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

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!

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