Steps Set the figure size and adjust the padding between and around the subplots. As you see, there are no small ticks in between the larger numbered one. Dynamically find minor tick positions based on the positions of major ticks. This example illustrates the usage and effect of the most common locators. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. The matplotlib.ticker.LogLocator class is used to determine the tick locations for log axes. Matplotlib Server Side Programming Programming To set the log scale tick label number on the axes, we can take the following steps Set x and y axis limits (1 to 100), using ylim and xlim, on both the axes. Tick locators define the position of the ticks. Matplotlib loglog log scale minor ticks We can scale the minor ticks of the log scaled axis by specifying the list of the values to the value of the arguments subsx and subsy in the matplotlib.pyplot.loglog () function for the x-axis minor ticks and y This will open a UI which allows you to make any changes to your figure/axes.
