To select the buffer that contains the data:
1. Press the MENU key.
2. Under the Views column, select Graph.
3. Select the Data tab. The Y-Axis table displays the buffers that are presently plotted on the Gra
ph
t
ab.
4. To add an additional buffer, select Add Trace and select the reading buffer to add. The Buffer
Element dialog box is displayed.
5. Select the buffer element to plot on the y-axis for the trace you are adding. Select Measure to
show measurement values on the y-axis, or select Source to show source values on the y-axis.
6. To remove a trace, select a buffer from the Y-Axis table and select Remove Trace.
7. Select the button next to Graph Type to specify the data to be plotted on the x-axis:
 Time: Plot the data values against time on the x-axis
 Scatter/IV: Plot data values against additional data values on the x-axis.
8. Set the Draw Style for the data. The drawing style determines how data is represented w
hen
t
here are many data points. You can select:
 Line: The data points are connected with solid lines.
 Marker: The individual data points are shown with no connecting lines.
 Both: The individual data points are shown and the points are connected with solid lines.
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 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.
Trace colors
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.
