You can click the right mouse button over the graphs to display DataMontage's context menu to display the graph key, zoom in, fix reference lines, or invoke the non-linear display. You can click the left mouse over any graph to display a highlight line that indicates the selected time in every graph. This feature helps you correlate data across graphs at the same time. You can quickly measure the time interval between two points in time by clicking the mouse over one point in time and then moving the mouse to the second point in time. The time interval is automatically calculated and displayed in the tooltip.
