From 6770aa96c984342c10485e347106f51ff60a136f Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sun, 14 Jan 2018 10:46:48 -0500 Subject: [PATCH] graphstats: Use alpha transparency when plotting the stats Use an alpha transparency on each of the stats, so that it is possible to see how the values overlap. Also, always enable the "awake time" stat - just use a lower alpha transparency for it. Also, explicitly set the graph size as some version of matplotlib have a different default.
