Blurry Scatter Plot

Community matplotlib-users
1

For some reason when I plot a scatter plot like this:

plt.scatter(diamonds['carat'], diamonds['price'], color = 'black', alpha =
0.05)
plt.xlabel('Carat')
plt.ylabel('Price')

I get a blurry scatter plot as shown in the image

I want something more like this:

Any help would be greatly appreciated.

Thanks

Remove the alpha=0.05 kwargs which is setting the alpha to be almost transparent.

You may need to remove the alpha=0.05 or set it as 1 I think.
