Simple Question from a New User

Hi All-

I am pretty familiar with Generic Mapping Tools, but there is some things that I am struggling with in global mapper, I am sure it's simple- so if anyone can point me in the right direction, that would be great.

I am trying to import a txt file with lat, long, and 3rd column with a value between 0 and 1. I want to have the dots from the file be a certain color based on the 3rd column (i.e. 0.0 to 0.12 is light blue, 0.121 to 0.25 dark blue...)

Like I said, I am sure it's a breeze but I haven't figured out how it works.

Thanks so much!

    For future reference a better subject line could help more: "Importing TXT File - Issue";

    OK, I''l bite.

    Go to "open" and select the "generic ascii text file" dialogue
    Select the "point only" option (top left) and in the lower right un-tick the "treat 3rd coordinate value as elevation" and tick the "include attributes from lines with coordinate data"
    There are other options you can play with.
    Click OK and when loaded go to the overlay control centre. Click on the new layer and then on the options button.
    Go to the point styles tab select the "apply styling based on attribute/name values". The rest should be self explanatory.

    I hope this helps.
