Fig. 3. Graphical analysis: scatterplots.
Scatterplot showing relationship between IL6 and IL10 Bioplex Cytokine Assay data for patients infected with Dengue Fever (in the raw format). From this plot, one might conclude that the spot at (~125,~20) is an outlier as it is distinctly different from all other values. One would specifically need to check the IL6 value as that seems the one that is different from the others (a value of 20 for the IL10 seems to fit with the others).
