GrADS Script Library

As of October 2019 I have begun updating the format and styling of this blog to be more modern and reflect more current standards. As such, the original "Tutorials" page has been updated. If you would rather use the page that was here previously, please follow this link.

Here is an ever growing library of GrADS scripts developed myself for GrADS-aholic. I figured it might be easier to just have a separate page with links to all the scripts readily available than to make you have to scroll through the scripts category on the main page and find them one at a time.

This is another one of those scrips that extends the flexibility of GrADS beyond it's intended purpose and might be useful for generating quick statistics on data sets that are in GrADS format without the intermediary step of saving data to a file to read into another program...

Boxplot takes data from a user input array in the form of a string with array elements separated by spaces (same as scatter.gs) and plots out a box plot using that data... Read More: Script Page | Download Here

Recently I have seen a few presentations that showed figures that had color bars made up of diamonds rather than rectangles (see below). I figured it might be fun to put together a quick script that allows you to do this in GrADS... Read More: Script Page | Download Here
