[Matplotlib-users] Problem with ganged candlestick plots

[Thomas B. <tho...@ya...>]

Hello,

When I run the following script, the ganged candlestick plots appear as
expected.  However, there is a second plot behind but sticking out (with
different x and y axes) that shouldn't be there.  Am I not doing this
correctly?  I can't see where in the code below I am mistakenly creating two
plots that overlap, or is there a bug with ganged candlesticks?

Tks vm,

Tom
