concept tic mark in category gnuplot

This is an excerpt from Manning's book Gnuplot in Action.
Gnuplot handles most everything else by itself: it sizes the graph and selects the most interesting plot range, it draws the border, and it draws the tic marks and their labels. All these details can be customized, but gnuplot typically does a good job at anticipating what the user wants.
Subdivision markers or tic marks are placed on the axes of a plot to indicate the scale of the graph. Only if tic marks are present can a viewer infer quantitative information from a graph. Suitably chosen tic marks are therefore of critical importance to any well-constructed graph. Fortunately, gnuplot handles tic marks well on its own, and you rarely need to customize tic-mark generation and labeling. But for the few cases when you do have special requests, here’s how to do it.
