Pareto chart

A pareto chart places the

 

data in descending

 

order and displays each

 

with its percentage of the

 

whole.

Setting up the plot (Plot Setup view)

The Plot Setup view (SP) enables you to specify many of the same plotting parameters as other apps (such as X Rng and Y Rng). There are two settings unique to the Statistics 1Var app:

Histogram width H Width enables you to specify the width of a histogram bin. This determines how many bins will fit in the display, as well as how the data is distributed (that is, how many data points each bin contains).

Histogram range H Rng enables you to specify the range of values for a set of histogram bins. The range runs from the left edge of the leftmost bin to the right edge of the rightmost bin.

Exploring the graph

The Plot view (P) has zooming and tracing options, as well as coordinate display. The Autoscale option is available from the View menu (V) as well as the menu.The View menu also enables you to view graphs in split-screen mode (as explained on page 91).

For all plot types, you can tap and drag to scroll the Plot view. You can also zoom in or out on the cursor by pressing +and wrespectively.
