使用Python将数据曲线动起来

**基本思路：**

1.  首先绘制出几十张静态图片
2.  然后将静态图片合并为gif文件

*  首先运行 `StaticGraphs.py` 文件生成静态图片

import matplotlib.pyplot as plt
    from numpy import *
    from PIL import Image
    #------------------------------------------------------------
    xs = linspace(1, 50, 50)
    t = linspace(0, 50, 200)
    sint = sin(t)
    count=0
    for x in xs:
        plt.clf()
        plt.plot(t, sint, label='Sinusoidal Curve')
        plt.xlabel('Time (s)')
        plt.ylabel('Amplitude (V)')
        plt.grid(True)
        plt.axis([0, x, -1.5, 1.5])
        plt.savefig(r'.\temp\%d.jpg'%count)
        count = count+1

*  然后运行 `MovingGraph.py` 文件自动生成gif图片

from PIL import Image
    import os.path
    #------------------------------------------------------------
    def filedim2gif(giffile=r'.\temp\gif.gif', filedim=[], period=50, last=50):
        if len(filedim) ==0: return 0
    
        imageDim = []
        for f in filedim:
            imageDim.append(Image.open(os.path.join(r'.\temp', f)))
    
        duration = [period] * len(imageDim)
        duration[-1] = last
    
        imageDim[0].save(giffile,\
                         save_all=True,\
                         append_images=imageDim[1:],\
                         duration=duration,
                         loop=False)
    
        print('Save GIF: %s'%giffile)
        return 0
    
    count = eval(input('图片数量:'))
    filedimls = []
    for i in range(count):
        filedimls.append('{}.jpg'.format(i))
    filedim2gif(filedim=filedimls,period=count, last=count)
    input('任意键继续...')
