POMathematical library to compare simularities in graphs of data for a high level language (eg. Javascript)?

Body
copied!<p>I'm looking for something that I guess is rather sophisticated and might not exist publicly, but hopefully it does.</p> <p>I basically have a database with lots of items which all have values (y) that correspond to other values (x). Eg. one of these items might look like:</p> <pre><code>x | 1 | 2 | 3 | 4 | 5 y | 12 | 14 | 16 | 8 | 6 </code></pre> <p>This is just a a random example. Now, there are thousands of these items all with their own set of x and y values. The range between one x and the x after that one is not fixed and may differ for every item.</p> <p>What I'm looking for is a library where I can plugin all these sets of Xs and Ys and tell it to return things like the most common item (sets of x and y that follow a compareable curve / progression), and the ability to check whether a certain set is atleast x% compareable with another set.</p> <p>With compareable I mean the slope of the curve if you would draw a graph of the data. So, not actaully the static values but rather the detection of events, such as a high increase followed by a slow decrease, etc.</p> <p>Due to my low amount of experience in mathematics I'm not quite sure what I'm looking for is called, and thus have trouble explaining what I need. Hopefully I gave enough pointers for someone to point me into the right direction.</p> <p>I'm mostly interested in a library for javascript, but if there is no such thing any library would help, maybe I can try to port what I need.</p>
