I have a box-plot as below in python - matplotlib, could anybody help me to reduce years' spacing in x-axis (attached picture below)
fig, ax = plt.subplots(figsize = (16,8))
data = pd.concat([df_train.SalePrice, df_train.YearBuilt],axis=1)
sns.boxplot('YearBuilt','SalePrice',data=data)
plt.xticks(rotation=90)
plt.show()
Generate Some Sample Data:
import numpy as np
import pandas as pd
import seaborn as sns
from matplotlib import pyplot as plt
# Generate Some Sample Data
np.random.seed(15)
dr = np.repeat(pd.date_range('1872-01-01', '2011-01-01', freq='Y').year, 10)
data = pd.DataFrame({
'YearBuilt': dr,
'SalePrice': np.random.randint(0, 70_000, len(dr))
})
To set years at 5 year intervals get the unique
'YearBuilt' Columns and use np.where
to set ticks where year % 5
is 0:
fig, ax = plt.subplots(figsize=(16, 8))
sns.boxplot(x='YearBuilt', y='SalePrice', data=data, ax=ax)
years = np.sort(data['YearBuilt'].unique())
ax.set_xticklabels(np.where(years % 5 == 0, years, ''))
plt.xticks(rotation=90)
plt.show()
Alternatively set the tick locator
to a MultipleLocator
:
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker
import numpy as np
import pandas as pd
import seaborn as sns
# Generate Some Sample Data
np.random.seed(15)
dr = np.repeat(pd.date_range('1872-01-01', '2011-01-01', freq='Y').year, 10)
data = pd.DataFrame({
'YearBuilt': dr,
'SalePrice': np.random.randint(0, 70_000, len(dr))
})
fig, ax = plt.subplots(figsize=(16, 8))
sns.boxplot(x='YearBuilt', y='SalePrice', data=data, ax=ax)
ax.xaxis.set_major_locator(ticker.MultipleLocator(5))
ax.xaxis.set_minor_locator(ticker.MultipleLocator(1))
plt.xticks(rotation=90)
plt.show()
