The matplotlib.ticker.LinearLocator is used to define the range and location of tickmarks of a plot when the user wants a exact number of ticks. LinearLocator thus differs from the default locator MaxNLocator, which does not necessarily return the exact user requested number of ticks.

The view range algorithm in matplotlib.ticker.LinearLocator has been changed so that more convenient tick location are chosen. The new algorithm returns a plot view range that is a multiple of the user requested number of ticks. This ensures tick marks to be located at whole integers more constistently. For example, when both y-axis of a``twinx`` plot use matplotlib.ticker.LinearLocator with the same number of ticks, the grids of both axis will be properly aligned at convenient tick locations.
