About KyPlot (this is the 32 bit version. the 16 bit is also mentioned below)
KyPlot is designed to analyze numerical data and create graphs and schemes.
It is particularly suited for scientists who would like to make precise and refined graphs.
You can also make colorful schemes for presentation with KyPlot.
KyPlot is a Windows application and is available as 16-bit or 32-bit version.
The 16-bit version runs in Windows 3.1, 95/98/Me and NT3.5 or more and the 32-bit version runs in Windows 95/98/Me and NT4.0/2000.
Even with the 16-bit version you can use long file names in 32-bit Windows.
Standard version and fast code version are available as KyPlot 32-bit version.
The fast code version is compiled with fast code option and ~3-fold faster in numerical computation than the standard version.
But it has almost no improvement in drawing speed and its exe file is ~3-fold larger.
The fast code version is recommended for those who want to do time-consuming calculations such as nonlinear optimization
KyPlot consists of "spreads" for processing data and "figures" for drawing graphs and schemes.

* Axis breaks can be set to X and Y axes.
* You can customize attributes of individual data symbols, axis ticks and axis labels.
* Legends, data labels can be created, as well as calibrations for time series data.

Drawing tools
--------------
* In figuresheets you can draw lines, B-spline curves, ellipses, and boxes using mouse as in other drawing applications.
* In addition, you can place objects by specifying the size and location as in CAD programs.
* In text editing mode, you can set superscripts, subscripts and variable line heights as in a word-processing application.
You can put mathematical formulas as well.

Although an on-line help file is provided, it is still incomplete.
Please refer to the sample files in "KYPLOT/SAMPLES" folder to learn how to use KyPlot.

File formats
--------------
The files created by 16-bit version and those created by 32-bit version are in different formats.
32-bit KyPlot version 2 supports 32-bit version 1 files, but does not support 16-bit files.
16-bit files have to be imported into 32-bit KyPlot version 2 using 32-bit KyPlot version 1 and then saved as 32-bit version 1 files.
------------------
Customizing KyPlot
------------------
Open "Preferences" window by clicking "File/Preferences" menu.
Click "Save" button to save the settings you changed as defaults.
When you want to cancel all the customized settings,delete the "kyplot.ini" file in Windows directory.
The following is some of the useful settings for figuresheets.
1. "Screen" tab
a. Scaling Factor: the default setting (100%) is for 17-inch monitors.
b. Autoredraw mode: When "Autoredraw"="True", the bitmap image of each figuresheet is stored in memory, which enables smooth redrawing of the figuresheet. Since it consumes much memory, you may select "False" (default), if your computer does not have enough memory.
2. "Printer" tab
Font Offset: this setting is primarily for HP LaserJet printers.
When printing with an HP LaserJet printer, you may notice a slight upward offset of printed texts relative to other drawings (for example, offset of Y axis labels relative to axis ticks in graphs), which may depend on the setting of printer options(for example, when "Download True Type fonts as outline soft fonts" is selected). In such a case try to set "Vertical" ="19" for "Font Offset".
3. "Objects" tab
Bitmap Pictures always on top: in this mode bitmaps are always drawn on top, irrespective to their Z order setting. You may check this option, if your printer driver does not support Z order for bitmaps and you want to keep WYSIWYG.
