Data tab
The Data tab allows you to select the reading buffer that provides the data that is displayed on the
Graph tab. You can select up to four buffers. The data from each buffer is shown as a separate trace
on the Graph tab. You can also select the type of drawing style that is used on the graph.

Description
Displays the names of the reading buffers that are displayed on the
Graph tab. If no trace is selected, the active buffer is used.
You can select up to four reading buffers. The data from each
buffer is displayed as a separate trace on the graph.
If you select the active buffer, the trace is set to be the reading
buffer and the label "Active" is removed. The Graph tab will no
longer switch to the new buffer if you change the active buffer. To
return to plotting data from the active buffer, use Remove Trace to
remove all of the traces. When the active buffer setting is on,
"Active" is displayed before the name of the active buffer. When a
trace is using the active buffer and the active buffer changes, the
graph replots the data from the newly designated active buffer.
Selects a reading buffer that is used to supply the data for a trace
on the Graph tab. You can select up to four reading buffers and
specify the data type for the y-axis for each.
The colors for the traces are initially established in the order green,
blue, orange, and brown. Once a color has been assigned to a
trace, the color remains associated with that trace. For example,
trace 3 is assigned to orange. If trace 1 and 2 are removed, trace 3
becomes trace 1, but remains orange on the Graph tab. New
traces are assigned the next available color. In this example, if you
add a trace, it is set to green.
Removes the trace that is selected in the Trace Data list. This
removes the trace from display on the Graph tab.
If the active buffer is turned off ("Active" is not displayed before one
of the buffer names), removing all traces turns the active buffer
setting on.
Clears data from the selected buffer.
Sets the data to be plotted on the x-axis. You can select Scatter or
Time.
The drawing style determines how data is represented when there
are many data points. You can select Line, Marker, or Both.
When Line is selected, the data points are connected with solid
lines. When Marker is selected, the individual data points are
shown with no connecting lines. When Both is selected, the
individual data points are shown and the points are connected with
solid lines.
