The force-read feature consists on forcing periodic attribute reads for
those attributes being plotted with a :class:`TaurusTrendSet` object.
This allows to force plotting periodical updates even for attributes

Note that this is done at the widget level and therefore does not affect
the rate of arrival of events for other widgets connected to the same

The connection between the data items and this tool can be done manually

by discovering the compliant data items that share associated to the
