python画图代码大全

以下是一些常见的 Python 画图库及其代码示例：

1. Matplotlib

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)

plt.plot(x, y)
plt.title('Sine wave')
plt.xlabel('X axis')
plt.ylabel('Y axis')
plt.show()

2. Seaborn

import seaborn as sns
import pandas as pd

df = pd.read_csv('data.csv')
sns.scatterplot(x='x', y='y', data=df)

3. Plotly

import plotly.graph_objs as go

x = [1, 2, 3, 4, 5]
y = [2, 4, 1, 3, 5]

fig = go.Figure(data=go.Scatter(x=x, y=y))
fig.show()

4. Bokeh

from bokeh.plotting import figure, output_file, show

x = [1, 2, 3, 4, 5]
y = [2, 4, 1, 3, 5]

output_file("line.html")

p = figure(title="Line plot", x_axis_label='X axis', y_axis_label='Y axis')
p.line(x, y, legend_label="Line", line_width=2)

show(p)

5. ggplot

from ggplot import *

df = pd.read_csv('data.csv')
ggplot(aes(x='x', y='y'), data=df) + geom_point()

以上是一些常见的 Python 画图库及其代码示例，你可以根据需要选择合适的库来绘制图形。
