Scatterplot tools• Scatterplot of experiment v. experiment:Plots intensity, geometric mean of the redand green intensities, and intensity ratio onlog-scale. The M-A M A plot can be implementedfor two-channel data as a plot of the log-ratio versus the average log-intensity.• Scatterplot of phenotype averages: Plotsaverages over experiment classes• Online demohttp://linus.nci.nih.gov/PowerPointSlides/Scatterplot.wmv70
[Optional: Hands-on instructions][Scatterplot of phenotype averages]1. Now click on <strong>ArrayTools</strong> Graphics -> Scatterplot Phenotypeaverages.2. Select the variable Dx as the phenotype class to average over, and then clickOK.3. This launches a 2-D 2 D and 3-D 3 D scatter plot.4. Right click on the 2-D 2 D plot to modify scatter plot properties, select up/downregulated genes as well as link genes in other plots.71
