From 6c4355cd13ae47c327ddc5e9b66623e44ba5b118 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sat, 1 May 2021 12:25:55 +0100 Subject: pybootchart/draw: Avoid divide by zero error When disk stats don't run frequenctly enough, we see divide by zero errors. The code already has a fallback path so ensure we use it for this case too.
