I know I can specify tick lengths using the
Ticks option in
Plot and related functions, and I also know about the CustomTicks package. But I stumbled over the symbols
Charting`$MajorTickLength (* 4 *)
Charting`$MinorTickLength (* 2.5 *)
and am curious if I could just set these to globally change tick sizes, without ever specifying the
Ticks option in plots. Changing these values, however, does not seem to have any effect. Does anyone know what these constants are there for?
