I'm trying to increase the size of tick marks in my mathematica plots. I used the command
SetOptions[LinTicks, MajorTickLength -> {0.02, 0}, MinorTickLength -> {0.013, 0}];
which I found online. It seems to be no longer supported, but it changed my tick marks. I tried to restore the original settings using:
Apply[SetOptions[Plot, PlotStyle -> Automatic,
FrameTicksStyle -> Automatic, TicksStyle -> Automatic,
FrameTicks -> Automatic, Ticks -> Automatic]];
However it did not work. Any ideas gratefully received?
