I am trying to plot some data, but I don't know how I can add the date values on the x-axis on my graph. Here is my code:

```
import pandas as pd
import numpy as np

%matplotlib inline
%pylab inline
import matplotlib.pyplot as plt
pylab.rcParams['figure.figsize'] = (15, 9)
df["msft"].plot(grid = True) 

```

![enter image description here](https://i.stack.imgur.com/65wKr.png)

The description of the image is a plot, but the x-axis just has numbers, but I am looking for dates to appear on x-axis. The dates are in the date column in the dataframe.

Here is what the dataframe looks like:

```
                  date  msft  nok  aapl  ibm  amzn
1  2018-01-01 09:00:00   112    1   143  130  1298
2  2018-01-01 10:00:00   109   10   185  137  1647
3  2018-01-01 11:00:00    98   11   146  105  1331
4  2018-01-01 12:00:00    83    3   214  131  1355

```

Can you offer some help on what I am missing?
