http://younglab.wi.mit.edu/expression/foldchange.html WebFold change is the number of times a gene is over-expressed (or under), compared to some baseline (your control, or the reference gene, etc.). A sample could be 100X more expressed, or 1/100th the expression of the baseline. Because this is hard to show in a graph, we plot in log. It "flattens" the data out to make it more visible.
