[gradsusr] How to calculate "quartile" like value usinggradsscript?

[Ryglicki, David CIV FNMOC]

And then I went ahead and attached my script, anyway.

Anyway, Brandon, the key trick I learned in the past for plume plots is a clunky work-around by defining the percentile variables in t and y, but setting x-size as t-size, which you'll see in my define statements. Later on, after a bubble sort, you can set defval, chunking through the time variable, and that'll eventually get you enough information to plot the percentiles as a faux x-variable.

It's extremely clunky and convoluted, but I got it to work to make plume plot percentiles.

Hi, Brandon.

Are you trying to make a plume plot or 2-D spatial plots?

I have known how to this.

Thanks.
