histogram, based on the same data set, now looks like this:
A plot of frequency count, f
polygon.
A plot of the cumulative frequency vs. the upper boundaries is
known as a cumulative frequency ogive. You can produce scatterplots that
simulate these two plots by entering the proper data in columns 1 and 2 of a
new DAT matrix and changing the
window.

## Fitting data to a function y = f(x)

The program

be used to fit linear, logarithmic, exponential, and power functions to data sets
(x,y), stored in columns of the DAT matrix. In order for this program to be
effective, you need to have at least two columns in your DAT variable.
