Step 3: Choose the parameter to map.

    Apply a -day running average.


Step 4: Choose starting and ending dates for the data in the color map.

Begin Date: --  
End Date: --

Step 5: Choose the axes for the color map.

Step 6: Choose the color scheme for the color map.

Specify a color to be used for missing data:
RGB colors here are specified with a hexadecimal code, where two characters
each specify the levels of red, green, and blue from 0 (hex 00) to 255 (hex FF).


Scale Type:  

Step 7: Make the color map, or reset the form and try again.

Construction of the color map may take a minute or two.
