How to create a stacked bar chart for my DataFrame using seaborn [duplicate]
I have a DataFrame df
:
df = pd.DataFrame(columns=["App","Feature1", "Feature2","Feature3", "Feature4","Feature5", "Feature6","Feature7","Feature8"], data=[['SHA', 0, 0, 1, 1, 1, 0, 1, 0], ['LHA', 1, 0, 1, 1, 0, 1, 1, 0], ['DRA', 0, 0, 0, 0, 0, 0, 1, 0], ['FRA', 1, 0, 1, 1, 1, 0, 1, 1], ['BRU', 0, 0, 1, 0, 1, 0, 0, 0], ['PAR', 0, 1, 1, 1, 1, 0, 1, 0], ['AER', 0, 0, 1, 1, 0, 1, 1, 0], ['SHE', 0, 0, 0, 1, 0, 0, 1, 0]])
# display(df)
App Feature1 Feature2 Feature3 Feature4 Feature5 Feature6 Feature7 Feature8
0 SHA 0 0 1 1 1 0 1 0
1 LHA 1 0 1 1 0 1 1 0
2 DRA 0 0 0 0 0 0 1 0
3 FRA 1 0 1 1 1 0 1 1
4 BRU 0 0 1 0 1 0 0 0
5 PAR 0 1 1 1 1 0 1 0
6 AER 0 0 1 1 0 1 1 0
7 SHE 0 0 0 1 0 0 1 0
I want to create a stacked bar chart so that each stack would correspond to App
while the Y axis would contain the count of 1
values and the X axis would be Feature
.
It should be similar to this bar chart with the only difference that now I want to see stack bars and a legend with colors:
df_c = df.iloc[:, 1:].eq(1).sum().rename_axis('Feature').reset_index(name='Count')
df_c = df_c.sort_values('Count')
plt.figure(figsize=(12,8))
ax = sns.barplot(x="Feature", y='Count', data=df_c, palette=sns.color_palette("GnBu", 10))
plt.xticks(rotation='vertical')
ax.grid(b=True, which='major', color='#d3d3d3', linewidth=1.0)
ax.grid(b=True, which='minor', color='#d3d3d3', linewidth=0.5)
plt.show()
You could use pandas plot as @Bharath suggest:
import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)
Output:
Updated:
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Updated Pandas 0.21.0+ reindex_axis
is deprecated, use reindex
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Output:
