An easy way to compare price dynamic of different coins
Jul 28, 2017 · 1 min read
A standard coin time series graph like the one below has a significant drawback: it is very difficult to see the synchronized price movements.

One of the easiest ways to solve this problem is to use a method of normalization called Feature scaling. This is a very simple method used to standardize the range of independent variables.
The simplest method is to scale the range in [0–1] or [−1–1]. You can choose any range you prefer.
The general formula is the following:
X = (x — min(x))/ (max(x) — min(x))
where x is an original value and X is the normalized value.
The normalized graph looks like this:
