Activating minor ticks in Matplotlib is as easy as calling the pyplot.minorticks_on () method. The scale must be linear with major ticks evenly spaced. show () Actual outcome. When setting a scatter plot's y axis to log-scale in matplotlib 2.0.0, it is data dependent as to whether y tick labels can be removed or not. Scales define the distribution of data values on an axis, e.g. Tick locators define the position of the ticks. The two relevant classes are Locator s and Formatter s. Locators determine where the ticks are, and formatters control the formatting of tick labels. @Mithril, df.plot() often displays the minor_locator, so you might want to try ax1.xaxis.set_minor_locator(plt.MaxNLocator(3)).Also remember to substitute the 3 for the number of ticks that you want to display.
