  WOW - DVTs - Color Mapper

Some browsers, such as Chrome, will no longer run applets that are embedded in a webpage.

An alternative is to download and open this file:
which will launch an updated version of the Color Mapper outside your browser.

You need a Java-enabled browser to run this applet.

As an alternative you can download and open the
Java Network Launching Protocol (JNLP) file linked above.

More info here.



You can select a different lake from the drop-down list of WOW study lakes.

The > and < buttons will advance/retreat to the next/previous profile in the database.

The >> and << buttons will automatically move through the data at the rate you set with the DELAY slider. You can skip over some profiles when you use these buttons by changing the drop down selection from "Show every profile" to some other value. For example, if the RUSS is scheduled to take 4 profiles every day, changing the selection to "Show every 4th profile" will cause the applet to move through the data more quickly by only displaying one profile for each day.

If you are at the beginning or end of the data, the affected directional buttons will be disabled.

More instructions:

Use the date slider to quickly select a particular date. If there is no data on the date you selected it will plot the first profile after that date.

(Note: After changing the lake or date, press the Get this Profile button to draw the new plot.)

Click on a different parameter choice to change the mapped and plotted parameters.

To see the actual data from the profile that is currently showing:

  • Press the Capture this Data button to write the data to the Captured Data Window.
  • Press the Show Captured Data button to view the window.
  • To copy this data to your own file:
    1. Select the data from the data window with your mouse and Copy it (Ctrl-C in Windows)
    2. Paste (Ctrl-V in Windows) it into a text file or spreadsheet.

Press the Copy this Plot button to send the current plot to a new window. This is handy if you want to compare plots from different lakes or dates. Here are some tips for saving or printing the plots.


Having Trouble?

The Color Mapper and Profile Plotter applets communicate with our server to send profiles to your computer, one profile at-a-time. This might be slow if a lot of people are using the applet at once, and it might not work at all if you are behind a firewall that blocks this kind of communication, or if you are using a browser that blocks embedded applets.

Try our new & improved Data Visualization Tools instead. You will get much better performance because the entire datasets are sent to your computer at the start, and no further communication with the server is needed.

Our Java Troubleshooting page might help if you are having any problems with Java.
