In Python, with Matplotlib, how can a scatter plot with *empty* circles be plotted? The goal is to draw empty circles around *some* of the colored disks already plotted by `scatter()`

, so as to highlight them, ideally without having to redraw the colored circles.

I tried `facecolors=None`

, to no avail.

From the documentation for scatter:

```
Optional kwargs control the Collection properties; in particular:
edgecolors:
The string ‘none’ to plot faces with no outlines
facecolors:
The string ‘none’ to plot unfilled outlines
```

Try the following:

```
import matplotlib.pyplot as plt
import numpy as np
x = np.random.randn(60)
y = np.random.randn(60)
plt.scatter(x, y, s=80, facecolors='none', edgecolors='r')
plt.show()
```

**Note:** For other types of plots see this post on the use of `markeredgecolor`

and `markerfacecolor`

.

Would these work?

```
plt.scatter(np.random.randn(100), np.random.randn(100), facecolors='none')
```

or using plot()

```
plt.plot(np.random.randn(100), np.random.randn(100), 'o', mfc='none')
```
