I am learning the breast cancer classification dataset in python. I am trying to plot histograms for each features, how am I able to arrange those histograms into three groups? Like the following screenshot:
What I am trying to achieve
Here is the code I used:
from sklearn.datasets import load_breast_cancer # sample data
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
data = load_breast_cancer()
# Turn the feature data into a dataframe
df = pd.DataFrame(data.data, columns = data.feature_names)
# Add the target columns, and fill it with the target data
df["target"] = data.target
# display(df.head())
mean radius mean texture mean perimeter mean area mean smoothness mean compactness mean concavity mean concave points mean symmetry mean fractal dimension radius error texture error perimeter error area error smoothness error compactness error concavity error concave points error symmetry error fractal dimension error worst radius worst texture worst perimeter worst area worst smoothness worst compactness worst concavity worst concave points worst symmetry worst fractal dimension target

# plotting
plotnumber = 1
fig = plt.figure(figsize=(20, 20))
for column in df.drop('target', axis=1):
if plotnumber <= 30:
plt.subplot(5, 6, plotnumber)
sns.distplot(df[df['target'] == 0][column], label = 'malignant')
sns.distplot(df[df['target'] == 1][column], label = 'benign')
plt.legend()
plt.title(column)
plotnumber = 1
fig.tight_layout()
What I have so far
I want to divide them into three groups: 'mean' group, 'error' group and 'worst' group. And each group includes 10 plots (5 row, 2 column)
