I want to plot a line chart with timestamp and values, but even thought my timestamp column in is datetime format, when I plot it, it won't show the date information like yyyy-mm-dd, but only the time.

The code I used to plot:

fig, ax = plt.subplots()
plt.plot('timestamp', 'values', data=df, marker='', markerfacecolor='blue', markersize=1, color='skyblue', linewidth=1)

The axis looks like below with no date information.

You didn't tell matplotlib which format you would like to have, so it uses the seamingly most useful one for intraday data. – ImportanceOfBeingErnest Sep 19 '19 at 18:57
@ImportanceOfBeingErnest, how do I let matplotlib know which format I want? – efsee Sep 19 '19 at 20:24
