How to "zoom" or "scale"

[svoip]

Suppose I have value set of values that fluctuate between 0 and 1. The timeline goes up and down (lowest value 0) correctly.
Now suppose my next value is 50. I would like the timeline to "zoom out" (or "scale up") so that to place the next incoming value on screen proportinate to the previous numbers.
There is no way to know in advance what value I will receive next, it maybe be a negative value or some higher number as 500.

Is there a built-in solution for this? If not, how could I go about it? Many thanks.
