The charts

Each chart draws the rows of the table under it, in the table's order: sort a column to reorder the chart.Chart sets its axis.
Distribution: the range (line), mean ± SD (bar), median (tick) and mean (dot). Lengths of the regions are on a log scale.
Variation: the coefficient of variation, or the SD for the skews, which vary around zero.
Lifespan r: r with its 95% confidence interval (Fisher z). Lifespan map: r of every parameter in every region at once, bold where the Benjamini–Hochberg q-value over the map is below 0.05.

What the numbers are

Species: species with the region annotated. SD is the sample standard deviation, CV = SD / mean.
Base percentages are over A + C + G + T, so GC % + AT % = 100. Skews are on the L strand as deposited in RefSeq: GC skew = (G − C) / (G + C), AT skew = (A − T) / (A + T).
Min and Max name the species with the extreme value.

Lifespan columns

r is the Pearson correlation of the parameter with log₁₀ maximum lifespan within the group (5 or more species), and p its two-tailed p-value, as on the original MitoAge. They are not corrected for multiple testing or for shared ancestry: the plot shows Benjamini–Hochberg q-values and phylogenetic contrasts.

The original site labelled the base columns with their complements, so its skews have the opposite sign. Seemethods.
