I'm pretty sure it's just a list of employees sorted by how much sick time is taken, so the X-axis is an "employee index number".

More interesting (and pertinent when trying to find a pattern in this data) would be a histogram for sick time taken. Trying to fit a curve to the graph as-is isn't useful, because the X-axis doesn't represent anything meaningful.

This is my thought as well. So you fit a curve to a sorted list of each employees sick time. Does this give you any additional insight? So it follows a log function. Does that mean anything?

If you do a histogram and fit a function you get something that could conceivably be interpreted as a probability distribution function, you might be able to say something about predicting the sick time a given employee will take and the uncertainty of your prediction.

But I honestly don't see what visualizing the data in the method of the post, or fitting a function to it contributes. Hope that doesn't violate the new no negativity policy of HN.
