绘制分段数据，x轴限制

import matplotlib.pyplot as plt
import numpy as np

# 示例数据
x = np.linspace(0, 10, 100)
y = np.sin(x)

# 创建分段
bins = [0, 3, 6, 9, 10]  # 自定义分段点
x_segments = []
y_segments = []

for i in range(len(bins) - 1):
    mask = (x >= bins[i]) & (x < bins[i+1])
    x_segments.append(x[mask])
    y_segments.append(y[mask])

# 绘制分段数据
plt.figure(figsize=(10, 6))
for x_seg, y_seg in zip(x_segments, y_segments):
    plt.plot(x_seg, y_seg, label=f'Segment {bins.index(x_seg[0])}-{bins.index(x_seg[-1])+1}')

# 设置x轴限制
plt.xlim(2, 8)  # 例如，只显示x轴从2到8的部分

plt.xlabel('X Axis')
plt.ylabel('Y Axis')
plt.title('Segmented Data with X-axis Limits')
plt.legend()
plt.grid(True)
plt.show()
