plot_date

Use of plot_date has been discouraged since Matplotlib 3.5 and deprecated since 3.9. The plot_date function has now been removed.

• datetime-like data should directly be plotted using ~.Axes.plot.
• If you need to plot plain numeric data as :ref:`date-format` or need to set a timezone, call ax.xaxis.axis_date / ax.yaxis.axis_date before ~.Axes.plot. See .Axis.axis_date.
