Plot two columns based on values in another column

Question

I have a dataframe like follows:

df = pd.DataFrame({'year': [1,2,3],
                    'number' :[4,5,6],
                    'points': [10000,20000,30000]})

What is the easiest way to plot a figure that shows the relationship between number and points in each year? (ie, x-axis is "number" , y-axis is "points" and legend is "year")

Answer 1

I like using holoviews, you can use hvplot ( https://hvplot.holoviz.org/ ) for this:

import hvplot.pandas
df = pd.DataFrame({'year': [1,2,3],
                    'number' :[4,5,6],
                    'points': [10000,20000,30000]})
df.hvplot.scatter(x='number', y='points', color='year', clabel='year')

output:
