Bob, If you have Excel, you should be able to set up a curve from your
data sets. Enter and just let in plot away ( after you set up the initial
input/output in curves)

*Subject:* [pure-silver] D-LOG E CURVE DRAWING PROGRAM
*DEAR PURE SILVER,*
*Does anyone know of a curve drawing program that I can use to plot D-Log
E curves from the densities that I read off the test strips I create with my
step wedge? *
*To begin with I will use my densitometer. Later I may try it with my
scanner but, for now, please let me know about a program where you can set
the X axis at steps of .15 Log E units and the Y axis as Density and pump in
the readings from my densitometer. I am hoping that there is a program that
draws and smoothes the curve to fit the data.*
*Of course I would prefer a free download or to be told that it already
exists in my computer hidden in some Windows accessories program but I will
buy it if I must. *
*Thanks in advance. *
* CHEERS!*
