The number of bars to be plotted determines the width of the bar. The H- and
V-VIEW are set to 10, by default. We changed the V-VIEW to better
accommodate the maximum value in column 1 of ΣDAT. Bar plots are useful
when plotting categorical (i.e., non-numerical) data.
Suppose that you want to plot the data in column 2 of the ΣDAT matrix:
•
Press „ô, simultaneously if in RPN mode, to access to the PLOT
SETUP window.

Scatter plots
We will use the same ΣDAT matrix to produce scatter plots. First, we will plot
the values of y vs. x, then those of y vs. z, as follows:
