Plotting time in x axis using matplotlib












2















I have the following dataset:



pressuredfjan1[['Unit','Time1']].head()
Out[53]:
Unit Time1
0 321.3599 1970-01-01 00:00:40
1 321.3599 1970-01-01 00:04:40
2 321.6651 1970-01-01 00:06:40
3 320.7496 1970-01-01 00:10:40
4 322.2755 1970-01-01 00:14:40


I am trying to plot Unit against Time1 in an HH:MM:SS format.
I've tried the following code:



dates = dates.date2num(list(pressuredfjan1['Time1']))
fig = plt.figure(figsize=(20,10))
ax1 = fig.add_subplot(111)
ax1.plot(dates,pressuredfjan1['Unit'])
plt.show()


This gives me the plot, but I am not getting HH:MM:SS format in the x-axis. Instead, I'm getting 3.1, 3.2, 3.4...Le14 etc. Can somebody help me out here please? Thanks.

          You can use:



          import matplotlib as mpl

          pressuredfjan1['dates'] = pd.to_datetime(pressuredfjan1['Time1']).dt.strftime('%H:%M:%S')
          fig = plt.figure(figsize=(20,10))
          ax1 = fig.add_subplot(111)
          majorFormatter = mpl.dates.DateFormatter('%H:%M:%S')
          ax1.xaxis.set_major_formatter(majorFormatter)
          plt.plot_date(pressuredfjan1['dates'], pressuredfjan1['Unit'])
          plt.show()
