The graph shown here is a plot of mRNA expression relative to control for two different experimental treatments.
The graph highlights Origin's ability to readily create log-scale plots using a floor of 1. The key to using this feature is to enable the appropriate check box ("Log Scale Use 1 as Floor") under Tools: Options => Graph tab.
This type of graph is frequently used when dealing with gene expression.
