im trying to plot the timeplot by matplotlib.pyplot.plot(df) . It gives a plot but with a long straight line connecting the discontinued datapoint (last data point on 2018-09-18T02:30:00.0 and the first data point on 2018-09-19T21:00:00.5). Is there a way to remove the connecting line between the data point gap?

Answer 1

sry... i think how i can do it... just use

df.plot(x=df.index.astype(str))

basically, convert my index from datetime to string, and use the strings as my x-axis
