Pair that "partially-repeating vector source" with a new-style Throttle
block to keep the vectors trickle in more uniformly, by the way

There used to be the WX Strip chart which internally handled

One can achieve the same effect by using the vector sink and having a
Python block that produces the correct vector
on the appropriate schedule. Not as slick as have a "first class"
implementation, but I've been using that to produce
strip-charts for quite a while.

Hi Fabian,
I'm afraid we currently don't have that, no :(
Best I can offer is the "new" throttle block, which can, at lower
rates, make "blocks" of items appear in pieces smaller than a full
maximum buffer size (i.e., that solves the problem that if 10s of
samples fit in a buffer, GNU Radio will possibly only process a
block of items every 10s, which makes e.g. the Qt time sink
"stutter" very badly.)
Best,
Marcus!

Hi,
is there a way in GRC to get a rolling time sink?
That means no trigger, the signal just scrolls from right to left.
Best,
Fabian
