• List
The initial default statistical data is List 1 for single-variable data, and List 1 and List 2 for
paired-variable data. You can specify which statistical data list you want to use for
x
-data and
y
-data.
• Frequency
Normally, each data item or data pair in the statistical data list is represented on a graph as
a point. When you are working with a large number of data items however, this can cause
problems because of the number of plot points on the graph. When this happens, you can
specify a frequency list that contains values indicating the number of instances (the frequency)
of the data items in the corresponding cells of the lists you are using for
x
-data and
y
-data.
Once you do this, only one point is plotted for the multiple data items, which makes the graph
easier to read.
• Mark Type
This setting lets you specify the shape of the plot points on the graph.
