This months challenge was to display diary data on six symptoms to track disease progression over time. Zak Skrivanek is presenting the proposed visualisations and discusses the impact of colour selection and arrangement of multiplots. Visualisations are available on the Wonderful Wednesday blog

The first plot is a stacked bar chart showing the different symptoms on top of each other. With six symptoms the coloring gets more difficult. Zak highligths ways to increase accessibility for color-blind users. And with 100 time points the plot is actually a stacked area chart. The next plot uses vertical time axes to align the plots for the two treatments and added a plot for treatment differences. The symptoms are combined as multiplot. In the arrangemnent of the plots enclosure and proximity can improve readability. The new challange is on a simple CGI data set. See the Wonderful Wednesday homepage for more detail.
