The name of each variable that you add is appended to the label on the
axis. The default data point shape changes to help you distinguish data,
and a legend is displayed to identify the shapes.
6. Change, analyze, or explore the plotted data.
- Remove or change the variable on an axis by clicking the Add
Variable region again.
- View the plotted data in another supported plot type by selecting a tool
from the Plot Typesmenu.
- Choose the Graph Trace tool on the Analyze menu and press ◄or►
to move across the data points in the plot.
- The lists that you plot as variables can include incomplete or missing
cases. (A case is the data contained in a row of cells in the
Lists&Spreadsheet application.) The Lists&Spreadsheet application
displays a void as an underscore (“_”), and Data&Statistics plots no
data point for a void cell.
Manipulating Plotted Data
You can manipulate data points on the Data&Statistics work area to explore
their effects. For example, you could explore how a specific group of values
affects the median.
You can move a data point only in directions allowed by its definition. If a list is
defined with a formula in Lists&Spreadsheet, the points in Data&Statistics
may not move because of the formula’s restrictions. For example, you can
manipulate a plot that represents the result of y=x, but you can only move along
a line.
