# Python | Hist-Scatter Hybrid Plot

In this tutorial, we are going to learn how to hist-scatter plot using matplotlib in Python?

This is one of the most favored plots by data visualization experts. The scatter points and histograms are joined together and provide a complete picture of each data point. There are three different plots integrated into the complete figure. Following is an example of the implementation of a hist-scatter plot.

## Python code for hist-scatter hybrid plot

```import numpy as np
import matplotlib.pyplot as plt

x = np.random.randn(1230)
y = np.random.randn(1230)

def scatter_hist(x, y, ax, ax_histx, ax_histy):
ax_histx.tick_params(axis="x", labelbottom=False)
ax_histy.tick_params(axis="y", labelleft=False)

ax.scatter(x, y)

binwidth = 0.25
xymax = max(np.max(np.abs(x)), np.max(np.abs(y)))
lim = (int(xymax/binwidth) + 1) * binwidth

bins = np.arange(-lim, lim + binwidth, binwidth)
ax_histx.hist(x, bins=bins, color='black')
ax_histx.set_ylabel('Count')
ax_histy.set_xlabel('Count')
ax_histy.hist(y, bins=bins, orientation='horizontal', color='black')

# definitions for the axes
left, width = 0.1, 0.65
bottom, height = 0.1, 0.65
spacing = 0.005

rect_scatter = [left, bottom, width, height]
rect_histx = [left, bottom + height + spacing, width, 0.2]
rect_histy = [left + width + spacing, bottom, 0.2, height]

# start with a square Figure
fig = plt.figure(figsize=(8, 8))

ax = fig.add_axes(rect_scatter)
ax_histx = fig.add_axes(rect_histx, sharex=ax)
ax_histy = fig.add_axes(rect_histy, sharey=ax)

# use the previously defined function
scatter_hist(x, y, ax, ax_histx, ax_histy)

plt.show()
```

Output:

```Output is as Figure
```
