[PD] running plot of sampled data

Hi,

I am trying to continuously plot a sequence of data (from snapshot~), in 
order to get a running visualization of sound levels. Sampling should 
occur every 10..100ms and I want to see about 1000 past data points.

My first guess was to use an array of that size and to write data to it 
via tabwrite, indexed by modulo_counter. Unfortunately, the frequency at 
which the plot of the array is updated, is way too low (every one second 
or so). Is there a a way of changing that frequency? If not, are there 
better alternatives?

Thanks for your help, Matthias
