Matplotlib Function To Create Histogram

```
import numpy as np
from matplotlib import pyplot as plt
# numpy array
data_array = np.array([1,1,1,1,1,2,3,3,3,4,4,5,5,6,7])
# plot histogram
plt.hist(data_array, range = (1,7), bins = 7)
```

In Python, the `pyplot.hist()`

function in the Matplotlib pyplot library can be used to plot a histogram. The function accepts a NumPy array, the range of the dataset, and the number of bins as input.
