Easily set graphing range for a set of data points when doing regressions.
For TI-85


When doing regressions, I sometimes want to plot the points and draw a
regression line.  This program makes setting the range easier.  Enter two
lists: one for X values, another for Y values.  The program will set
xMin=min(xVar), xMax=max(xVar), xScl=(xMax-xMin)/10 and the same for the Y
values.  If you want a different number of tick marks on the axes, change
the denominator for xScl and yScl.  When the program finishes, it will
change the xVar and yVar lists to reals to save RAM.
