README VINNY DESKGRAPH v4.0


INTRODUCTION
Vinny DeskGraph is a very fast desktop FOUR 
data set XY graphing program. It can generate 
a series of 12 different graph types. It is 
easy to use and accepts and exports data 
through a variety of sources. Data can be 
entered manually into a spreadsheet. It can 
also be pasted into the spreadsheet from 
other applications such as Excel. Complete 
graphs can be loaded from VIN graph files. 
Vinny DeskGraph runs under Microsoft 
Windows 95/98/ME/NT/XP/Vista.Vinny DeskGraph 
provides for graph creation, display, editing, 
printing and savings in [.bmp] image format 
or [.vin] file formats. DeskGraph can perform 
8 different regression fits. 

INPUT
Data input is by:
     1-Cut, copy and paste from external 
       spread sheets.
     2-Key pad entry into a mini internal 
       spread sheet.
     3-Loading complete graph files with 
       [.vin] or [.gra] extensions.

OUTPUT 
Output is by:
     1-Cut, copy and paste to external 
       spread sheets.
     2-Copying value of the regression 
       coefficients.
     3-Copying Y interpolation values. 
     4-Saving complete graph files 
       with [.vin] extensions.
     5-Saving [.bmp] images 
     6-Printing graphs.

GRAPH SETTINGS
Graphs allow total freedom in setting up 
scales and grids. Directly input of values 
for Xmax, Xmin, Ymax and Ymin. Set X grids 
and Y grids form 1 to 20. Version 4.0 plots 
four data sets simultaneously. The 
following graph types are selectable 
for each data set: points, lines, bars,
lines & bars and  1st, 2nd, 3rd, 4th & 5th 
order polynomial, exponitial, log and power 
regression fits.
 
MATH AND REGRESSION
An interpolation window accepts X value inputs 
and provides an estimate for Y using a straight 
line connecting the XY points. It also provides 
Y estimates for each data set using the following: 
     1- 1st, 2nd, 3rd, 4th & 5th order polynomial fit.
     2- exponitial fit
     3- log regression fit.
     4- power regression fit.
The values for the regression coefficients along 
with the coefficient of determination are dislpayed 
and can be copied. A math constant "K" can be 
used to operate on data columns segments. Data can 
be copied and pasted to and from other applications 
in selected column segments or as a whole block.
