A Kaplan-Meier figure drawn the way Highcharts draws one: a stepped
line per arm, a linked scatter for the
censoring ticks, and a linked arearange for the confidence
band. Nothing in those series says the chart is a survival analysis, so
the curve says it itself — in the maidr block of Highcharts'
reserved custom subspace.
Click on the chart and use left and right arrow keys to walk the times,
and up and down to switch between the treated and control arms. The
description names the median survival; the rotor (r)
restricts navigation to the censored times, which the curve does not step
at and which nothing else in the announcement would distinguish.
