- Section 1 - What is Datafit/Viewplot?
-
- Datafit is an an Engineering tool which is useful for generating
- functional equations and FFT calculations for tabular sampled
- data. It allows the user to import the data from a tab, comma, or space
- delimited file or enter it through a built in editor. For curve fitting,
- Cubic Splines and Least Squares techniques are used. The equation
- coefficients and calculated vs. entered data can be displayed and printed
- in tabular format. Statistics, such as correlation between entered and
- calculated data, are also calculated. Once equation coefficients are
- determined, the program can generate subroutine source code (Basic and C)
- which can readily be compiled and used to interpolate the data in user
- written programs. FFT calculations can be done on the entered data directly,
- or can be first spline fitted to allow a faster sampling rate. The FFT
- magnitude and phase calculations can also be displayed and printed in
- tabular format. In addition, output from this program for both the curve
- fitting functions and FFT calculations can be fed into Viewplot and the
- results can be viewed and compared graphically.
-
- Viewplot is an Engineering tool which is useful for plotting raw data, or
- functional equations and FFT calculations generated by the program Datafit.
- It can be used stand-alone, or launched from within Datafit once the programs
- have been registered. It has the ability to plot multiple curves from one
- or more datasets and display them in the same or separate windows
- simultaneously. Plots can be customized by formatting legends, numerical
- scaling, line colors, line styles and axis/title labels and fonts. The plots
- can be saved, printed or copied to the Windows clipboard for pasting into
- other applications.
-
- Section 2 - Machine Requirements
-
- Datafit/Viewplot version 2.2 is supported on Windows 3.1, Windows '95,
- and Windows NT version 3.51. The memory requirement is that you have
- enough to run Windows or Windows NT. If you are pushing your machine
- to the limit with just the operating system, make sure you have virtual
- memory (swap space) allocated. The programs now support all windows
- supported video resolutions.
-
- Section 3 - Distribution and License Information

-
- Section 4 - Automatic Installation using SETUP.EXE
-
- To automatically install Datafit/Viewplot for Windows on your hard drive:
-
- 1. If you have received the software from an archive in the form of a .ZIP
- file, copy the contents of the archive to a temporary directory and unzip
- the files. Copy the unzipped files to a floppy disk to keep as a backup.
- If you have received the software on a floppy disk directly from
- Engineered Software, the files will already be unzipped.
-
- 2. Place the disk in a floppy drive of your computer if you are installing
- from the floppy disk.
-
- 3. Open the File menu of the Windows program manager (if you are running
- Windows 3.1 or Windows NT) and select Run, or click on the "Start" button
- and select Run... (if you are running Windows '95).

- required.
-
- Section 5 - Version 2.2 and Previous Release Notes
-
- Datafit and Viewplot Version 2.2 is a FREE upgrade for current Version 2.1
- and previous users. Not every upgrade will be free, but interim releases
- will be. If there is a charge for upgrades in the future, it will be somewhat
- less than purchasing it for the first time. If you register the software,
- you will be notified of new releases. Work is going on on a daily basis,
- so register the software and submit your requests. We can't guarantee that
- we will honor every feature request, but we will do our best.

- Changes/Bug Fixes in Datafit and Viewplot Version 2.1
-
- 1. Text note box was added. This allows the user to type notes in the
- text box which are saved along with the projects. See the section
- "Entering Notes" in the online help.
-
- 2. FFT capabilities added. See the section "FFT Calculations" in the
- online help.
-
- 3. The calculated Y data for Cubic Splines was corrected in the View
- Equations/Statistics Panel. Previously the calculated data was
- displayed incorrectly because the solved coefficient data was
- not read in as double precision.
-
- 4. The installation program previously overwrote the datafit.ini
- and viewplot.ini files in the Windows directory if the software
- had already been installed. If the files already exist, they will
- no longer be overwritten.
-
- 5. Backward file compatility exists to previous versions.
-
- 6. If the default windows fonts Courier, Ms Sans Serif, or Arial
- were not present on the users system, the user would get an error
- which said "Invalid Property Value". A more descriptive error
- message comes up, and the program continues with the windows system
- standard font.
-
- 7. If the screen resolution is less than 800 x 600, a warning panel
- tells the user to change his screen resolution to a minimum of
- 800 x 600. The software will continue, but there will not be enough
- screen real estate to display the screens, hence buttons and text
- may not show up.
-
- 8. We now accept payment of various forms. See section 3 above.
-
- 9. Adding printing status panels.
-
- 10. The ability to display FFT calculations was added.
-
- 11. The default axis limits initialize to more 'reasonable' values
- instead of fitting to max and min values.
-
- 12. Input data is now displayed at the top of the equation list when
- opening or importing a new file.
-
- 13. Added 3D check boxes in colors and line style panels.
-
- 14. The ability to view plot coordinates by clicking was added. See
- the section "Show Coordinates" in the online help.
-
- 15. Backward file compatility exists to previous versions.
-
- 16. Adding printing status panels in Viewplot.
-
- Changes/Bug Fixes in Datafit and Viewplot Version 2.0:
-
- 1. Added additional Least Squares functions. These are common functions
- used in scientific and statistical analysis. See the section "Specifying
- Equation Types" in the online help.
-
- 2. Added ability to export source code in C and Basic to readily include
- the solved equations in other source code. See the section "Exporting
- Program Subroutines" in the online help.
-
- 3. Revised the View menu to more easily view the solution parameters. See
- the section "Viewing Output" in the online help.
-
- 4. You can now access Viewplot directly from Datafit. The software must
- be registered before this feature can be accessed. See the section
- "Viewing Output" in the online help.
-
- 5. Viewplot can run in either standalone mode as before, or can be accessed
- directly from Datafit. The software must be registered before this
- feature can be accessed. See the section "Viewing Output" in the Datafit
- online help.
-
- Stay tuned. Some more neat stuff is on the way....
