Section 8
Reporting and Plotting Data with EcoWatch DCP
8.1 Introduction
There are many features in EcoWatch DCP related to viewing, plotting, manipulating and
reporting data collected from the 6200 DCP. In this section we describe some of the most
common functions you will use. As with the 6200 DCP menu described in the previous section,
a convenient Windows Help section and tutorial is available to guide you through the
examination of your data. We recommend that you use these help features for a comprehensive
understanding of EcoWatch DCP.
For the purposes of describing and demonstrating EcoWatch DCP plotting, reporting and data
manipulation capabilities, we use the file SAMPLE.DAT, located in you data folder. This file
will be copied to your hard drive during EcoWatch DCP installation and should be available for
you to follow the instructions below.
When you are ready to move beyond the SAMPLE.DAT example and analyze data collected
from the 6200 DCP, locate and open the appropriate .DAT file. These data files are located by
default in c:\ecowwin\data\. An example filename is 1097CM01.DAT. This filename contains
important information that was described in Section 7.4. Do not change the filename of the
6200-created .DAT file until you are completely finished using the .S62 configuration file that is
associated with this set of data.
NOTE: In the instructions below that refer to clicking the mouse button, we always refer
to the left mouse button unless otherwise specified.
8.2 Opening a Data File
If EcoWatch DCP is not running, double click on the EcoWatch DCP icon. Click on File to
view a drop-down menu similar to the one shown in Figure 8.1 below. From this menu click on
Open, then locate the drive and directory where SAMPLE.DAT (or your file of interest) resides.
Alternatively, if you have been using EcoWatch DCP during setup and checkout, you may be
able to click on the file of your choice in the most recently opened files.
Once the SAMPLE.DAT file is open you should see a plot (Figure 8.1) which graphically
represents 7 days of sonde data for 6 different water quality parameters plotted as a function of
date and time. Each set of data is autoscaled to allow you to see the minimum and maximum
values for each parameter during the one-week study.
