static const double LinearTick;

A constant equals to +1.5E+308 to represent that the ticks in a log scale axis should be 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 style increments.

For example, a log scale axis using LinearTick may have labels like 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, .....

This constant is used in Axis.setLogScale.
