我试图每50天保存收盘价(PX_LAST)的图像,增量为1天(例如,图1从0-50开始,图2从1-51开始,等等)。下面是我为整个数据集保存图像的代码
start_date = datetime. date(2001, 1, 3)
end_date = datetime. date(2020, 10, 16)
delta = datetime. timedelta(days=50)
while start_date <= end_date:
last_date = start_date
last_date+= delta
for i in range(148):
plt.plot(data.PX_LAST[start_date:last_date])
plt.savefig("spy_image" + str(i) +".png")
start_date += delta
