Dataset
Since scatter plot is a type of chart that displays values for two numerical variables for a set of data, we will load the iris
dataset:
url = 'https://raw.githubusercontent.com/holtzy/The-Python-Graph-Gallery/master/static/data/iris.csv'
df = pd.read_csv(url)
Default theme
The plotnine
default theme is the same as the ggplot2
default theme in R:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point()
)
White background theme
There are various theme with white background in plotnine
.
Here is an example of the theme_minimal()
theme:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point() +
theme_minimal()
)
Dark background theme
If you're looking for a dark background theme, you can use the theme_dark()
theme:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point() +
theme_dark()
)
Empty theme
If you want to remove all the elements of the theme, you can use the theme_void()
theme:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point() +
theme_void()
)
Themes with grid
If you want to add a grid to your plot, you can use the theme_classic()
theme:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point() +
theme_classic()
)
Theme with full grid
If you want to add a full grid to your plot, you can use the theme_bw()
theme:
(
ggplot(df, aes(x='sepal_length', y='sepal_width')) +
geom_point() +
theme_bw()
)
