[Python] An easy way to visualize energy data interactively [plotly.express]
Overview
- Visualize energy data (electric energy) by python.
- Use a library called plotly in python instead of Excel.
Input data
- Only power data and time stamps are used this time.
Source code
#Library import
import pandas as pd
import plotly.express as px
#Reading sample data
data = pd.read_csv('./sample.csv',encoding='shift-jis',index_col=[0],parse_dates=[0])
#Data resampling (daily total)
data_month_sum = data.resample('D').sum()
#Line graph drawing
px.line(data_frame=data_month_sum,
x=data_month_sum.index,
y='Electric energy',
color_discrete_sequence=['yellow'])
Execution result
Summary
- You can create interactive graphs that cannot be done in Excel.
- If you know it, you can visualize it overwhelmingly quickly and get a bird's-eye view of the data.
