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.

Graph scaling and lin/log control

Here you can choose the scaling of the data
plots, the 3D scatterplots and the VRML files.
Log plots require data values greater than zero.

X Scale		Y Scale		Z Scale
Autoscale +/- 1% Autoscale +/- 2.5% Autoscale +/- 5% Autoscale +/- 10% Autoscale +/- 25% Autoscale +/- 50% Autoscale +/- 100% Autoscale +/- 150% Autoscale +/- 200% Manual Scale Max X: Min X:   Linear Scaling Logarithmic Scaling		Autoscale +/- 1% Autoscale +/- 2.5% Autoscale +/- 5% Autoscale +/- 10% Autoscale +/- 25% Autoscale +/- 50% Autoscale +/- 100% Autoscale +/- 150% Autoscale +/- 200% Manual Scale Max Y: Min Y:   Linear Scaling Logarithmic Scaling		Autoscale +/- 1% Autoscale +/- 2.5% Autoscale +/- 5% Autoscale +/- 10% Autoscale +/- 25% Autoscale +/- 50% Autoscale +/- 100% Autoscale +/- 150% Autoscale +/- 200% Manual Scale Max Z: Min Z:   Linear Scaling Logarithmic Scaling

Graph size

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

320 x 240 500 x 400 640 x 480 700 x 500 800 x 600 900 x 700 1024 x 768

Graph colors

Here you can select various color options for the output graphs.

Graph background color                                 Graph text color                                 Graph line color                                 Graph frame color                                 3D mesh color

Scientific Notation

Here you can control scientific notation on the data plots, the
3D surfaces, the contour plots, and the VRML model files.

Hold Coefficients Constant

Here you can enter values to hold coefficients constant during fitting.
Leave the entry field blank to let the coefficient fit normally.

z = B-Spline Interpolation Surface

3D rotation angles

Here you can select and rotate the 3D scatter and surface plots.
