Hi Luke,
As I wrote, when I ran your code (albeit directly reading in the two 
variables and dropping your timezone in "dates1") I got the axis label 
and tick labels. If it was some default setting, you shouldn't get them 
on _any_ plot. The following gives me a plot that looks okay.

temp1<-c(6.81,26.81,26.81,26.81,26.87,26.87,
26.87,26.87,27.06,27.06,27.06,27.06,
27.06,27.06,27.06,27.06,27.06,27.06,
27.06,27.06,27.06,27.06,27.06,27.06,
27.06,27.06,27.06,27.06,27.06,27.06,
27.06,27.06,27.06,27.06,27.06,27.06,
27.06,27.06,27.06,27.06,27.06,27.00,
27.00,27.06,27.06,27.06,27.00,27.00,
27.06,27.00,27.00,27.00,27.00,27.00,
27.00,27.00,27.00,26.94,26.94,26.94,
26.94,27.00,26.94,26.94,26.94,26.94,
26.94,26.94,26.94,26.94,26.94,27.00,
26.94,26.94,26.94,26.94,26.94,26.94,
26.94,26.94,26.94)
