Put any arithmetic expression using C/R/D/T (cumulative confirmed/recovered/death/tested), Cc (currently confirmed), dC/dR/dD/dT/dCc (newly confirmed/recovered/death/tested cases/currently confirmed derivation), ddC/ddR/ddD/ddT/ddCc (second derivation), P (population), or D_PAST (daily average total deaths 2010 – 2017) while %=10^2, k=10^3, M=10^6 and X starts from 0. Note that `tested` are available for Czechia only.
Ex: R/(C+R+D): Total recovered ratio. dR+dD: Newly closed cases. P/C: Every n-th person is confirmed. C/P: Nth part of the population is confirmed. C%/P: Nth-percent of the population is confirmed. CM/P: N people is confirmed in every million of citizens. ln(X), log(X, base=10), X^2: Guideline examples.
