hydralien confirmed that the question is solved:
Well, speaking of use cases, I'm using Graphite of the "sort of" monitoring.
That means, I have different data values submitted now and then, when there's
some user activity, and not every second. So if showing that with
drawNullAsZero=1, graph would come in multiple spikes. That sort of works, but
the requirement is to show average values in between two spikes. Generally,
that's what best understood by customers. In general case it's pretty clear
when value changed because there's a line direction change there. However if,
for example, there's 4 equal values that cause a flat line (or values growing
so constantly that they form a single line) - well, that's a straight line of
values anyway.
So the conclusion is, it draws more readable graph in some cases. Would be nice
to have it in future versions either as a separate function or as an additional
parameter for keepLastValue(). However if not possible, I guess I can maintain
it separately just for myself.
Thanks for your answers.
