您可以使用Matplotlib库来在python子区域中绘制多条折线的折线图。具体步骤如下:
1. 导入Matplotlib库
```python
import matplotlib.pyplot as plt
```
2. 创建一个Figure对象和一个Axes对象
```python
fig, ax = plt.subplots()
```
3. 在Axes对象中绘制多条折线图
```python
ax.plot(x1, y1)
ax.plot(x2, y2)
...
```
其中,x1、x2、...、xn和y1、y2、...、yn分别表示多条折线的横纵坐标数据。
4. 设置子区域的坐标范围
```python
ax.set_xlim(xmin, xmax)
ax.set_ylim(ymin, ymax)
```
其中,xmin、xmax、ymin、ymax分别表示子区域的横纵坐标范围。
完整代码示例:
```python
import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5]
y1 = [2, 4, 6, 8, 10]
y2 = [1, 3, 5, 7, 9]
fig, ax = plt.subplots()
ax.plot(x, y1)
ax.plot(x, y2)
ax.set_xlim(1, 5)
ax.set_ylim(1, 10)
plt.show()
```
运行代码后,会在屏幕上显示一个子区域绘制的多条折线的折线图。

python 绘制多条折线图
可以使用 Matplotlib 库来绘制多条折线图。以下是一个简单的示例代码:
```python
import matplotlib.pyplot as plt
# 数据
x = [1, 2, 3, 4, 5]
y1 = [1, 4, 9, 16, 25]
y2 = [1, 8, 27, 64, 125]
y3 = [1, 2, 4, 8, 16]
# 绘制折线图
plt.plot(x, y1, label='Line 1')
plt.plot(x, y2, label='Line 2')
plt.plot(x, y3, label='Line 3')
# 添加图例
plt.legend()
# 添加标题和标签
plt.title('Multiple Line Chart')
plt.xlabel('X Axis')
plt.ylabel('Y Axis')
# 显示图形
plt.show()
```
运行后会显示一个包含三条折线图的图形。可以根据需要修改数据和样式。
