ncplot will plot netCDF files

Depending on the version you have, things might be a little different.

ncplot will allow you to select certain variables to plot, it will usually be against a set variable which is defined in the netCDF file.

To start ncplot:

  ncplot <filename>.nc

ncplot will then either open one or two windows, depending on the version. (If older version, one window will open with the different variables listed, if newer version, two windows will open, one is a graph and the other is where different variables are listed.).

Next, select the variable you want to plot versus the assigned variable that was defined in the netCDF file, usually time or distance.

There is basic modification allowed in ncplot, but if you need more specific modification, use a different program. This program also will not let you plot variables against each other easily.
