Subject: statistics: memory plugin - improve graph by better scaling of y-axis
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9a06498dbdf5f5878d2ce86a4b9ac8abc9173bdc;p=project%2Fluci.git

statistics: memory plugin - improve graph by better scaling of y-axis

Utilise alt_autoscale_max to make the memory chart y-axis to scale better
for devices with e.g. 128 MB RAM.

Also fix the axis min value to 0.
