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 plot.

• If you need to plot plain numeric data as Matplotlib date format or need to set a timezone, call ax.xaxis.axis_date / ax.yaxis.axis_date before plot. See Axis.axis_date.
