[rrd-users] rrd graph start/end times with DEF start/end times

I am upgrading to the 2.28 (from a very old version) and I see that
the DEF statement not has start and end time specifications.
I would like to use this to generate multiple MAXIMUM over different time periods
using PRINT and one call to rrd graph.
I save a statistic in several differend RRAs in one RRDFILE.
I want the MAXIMUM value over the last 3 hours, the last 24 hours etc.
It looks like I could, in the def commands specify something like
Then use the following VDEFS
Then the PRINT statements
PRINT:stat3hoursMax:"3 hour MAX: %8.4lf"
PRINT:stat24hoursMax:"24 hour MAX: %8.4lf"
My questions are
0. Can I request different start/end times for the same DS in multiple DEF statements in one command?
1. If so, do I need to specify a start and end time for the as an argument to the graph command?
