Python绘制图表的实用工具和辅助库介绍

import matplotlib.pyplot as plt

# x轴数据
x = [1, 2, 3, 4, 5]
# y轴数据
y = [1, 4, 9, 16, 25]

# 绘制折线图
plt.plot(x, y)

# 添加标题
plt.title("折线图示例")

# 添加x轴标签
plt.xlabel("x轴")

# 添加y轴标签
plt.ylabel("y轴")

# 显示图例
plt.legend(["折线"])

# 显示图表
plt.show()

import seaborn as sns
import matplotlib.pyplot as plt

# 加载示例数据
tips = sns.load_dataset("tips")

# 绘制散点图
sns.scatterplot(x="total_bill", y="tip", data=tips)

# 绘制线性回归线
sns.regplot(x="total_bill", y="tip", data=tips)

# 添加标题
plt.title("散点图示例")

# 显示图表
plt.show()

import plotly.graph_objects as go

# 创建2D柱状图数据
data_2D = [
    go.Bar(x=["A", "B", "C"], y=[1, 2, 3])
]

# 创建3D柱状图数据
data_3D = [
    go.Bar3d(x=["A", "A", "A", "B", "B", "B", "C", "C", "C"],
              y=[1, 2, 3, 1, 2, 3, 1, 2, 3],
              z=[1, 2, 3, 4, 5, 6, 7, 8, 9])
]

# 创建2D柱状图布局
layout_2D = go.Layout(title="2D柱状图示例")

# 创建3D柱状图布局
layout_3D = go.Layout(title="3D柱状图示例", scene=dict(zaxis=dict(title="Z轴")))

# 绘制2D柱状图
fig_2D = go.Figure(data=data_2D, layout=layout_2D)
fig_2D.show()

# 绘制3D柱状图
fig_3D = go.Figure(data=data_3D, layout=layout_3D)
fig_3D.show()
