almost useful. needs
- logging serial data to a file OR
- graphing from a file and updating every xxx milliseconds.
tera term is a better option. it's slightly buggy when caching data and i haven't found a way to set a moving window to display results. and showing multiple graphs requires manual scaling, but still very useful. it's written in java so you'll need the JRE. i prefer this over having to install python like some of the other graphing programs do.
