Matplotlib绘图时绘图

请参阅matplotlib绘图代码，但有时我遇到以下错误。

  if np.any(harmonics == 1) or np.any(harmonics == -1):
        for j in range (0,len(harmonics)):
            if harmonics[j] == 1 or harmonics[j]==-1:
                pats+=1
                sense = 'Bearish ' if harmonics[j]==-1 else 'Bullish '
                label = sense + labels[j] + ' found' 
                print(label)
                plt.title(label)
                plt.plot(np.arange(start,i+15),price.values[start:i+15])
                plt.scatter(current_idx,current_pat,c='r')
                filename = str(uuid.uuid1())[:8]
                print(filename)
                plt.savefig(filename)
                plt.close(filename)
                plt.show()

关于错误的跟踪，当我使用相同的代码巨大的数据输入时，它正在工作，但是如果我使用较少的数据，同样会失败
