Plot temperature and current graphs
- Have units - Samples are limited - pglive is used for better live graphs -- Also fixes bug with constantly updating normal pyqtgraphs where it will bug out if right-clicked on and context menu is brought up --Since pglive requires pyqtgraph == 0.13.3, upgrade pyqtgraph to that too.
