Re: How to resample continuosly time data to be represented real time ?

Actually I once accidently programmed something, which somebody else 
described as a low pass filter, instead of a moving average.

It works like this:

Suppose you are limited to 5 values.

V1 V2 V3 V4 V5

Now value 6 comes in, what you do is this:

V1  V2   V3   V4   V5  V6
  +    +    +    +   +
  /2   /2    /2  /2  /2
  NV1  NV2  NV3   NV4  NV5

Here is the source code version in case the drawing above doesn't come 
through:

V1 to V5 = old values of chart.
V6 = new measurement value

NV1 = (V1 + V2) / 2;
NV2 = (V2 + V3) / 2;
NV3 = (V3 + V4) / 2;
NV4 = (V4 + V5) / 2;
NV5 = (V5 + V6) / 2;

V1 = NV1;
V2 = NV2;
V3 = NV3;
V4 = NV4;
V5 = NV5;

Now it's ready for another measurement and then simply do the same.

This way V6 slowly gets propageted through the other values... but this is

what should happen, since you want a zoomed out view.

So I think this could work...

Let me know how it works out for you.
