Python中的非重复颜色和特定线宽

import matplotlib.pyplot as plt
import numpy as np

# 生成一些示例数据
x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x)

# 创建一个新的图形
plt.figure()

# 绘制第一条线，设置颜色和线宽
plt.plot(x, y1, color='blue', linewidth=2.0, label='Sine')

# 绘制第二条线，设置不同的颜色和线宽
plt.plot(x, y2, color='red', linewidth=3.0, label='Cosine')

# 添加图例
plt.legend()

# 显示图形
plt.show()

import matplotlib.cm as cm

# 使用颜色映射生成一系列颜色
colors = cm.viridis(np.linspace(0, 1, len(data_series)))

for i, series in enumerate(data_series):
    plt.plot(series['x'], series['y'], color=colors[i], linewidth=series['width'])

# 根据数据的重要性设置线宽
linewidths = [1.0, 2.0, 3.0]  # 示例线宽列表

for i, series in enumerate(data_series):
    plt.plot(series['x'], series['y'], color=series['color'], linewidth=linewidths[i])
