Number of Pages to Buffer spin box to control this setting.

The Buffer Options section allows you to turn the data buffering function
on or off. When the Buffer Data check box is checked, the option is active,
arrow buttons appear at the bottom of the graph, and the stopped graph can
scrolled backward in time for a specified interval into the past. You can
control the size of the buffer by specifying how many pages worth of data you
want to be available to scroll backward

The stopped graph has arrow buttons that appear below it to move backward
or forward one page at a time, moving to the earliest page or to the latest
(newest) page of the buffer. You can also manually navigate through the
buffered data using a right-button drag operation to move backward or forward
within the time frame of the captured buffer.

The Time Display section allows you to control how time is displayed below
the graph for the x-axis. You can show the date and time for each point, or just
the time. Alternately, you can suppress the time display completely.

The Numeric Data Display section controls whether or not the x-axis shows
milliseconds in its timestamp values. With the Data Precision setting, you can
control how many decimal places are shown numerically for the trace values in
the Selected Fields section of the main graph screen.
