To get an instant graph of the probability density function of your data, simply upload it with curl:

    $ curl -F 'X-axis label=@/path/to/data.txt'

That will then give you something wonderful like this distribution of file sizes on my system shown below.


Statistics is hard and I like to get to know my data. The probability density function (analytically calculated from your data using kernel density estimation) is a very easy way to see what your data looks like. How spread-out is the distribution, what shape is it, etc.

In case you were wondering, the red dots are the 1st, 10th, 25th, 50th, 75th, 90th, and 99th percentiles. The blue dots are the expectation (a kind of average) and the mode (the highest point of probability density).
