Dhistogram.rst1702 creates a variable named 'ts0' for a histogram entry with the key
1705 # echo 'hist:keys=next_pid:vals=$ts0:ts0=common_timestamp ... >> \
1708 The ts0 variable can be accessed by any subsequent event having the
1712 the '$' sign. Thus for example, the ts0 variable above would be
1713 referenced as '$ts0' in expressions.
