To create a line chart in Python using plotly express with cumulative sum, you can follow these steps:
- Import the plotly express library:
import plotly.express as px - Load or create the data that you want to plot as a line chart:
data = [1, 2, 3, 4, 5] - Calculate the cumulative sum of the data using numpy:
import numpy as np data_cumsum = np.cumsum(data) - Create a dataframe with the original data and the cumulative sum data:
df = pd.DataFrame({ 'x': range(len(data)), 'y': data, 'cumulative_sum': data_cumsum }) - Plot the line chart using plotly express and the cumulative sum as the y-axis:
fig = px.line(df, x='x', y='cumulative_sum') fig.show() Here's the complete code:
import plotly.express as px import numpy as np import pandas as pd data = [1, 2, 3, 4, 5] data_cumsum = np.cumsum(data) df = pd.DataFrame({ 'x': range(len(data)), 'y': data, 'cumulative_sum': data_cumsum }) fig = px.line(df, x='x', y='cumulative_sum') fig.show() This will display a line chart with the cumulative sum of the data.
