Attaching a data series to the secondary axis didn't enable
the secondary axis at the right side of the chart using the
sidebar (unlike in data series local menu -> Format Data
Series... -> Options).
Test: Click on the chart, select one of the data series, and
enable Data Series -> Align Series to Axis -> Secondary Y Axis.
