+# Peroxide Plot Feature 2
+
+## Prerequisites
+
+* Python - `matplotlib`, `scienceplots`
+
+## Description
+
+This code extends Plot Feature to generate all supported style outputs with a single call.
+
+## Process
+
+Just run!
+
+```sh
+cargo run --release
+```
+
+## Result
+
+***Due to issues (probably with PlotStyle.style.use) with specific context settings the Nature style generation is currently disabled in `main.rs`.***
+
+- Default style
+ ![plot](plot.png)
+
+- Science style (Default style for scienceplots)
+ ![plot](plot_science.png)
+
+- Nature style
+ ![plot](plot_nature.png)
+
+- IEEE style
+ ![plot](plot_ieee.png)
