How to Format X-Axis Date Tick Labels for Clarity in Bar Graphs?

Formatting X-Axis Date Tick Labels

When creating bar graphs, the x-axis may display dates in a cluttered format, with repetitive elements such as the month and year. To optimize the display, users may wish to simplify the date formatting, focusing solely on the numerical dates.

To achieve this, matplotlib provides several date formatting options.

One method involves employing the matplotlib.dates module:

<code class="python">import matplotlib.dates as mdates</code>

Create a date formatter using the desired format string (in this case, '%d' represents the day):

<code class="python">myFmt = mdates.DateFormatter('%d')</code>

Finally, apply the formatter to the x-axis:

<code class="python">ax.xaxis.set_major_formatter(myFmt)</code>

This approach will remove the redundant month and year labels, leaving only the numerical dates on the x-axis.

For more advanced customization, refer to the matplotlib website for additional examples.
