Text data editor
Cut-and-paste text or edit data here
Convert commas to spaces (1,2,0,3 yields 1 2 0 3)
Use comma as decimal separator (1,203 = 1.203)
Remove commas from text (1,2,0,3 yields 1203)
This data is provided as an example, cut and paste as needed to model your data. All lines of text that do not begin with a number are ignored. X Y 5.357 0.376 5.457 0.489 5.797 0.874 5.936 1.049 6.161 1.327 6.697 2.054 6.731 2.077 6.775 2.138 8.442 4.744 9.769 7.068 9.861 7.104
Spline Control Parameters
Here you can enter the control parameters for the spline.
Smoothness (larger numbers are smoother)
1: Linear
2: Quadratic
3: Cubic
4: Quartic
Spline order
Data labels for graphs
Here you can enter the X and Y data labels to be printed on the report graphs.
Label for first independent data (X)
Label for dependent data (Y)
Graph scaling and lin/log control
Here you can choose the scaling of the data plots.
Log plots require data values greater than zero.

Graph size
Here you can choose the size of the graphs. Smaller size files load quickly,
with less resolution while large files show more resolution but load more slowly.
