Python: Plot a bar graph for a pandas data frame with x axis using a given column
<p>I want to plot a bar chart for the following pandas data frame on Jupyter Notebook. </p>

<pre><code>      | Month | number
-------------------------
    0 | Apr   |  6.5
    1 | May   |  7.3
    2 | Jun   |  3.9
    3 | Jul   |  5.1
    4 | Aug   |  4.1
</code></pre>

<p>I did:</p>

<pre><code>%matplotlib notebook
import matplotlib.pyplot as plt
import matplotlib
matplotlib.style.use('ggplot')
trend_df.plot(kind='bar')
</code></pre>

<p>How do I make sure x-axis is actually showing month here?</p>
