将Python中的多个图形合并到一个图形中

Question

嗨我试图将4个图组合在一起，并且我不确定它是如何完成的，4个图是plotMultiDays（MergedDataJuly）到plotMultiDays（MergedDataDec）

任何帮助都会很棒。 下面是代码：

MergedDataJuly=MergedData[MergedData.expiration == Date(2016,7,16)]
MergedDataAugust=MergedData[MergedData.expiration == Date(2016,8,20)]
MergedDataSep=MergedData[MergedData.expiration == Date(2016,9,17)]
MergedDataDec=MergedData[MergedData.expiration == Date(2016,12,17)]




plotMultiDays(MergedDataJuly,AgainstMarket='Yes')
plotMultiDays(MergedDataAugust,AgainstMarket='Yes')
plotMultiDays(MergedDataSep,AgainstMarket='Yes')
plotMultiDays(MergedDataDec,AgainstMarket='Yes')

plotMultiDays(MergedDataJuly)
plotMultiDays(MergedDataAugust)
plotMultiDays(MergedDataSep)
plotMultiDays(MergedDataDec)
