This applet has two functions: plotting and finding the linear
function (of the form ) which best approximates the user
supplied data. Use it as follows:    1. Put the data to plot and
analyze in the Data section. Though the variables default to x
(the independent variable) and y (the dependent variable), they
can be renamed. Renaming them will cause the graph to be
updated. The values are entered one per line. The data can be
integers as well as real numbers. Scientific notation is allowed
(for ex. 2.1E3 for 2100 or 2.1E-3 for 0.0021). You can also copy
and paste data from any other application using the keys CTRL C
to copy and CTRL V to paste.   2. The buttons work as follows:
CLEAR will clear the data, the plot area and the RESULTS area.
PLOT will plot the data as points. ANALYZE will find the linear
function which best approximates the data, plot it and display
its equation in the RESULTS area.   3. The plot area (top,
right) will show the plo
