Add labels to matplotlib
ax=final.plot(x='Date',figsize=(16,8))
def label_point(x, y, val, ax):
a = pd.concat({'x': x, 'y': y, 'val': val}, axis=1)
for i, point in a.iterrows():
ax.text(point['x'], point['y'], str(point['val']))
label_point(final['Date'], final['Actual Calls'].fillna(0), final['Actual Calls'].fillna(0).astype(int), ax)
label_point(final['Date'], final['Predictions'].fillna(0), final['Predictions'].fillna(0).astype(int), ax)
Run Jupyter Notebook from other notebook
from IPython import get_ipython
from tqdm.notebook import tqdm
ipython = get_ipython()
for col in tqdm(['Calls - BC/PIC1 - Active','Calls - BC/PIC1 - Pre/Post','Calls - Death','Calls - PAY','Calls - PIC2']):
ipython.magic("run Modelling.ipynb")
Add Colored boxes to Jupyter notebook
#Red box
<div class="alert alert-block alert-danger">

Annotate a plt plot
fig=fin.groupby(['F-18'])['Tweet'].count().plot(kind='bar')
## For vertical Bar plots add -
for p in fig.axes.patches:
p.axes.annotate(format(p.get_height(), '.0f'), (p.get_x() + p.get_width() / 2., p.get_height()),ha = 'center', va = 'center', xytext = (0, 10), textcoords = 'offset points')
## For horizontal Bar plots add -
for p in fig.axes.patches:
p.axes.annotate(format(p.get_width(), '.0f'), (p.get_width() , p.get_y() + p.get_height() / 2.),ha = 'center', va = 'center', xytext = (10, 0), textcoords = 'offset points')
Add Snippets to the Jupyter Notebook
jupyter --config-dir
config_dir=" " # updated from previous output
import requests
with open(r'{}\custom\custom.js'.format(config_dir),'wb') as t:
t.write(requests.get("https://raw.githubusercontent.com/bharatb964/packages/master/custom.js").content)
