Vinny Graphics Sample Math Problems:

Problem #1 Make an X,Y table from test data.

Given:
 Test data:
   X          Y
   4.79       98.312
   5.34       145.23
   6.93       201.67
   8.86       376.81

Create an X,Y  table with X going from 4 to 9 
in steps of 0.5. and round Y to 1 place.

Solution:
1- Open this text file in Vinny Graphics.
   (This is just a convenience. You could use any text editor)
2- Set Prefer Max Data to 30
   (Sets up length of new data files)
3- Open a new data set #1
   (The new data set should have 30 rows)
4- Drag mouse over above test data
   make sure to include both columns but
   do not include X Y titles.
   (Selects above data for the following copy)
5- Click Edit Copy.
   (Copies selected data to Windows clipboard)
6- Click on data set #1 cell [X1, 1]
   (Makes data set #1 active and selects cell [X1, 1])
7- Click Edit Paste.
   (Pastes data from Windows clipboard starting in selected cell) 
8- Right click data set #1 and select Y Fit.
   (Opens local pop up menu and then opens regression dialog)
9- Click 2nd Order Polynomial.
   (Does a 2nd Order Polynomial regression of the X,Y data in set #1)
10- Click OK.
    (Closes regression dialog and completes action)
11- Open a new data set #2.
    (The new data set should also have 30 rows)
12- Click Math index X and enter 11 for K.
    (This fills data set #2 X values with index number from 1 to 11.)
13- Click OK.
    (Closes math constant dialog and completes action)
14- Click Math Operate on X, X=X/K and enter 2 for K.
    (Divides all values in the X column of data set #1 by 2)
15- Click OK.
    (Closes math constant dialog and completes action)
16- Click Math Operate on X, X=X+K and enter 3.5 for K.
    (Adds 3.5 to all values in the X column of data set #1)
17- Click OK.
    (Closes math constant dialog and completes action)
18- Click on data set #2 cell [X2, 1] then Drag mouse
    over X2 column data from 4 to 9.
    (Selects X2 data for the following copy)
19- Click Edit Copy.
    (Copies selected data to Windows clipboard)
20- Click on data set #1 cell [X1, 5]
    (Selects data set #1 cell [X1, 5] for the following paste)
21- Click Edit Paste.
    (Pastes data from Windows clipboard into empty X cells and
    then automatically fills in a corresponding curve fit value for Y) 
22- Drag mouse over Y1 column data from 94.7... to 389.5...
    (Selects limited Y1 data the following math operation)
23- Click Math Operate on Selection S=Round(S) and
    enter 1 for K.
    (Rounds off selected Y data to one decimal place)
24- Click OK.
    (Closes math constant dialog and completes action)

The data table should look like this:

4	94.7
4.5	102.9
5	115.8
5.5	133.5
6	155.9
6.5	183
7	214.8
7.5	251.4
8	292.7
8.5	338.7
9	389.5
