The basic Time-series Explorer technique. The technique uses tightly coupled line-chart and scatter-plot views of the data. The line-chart shows gene expression against time and allows the user to select an interval. The scatter-plot summarizes the data within the selected interval representing each gene as a single point. The y-axis represents mean activity and the x-axis change in activity. Adjusting the interval forward through time causes genes to move smoothly and predictably in an anticlockwise direction as expression changes from low to rising to high falling back to low etc.
