12.2.2. Sample Data Time-Series Graphs
The two Sample Data Time-Series Graphs (middle and bottom of screen) let you view data
points over time for a user-selected variable over the range of samples contained in the selected
burst. Several variables are available, of which two can be displayed at the same time on each
graph - one on the left axis and one on the right axis of each graph. Use the
View|Select Mid/Bot
Graph Variable
(or its tool bar icon) to select the parameters to be displayed. The variables are ar-
ranged in "tabs" in the Select Time Series Variables dialog box, and include the following. Note:
Depending on your system’s configuration, not all tabs and/or variables may be available.
• Velocity (Velocity, Speed, Direction)
• Signal (Signal Amplitude, Mean Signal Amplitude, Correlation, Mean Correlation)
• Sensors (Temperature, Pressure, External Pressure)
• Compass (Heading, Pitch, Roll)
• Ext Sensors (External Sensor 1, External Sensor 2, External Sensor 3)
Notes:
(1) Moving the sample-data time-series marker (light blue pointer) will set the Sample Tabular
Data (§12.2.4) to the selected sample.
(2) Left-axis variables are displayed using a solid line; right-axis variables are displayed using a
dashed line. The axis scale can be changed by double-clicking on the appropriate axis scale.
(3) To magnify an area of the Sample Time-Series Graphs: (a) Select the Zoom-In icon from the
tool bar, (b) Click and drag your cursor from the desired starting point to the desired ending
point on either of the Sample Time-Series Graphs, (c) Release the cursor. You can now use
the horizontal scroll bar to view data to the left and right of the current position. To return the
graph to its full size, select the Zoom-Out icon from the tool bar.
(4) You can change the Sample Data Time-Series Graph to show burst data (i.e.; data on the top
graph can be shown on bottom graphs) by using
View|Show Samples/Bursts
or toolbar icon.
12.2.3. Burst Tabular Data
Information about each burst can be found in the Burst Information dialog box (upper right, but
movable). To move this dialog box, click and drag its "gripper" bar located at the top of the box.
Depending on the left-axis variable you have chosen for the Burst Data Time-Series Graph
(§12.2.1), the Burst Information dialog box can include the following tabular data. Note: De-
pending on your system’s configuration, not all listed variables may be available.
• Burst number - To quickly move to a specific burst number, double-click the burst number
and enter a new value.
• Burst Date - Date the selected burst began
• Burst Time - Time the selected burst began
• V1/X/E, V2/Y/N, V3/Z/U - Velocity components of selected burst in cm/s (if left-axis = Ve-
locity). The specific component depends on the selected velocity coordinate system.
• VelStD1, VelStD2, VelStD3 - Velocity standard deviation components of selected burst in
cm/s (if left-axis = Vel StD)
• Amp1, Amp2, Amp3 - Signal amplitude components of selected burst in counts (if left-axis =
Sig Amp)
• Amp StD1, Amp StD2, Amp StD3 - Signal amplitude standard deviation components of se-
lected burst in counts (if left-axis = Sig Amp StD)
