Axis Position

The position parameter in scale_x_(), scale_y_() functions controls position of the axis:

• ‘left’, ‘right’ or ‘both’ for y-axis;

• ‘top’, ‘bottom’ or ‘both’ for x-axis.

import pandas as pd

from lets_plot import *

LetsPlot.setup_html()
LetsPlot.set_theme(theme_grey())

df = pd.read_csv('https://raw.githubusercontent.com/JetBrains/lets-plot-docs/master/data/iris.csv')
df.head(3)

	sepal_length	sepal_width	petal_length	petal_width	species
0	5.1	3.5	1.4	0.2	setosa
1	4.9	3.0	1.4	0.2	setosa
2	4.7	3.2	1.3	0.2	setosa

1. Default Axis Position

p = (ggplot(df) + geom_point(aes("sepal_width", "sepal_length", color="species"), size=5)
      + scale_color_brewer(palette="Set1")
    )
p

2. position="right"

p + scale_y_continuous("Sepal Length", position="right")

3. position="top"

p + scale_x_continuous(position="top")

4. position="both"

(p
 + scale_x_continuous("Sepal Width", position="both")
 + scale_y_continuous("Sepal Length", position="both")
)

4.1 Lets use equal units on the X-axis and on the Y-axis.

(p
 + scale_x_continuous("Sepal Width", position="both")
 + scale_y_continuous("Sepal Length", position="both")
 + coord_fixed()
)
