help. Program now uses the regular Windows help.
- Added a demonstration program, DEMO.EXE.
-
-
- Version 1.7, March 1992
-
- Fixed some small bugs.
-
-
- Version 1.8, March 1992
-
- Spruced up the demo program a bit.
-
-
- Version 1.9, April 1992
-
- Added ability to change foreground and background colors using the
- arrow keys.
-
-
- Version 2.0, April 1992
-
- Fixed a nasty bug which prevented using the [Enter] key to complete
- a dialog box entry. Interestingly, the problem appeared when
- testing under Windows 3.1--it seemed to work OK under Win 3.0.
-
- Added ability to save program configuration settings; the file
- "ZGRAFWIN.CFG" is now used for this purpose.
-
-
- Version 2.1, June 1992
-
- Added ability to color in graph regions by clicking the left mouse
- button inside the region to paint. The right mouse button now
- brings up a dialog box allowing the user to set/change the paint
- color.
-
-
- Version 2.2, June 1992
-
- Improved the graph data-entry for most of the graphs. Entering
- data values for the Pie, X/Y, Log, Area, and Polar graphs is now a
- lot quicker and more intuitive, using "spreadsheet-like" screens.
- The bar graph data-entry could still use some work, though, and
- hopefully will be improved in the future.
-
-
- Version 2.3, June 1992
-
- Improved color options. User can now select from a palette of 64
- colors. Blasted away at some more bugs...
-
-
- Version 2.4, July 1992
-
- Made the bar graph data-entry screen consistent with the other
- "spreadsheet-like" data-entry screens.
-
-
- Version 2.5, July 1992
-
- Reworked the pull-down menu structure into a simpler, more
- consistent interface.
-
-
- Version 2.6, July 1992
-
- Made the left-mouse click-to-paint feature "toggleable", to prevent
- accidental graph paint catastrophes. Fixed the clipping rectangle
- on the X/Y graph so that when displaying graphs that have points
- which fall outside the graph boundaries (manual scaling option) no
- points will be shown.
-
-
- Version 2.7, August 1992
-
- Added a "printer setup" option; this function now calls the actual
- Windows printer driver setup program, much like the Windows Control
- Panel does. Adding this feature was fun because I didn't have to
- write the code myself--it was already in Windows. Yup, a lot of
- the stuff you need is already out there waiting, if you can just
- figure out how to "tap into" it...
-
-
- Version 2.8, Aug. 1992
-
- Modified the X/Y, Log, Polar, and Area graphs so they can now
- display graphics symbols as well as regular ASCII symbols to
- represent the data points on the graphs.
-
-
- Version 2.9, Aug. 1992
-
- More bug fixes.
-
-
- Version 3.0, Sept. 1992
-
- Ahem. Uh, more bug fixes.
-
-
- Version 3.1, Oct. 1992
-
- Added a feature to allow the user to specify the number of
- divisions along the x- and y- axes on some of the graphs. The
- relative precision of the numbers displayed along the axes can now
- be specified also.
-
-
- Version 3.2, Oct. 1992
-
- Added the Tool Bar.
-
-
- Version 3.3, Oct. 1992
-
- Put Some More Selections on the Tool Bar.
-
-
- Version 3.4, Nov. 1992
-
- Completely reworked the area graph. It looks more like a "ribbon"
- graph now, with a more professional 3-D look.
-
-
- Version 3.5, Nov. 1992
-
- Added a "Print" Tool Bar button for Printing Graphs.
-
-
- Version 3.6, Dec. 1992
-
- Fixed a problem in Text-Field printing output.
-
-
- Version 3.7, Dec. 1992
-
- Spruced up some of the hatch-fill patterns (useful for black-and
- white printing).
-
-
- Version 3.8, Aug. 1993
-
- Fixed a bug in the color palette display.
-
-
- Version 3.9, Sept. 1993
-
- Changed interactive paint button from left-mouse to right-mouse.
- Paint color selection is now on middle mouse button, and/or can
- be adjusted under "Options/Colors/Paint Color". Added ability
- to save graph data files (new toolbar button). Added ability to
- record number of graph axis divisions and significant digits
- displayed along graph axes in these files.
