Multiple Curve Fitting

[deeps]

I am new to ZunZun...its truly a great service. My question is whether
we can fit multiple curves and output it in the same graph. Like for
example, if I am trying to do the Gauss 2D peak function and I have
four data sets that I want to fit to this function, Can I output all
the four curves in the same graph.

I am not sure whether ZunZun has the ability to do this. If not, are
there any alternate ways to solve this problem.

Thanks,
Deeps.

Thank you. Did you read the home page "About" section?

No, the site does not have this ability.

This can easily be done as discussed below using a modern spreadsheet
such as the free OpenOffice spreadsheet at http://www.openoffice.org/product/calc.html.

1) Fit each data set individually using http://zunzun.com or some
other fitting software.
2) Using the fitted coefficients, make many closely spaced synthetic
data points in the range of each data set.
3) Plot line graphs of the synthetic data points, one per data set
that was fitted, on a single graph.
