How to Eliminate White Space on the X-Axis in Matplotlib?

Eliminating White Space on X-Axis in Matplotlib

In matplotlib, when plotting data, there is often a margin added around the edges to ensure data fits within the chart. However, this can leave unwanted white space, particularly on the axes. To address this issue when dealing with white space on the x-axis, here are some effective options:

Adjusting Margins:

Use the plt.margins() or ax.margins() functions to specify the margins. For the x-axis, set the x argument to 0. This will remove any margin from the x-axis.

Example:

plt.margins(x=0)

Modifying Matplotlib Configuration:

To apply the change globally, modify the matplotlib rc file:

plt.rcParams['axes.xmargin'] = 0

Using plt.xlim() or ax.set_xlim():

Alternatively, you can manually set the limits of the axes using plt.xlim() or ax.set_xlim(). Determine the appropriate range and set the limits accordingly to eliminate white space.

Example:

ax.set_xlim(xmin, xmax)

Additional Considerations:

• The margins can also be adjusted for the y-axis using the y argument.
• To adapt these solutions to your specific code, adjust the figure object and axes references (fig, plt, and ax) as necessary.
• Refer to the matplotlib documentation for further information on margins and axis limits.
