[英]Arrange boxplots as a grid with seaborn `FacetGrid`
I have a data frame with three columns Features, CV-fold, Accuracy, Network
.我有一个包含三列Features, CV-fold, Accuracy, Network
的数据框。 I want to have a boxplot for each Network, grouped by the Features and the CV-fold for the axis (see example image).我想为每个网络绘制一个箱线图,按轴的特征和 CV 折叠进行分组(参见示例图像)。
df = pd.read_csv(path)
df['Features'] = df["Features"].astype('category')
ordered_features = sorted(df.Network.value_counts().index)
df = df.loc[df['Accuracy'] > 0.1]
df.Accuracy = df.Accuracy*100
#sns.color_palette("husl", len(df['CV-fold'].value_counts().index))
#sns.set_palette('husl', len(df['CV-fold'].value_counts().index))
g = sns.FacetGrid(df, row="Network", row_order=ordered_features,
height=3, aspect=3, legend_out=True, despine=False)
g.map(sns.boxplot, x="CV-fold", y="Accuracy", hue="Features", data=df, palette='muted').add_legend()
g.set_axis_labels("", "Accuracy (%)")
Because I have 8 different networks, I would like to not have them all in a column or a row, but formatted in a grid (eg 2x4).因为我有 8 个不同的网络,所以我不想将它们全部放在一列或一行中,而是在网格中格式化(例如 2x4)。 Additionally, even though sharex
is not enabled, the x-axis is only labeled at the very bottom graph.此外,即使未启用sharex
,x 轴也仅标记在最底部的图形中。
How can I do that?我怎样才能做到这一点?
You would use the col_wrap
keyword argument to get your plots on multiple rows with multiple columns.您可以使用col_wrap
关键字参数在多行多列上绘制图。
For repeating the x-axis labels use ax.tick_params()
.要重复 x 轴标签,请使用ax.tick_params()
。
Example:例子:
import seaborn as sns, matplotlib.pyplot as plt
tips = sns.load_dataset('tips')
ordered_days = sorted(tips['day'].unique())
g = sns.FacetGrid(tips,col='day',col_order=ordered_days,col_wrap=2)
# change this to 4 ^
g.map(sns.boxplot,'sex','total_bill',palette='muted')
for ax in g.axes.flatten():
ax.tick_params(labelbottom=True)
plt.tight_layout()
plt.show()
