This example shows probably the most basic barplot you can do with python and matplotlib. The `bar()`

function used with the following parameters:

`x`

: The x coordinates of the bars. (x_pos in the example)`height`

: The height(s) of the bars.

```
# Libraries
import numpy as np
import matplotlib.pyplot as plt
# Create dataset
height = [3, 12, 5, 18, 45]
bars = ('A', 'B', 'C', 'D', 'E')
x_pos = np.arange(len(bars))
# Create bars
plt.bar(x_pos, height)
# Create names on the x-axis
plt.xticks(x_pos, bars)
# Show graphic
plt.show()
```
