8. How to use the Data Visualizer Application
The Data Visualizer application provides a graphical interface for a user to view data
stored by the Data Server. For example, sensor data collected by a particular glider,
transferred to Dock Server, and stored on a Data Server can be viewed along different
axis, superimposed on other data, and zoomedin on, all using a remote Data
Visualizer application. Data Visualizer can run on any machine that is networked to a
Data Server machine and has Java JRE 1.4.2 or later, and Java Web Start (typically
part of the JRE) installed.
8.1 Installing Data Visualizer
For a first time install of Data Visualizer, follow steps similar to those for installing Glider
Terminal (Section 3.1) and Glmpc Terminal (Section 6.1), the only difference being to
click on the link labeled “Click here to install and run Data Visualizer” .
8.2 Starting Data Visualizer
To launch Data Visualizer after an initial install, follow the steps in this section.
1.
Double click the desktop icon labeled “Data Visualizer” or select the item labeled
“Data Visualizer” from the “All Programs” menu (Windows XP). The Data
Visualizer window should appear (Figure 81).
NOTE: Each time Data Visualizer is launched, the machine of the initial Data
Visualizer install is checked for a new version of Data Visualizer. If a new version
is found, it is installed and launched.
A new version of Data Visualizer is placed on the Dock Server machine each time
the Data Server application is upgraded.
When launched for the first time, Data Visualizer attempts to connect to the machine
from which it was Web Started. For example, Figure 81 shows a Data Visualizer
connected to dockserver64.webbresearch.com. When further launched, Data Visualizer
attempts to connect to the machine last selected for connection.
