Lucci-app-statistics graph scaling

Is there an option that when set in /etc/config/luci_statistics adjusts the scaling on graphs? I’d like to examine the standard deviation of the graph ‘ICMP Standard Deviation’ in the Ping tab.

Currently the line appears flat. I am able to calculate standard deviation by hand using the formula sqrt(sigma[x-xbar]^2/n-1) but if the option exists to scale the ICMP Standard Deviation graph so that the flat line exhibit some variation, I’ll take that!
