Question

昨天和今天之间似乎出现了问题。我想知道你是否可以提供帮助？这都是使用iris运行Python的。

基本上当我昨天运行我的代码时，我在这里得到了第一张图，但今天我得到了第二张图：

如果我自己只运行一个CORDEX模型（蓝线）和一个观察到的数据（黑色），你可以看到它们都运行但是cordex模型似乎有一些有趣的时间。

所以我打印了每个时间坐标我得到以下CORDEX模型

我为观察到的数据得到了这个：

DimCoord([datetime.datetime(1901, 1, 16, 0, 0),

       datetime.datetime(1901, 3, 16, 0, 0), ...,

       datetime.datetime(2015, 12, 16, 0, 0)], standard_name='time', calendar=u'gregorian', long_name=u'time', var_name='time')

所以我有点困惑，为什么它昨天起作用但今天不起作用。你认为你可以帮忙吗？

谢谢！梨香

Answer 1

我不知道你的time坐标会发生什么，但解决方法可能是专门针对你的year坐标进行绘制：

qplt.plot(CCCma_mean.coord('year'), CCCma_mean, label='CanRCM4_ERAINT', lw=1.5, color='blue')
qplt.plot(CRU_mean.coord('year'), CRU_mean, label='Observed', lw=2, color='black')

Answer 2

谢谢@RuthC。这就是诀窍。它似乎是绘制时间作为默认值，因为一些数据是自1949年以来的天数，另一个是自1900年以来的天数，它在x轴上绘制了相隔49年的时间。虽然它前一天工作很奇怪！我的软件必须改变一些东西。

请注意，我还必须删除此代码：

Re-enter new password:
 ... Failed! Error: File './mysql/user.MYD' not found (Errcode: 13 - Permission denied)

否则x轴不会显示底部的年份数据。

欣赏它！梨香
