"palette as line color" gnuplot functionality

Is there any way to use the "palette as line color" functionality built into gnuplot with this crate? I need to change the color of a line based off of a third "z" dimension, and looking through your documentation it's unclear if that type of graph is supported.

Essentially, I am trying to follow this guide: [http://www.gnuplotting.org/using-a-palette-as-line-color/](url)

Thanks!
