@fydel gonna figure out the axis precision for the diff charts at some point? should be a plugin propery? http://snowblossom.hamster.science/munin/hamsterpool/hamsterpool/snowblossom_diff.html

maybe try passing `--alt-y-grid` to rrdtool in the plugin

seems you can pass those via this http://guide.munin-monitoring.org/en/latest/reference/plugin.html#graph-args
