How order the "color legend"

Hello, is it possible to reorder the legend ? The current order is alphabetic but “values” are numbers, so I want an ascending order. In the dataframe, the column “values” have to be strings to use the color parameter, I can’t use integers.

The code : ggplot(data=df) + aes(x='algo', y='hv', color='values')

The figure :

Thank you

It is ‘exactly’ like factors and levels in R.

You can access the categorical attributes with df.column.cat. See https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Categorical.html

You have to turn your data into a pandas.Categorical

df2 = df.assign(values = pd.Categorical(df['values'], [optional ordered, unique list showing value order])

Don’t think you need to provide the optional list when dealing with integers.
