unfortunately there is not (yet) a mechanism to do this.
it would be nice if you could specify (time_start, time_length) or
(time_start, time_end) or (time_length, time_end). and the plot generator
should be smart enough to know that any plot whose time parameters are not
a function of 'now' only needs to be generated once.
perhaps it could look something like this:
[ImageGenerator]
...
[[yesterday_images]] # like day_images, but for 24 hour period up to 24
hours ago
time_length = 86400
time_end = now - 86400
...
[[last_year_images]]
time_length = 31536000 # one year
time_start = 1451606400 # 1 january 2016
...
so time_start and time_end must be an epoch or a 'now' expression. a 'now'
expression is now plus or minus some offset, in seconds.
