You also said:
This can be tested with a plot like this:
{{{
plot(x, (x,0,2), ticks=[[1,2],[1,2,3.5]],
tick_formatter=[["$x_1$","$x_2$"],["$y_1$","$y_2$","$y_3$"]])
}}}
There should probably be more checks like
{{{
len(ticks[0]) == len(tick_formatter[0])
}}}
and so on, but that can be addressed in a proper patch.
