So I was wondering how I would measure and or quantify the shape of a sequence of data values with two values (an entry and an exit angles to/from the max)

Say we have a set of values like:

0,5,10,5,0

If we assume the x axis incremental is by 1 and plot this on graph paper we would end up with a curve that looks like a sail bout. So we could say the entry and exit angle are say 45 degrees.

But is the data values where very small we would hardly notice any shape at all.

So I guess we would need to scale the x by the y values some how and this is where I am stuck.

Many thanks in advance IMK
