Pie chart
The pie chart displays each data point as a sector of a circle, where the sector’s area corresponds to the
percentage of the whole data set that the individual data point represents.
Setting up the plot
The Plot Setup view ( ) 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, as follows:
●
Histogram width—H Width enables you to specify the width of a histogram bin. This determines how
many bins will t 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 ( ) has zooming and tracing options, as well as coordinate display. The Autoscale option
is available from the View menu (
) as well as the menu. The View menu also enables you to
view graphs in split-screen mode.
For all plot types, you can tap and drag to scroll the Plot view. You can use a 2-nger pinch zoom performed
horizontally to zoom on the x-axis, vertically to zoom on the y-axis, or diagonally to zoom on both axes. You
can also zoom in or out on the cursor by pressing
or respectively.
