本文实例讲述了python绘图方法。分享给大家供大家参考。具体如下:

# -*- coding:utf-8 -*-
import matplotlib.pyplot as plt
def main():
  # 颜色列表
    colorList = ['b','g','r','c','m','y','k']
  # 共用的横坐标
    threadList = [1,2,4,8,10]
  # 设置横坐标和纵坐标的名称
    plt.xlabel('threads')
    plt.ylabel('concurrent')
     # 图的标题
    plt.title('concurrent test')
     # 要绘制的线的列表
    lines = []
    # 对应的线的名称
    titles = []
    # 第一根线的纵坐标
    dataList1 = [2,5,7,15,30]
    # 根据横坐标和纵坐标画第一根线
    line1 = plt.plot(threadList, dataList1)
    # 设置线的颜色宽度等
    plt.setp(line1, color=colorList[0], linewidth=2.0)
    # 线的名称
    titles.append('Linux')
    lines.append(line1)
     # 同理画第二根线
    dataList2 = [2,4,6,18,35]
    line2 = plt.plot(threadList, dataList2)
    plt.setp(line2, color=colorList[1], linewidth=2.0)
    titles.append('FreeBSD')
    lines.append(line2)
    plt.legend(lines, titles)
    plt.savefig('/home/workspace/test.png', dpi=120)
    #如果是pdf就,plt.savefig('/home/workspace/test.pdf')
if __name__ == '__main__':
  main()

希望本文所述对大家的Python程序设计有所帮助。
