A screenshot of the DiscoverySpace Scatterplot. To use the Scatterplot the user must define a comparison between two sets of tag sequences. For this example the researcher has constructed a comparison of one normal pancreas library on the x-axis versus two cancer libraries on the y-axis. This comparison has then been viewed in the Scatterplot and the researcher has selected those tags that are up- and down-regulated with a confidence threshold of 95% or greater (marked in red). Selected tags can be dragged out of the chart and isolated into their own dataset 'Up & down regulated pancreas' for further investigation.
