Alexander Schacht presents graphical solutions on displaying quality of life data. Beside the total DLQI score the single items and subscores are of interest. The usage of colors is key to many visualisations. Irene de la Torre Arenas explained how to choose colors taking color blindness into consideration.  

A comprehensive overview of the total DLQI, its subscores and the single items was given in a slope graph nicely showing the shift between the categories over time. How applying visualisation principles can improve a graph significantly was shown with a simple histogram. Another useful display was the dot plot. Depending on the aim of the plot a heat map might be useful. For the statistically interested user an interactive chart gave a lot of detailed information combining plots in table format with a dendogram.

The new challenge will address the issue of missing data. How to display incomplete data and make missing data patterns visible.
