Visualizing Uncertainty in Dynamic Variables

How to visualize an uncertainty in a time-dependent variable according to the principles of uncertainty visualization?

We have a trajectory is a time-space, but we don’t know exactly where it is. One of the simplest way way to visualize such data is a ‘spaghetti-plot’:

Here each line in Figure is one possible trajectory. This Figure is already very efficient, but it may be influenced by the choice of visualized possibilities. For example:

Visualizing Uncertainty in Dynamic Variables


I have described the swine flu data in the previous post, now I’m going to cover the presentation of the results in my paper. The results are a set of posterior distributions. The application details do not matter here. Here is the old picture from my master’s thesis: thesis Posterior distributions were visualized with histograms. The bins in the histogram were not predefined: they were shifted so that the mode of the original distribution would be exactly in the middle of the bin. I used different colors to emphasize that the figure show three parameter families. Now I would sort the rows according to some meaningful attribute and add a grid.

Swine flu epidemic in Finland 2009-2011: Data

In the spring 2009, a new influenza strain A(H1N1)pdm09 aka “swine flu” appeared, causing the world-wide pandemic. Luckily, swine flu happened to be a very mild infection, and the harm was insignificant. I have studied the Finnish branch of the global pandemic since 2010. I’ve made my master thesis about it, published a paper and going to submit another paper soon. This is a story about the data visualization in my upcoming paper. Next post will be devoted to the visualization of the results.

I will start with the data visualization I made 4 years ago for my Master’s thesis:


(A) The number of new cases per week. The horizontal axis shows the week, from week 18 of 2009 to week 5 of 2010. The data consist of several layers: cases identified with A influenza, cases specifically identified with A(H1N1) influenza; cases identified with A(H1N1) influenza and assigned to hospital. (B) The total number of cases by age group. (C) The number of cases per 10000 individuals by age group. (D) The total number of cases by region. (E) The number of cases per 10000 individuals by region. 

I still think it was a nice visualization (especially I love the idea of showing absolute values with bars and relative values with ticks), but now I’m able to see a lot of mistakes.
