I feel ridiculous asking this, but is there a single function in Matlab that takes a series of integers/vectors (e.g. [2012,1,1,10,30,03]) or a Matlab time number (e.g. 735630) and converts it into a usable and plottable date of form 2012.01231 in one step? Thanks!

What do you mean by plotable ?
There are many functions related to dates
doc datenum
doc datevec
doc datestr

Maybe OP would want something like this (with modifications to make it generic):
2014+(datenum(d) - datenum('1-jan-2014'))/(datenum('1-jan-2015') - datenum('1-jan-2014'))

What about time between 0 and 1?
date1='01-01-2000'
date2='01-01-2001'
dat=datenum(date1,'dd-mm-yyyy'):datenum(date2,'dd-mm-yyyy')
out=mat2gray(dat)
