1. A method of coordinating display of multiple data groups, the method comprising: generating, on a computer display device, a timelined data output diagram that includes a displayed metric value axis for each of the data groups, wherein each of the metric value axes originate at a common point and extend radially from the common point; generating, on the computer display device, a timeline object that provides a user input interface, wherein the timeline object presents a time interval display that is set based on the data groups; displaying, on the computer display device, a first marker within the timelined data output diagram, wherein the first marker comprises a first display symbol associated with a metric-specific limit value, and wherein the first marker is positioned on one or more of the metric value axes based on where along a metric value axis a data group value exceeds a metric-specific limit; displaying, on the computer display device, a second marker at a position within the time interval display that corresponds to a time value at which the data group value exceeded the metric-specific limit, wherein the second marker comprises a second display symbol that substantially matches the first display symbol; receiving a first user input at a selected start time position within the timeline object; in response to said first user input, displaying a start time indicator on said timeline object at the selected start time position; receiving a second user input at a selected stop time position within the timeline object; in response to said second user input, displaying a stop time indicator on said timeline object at the selected stop time position; and in response to the first and second user inputs: changing the appearance of the timeline object between the start time indicator and the stop time indicator; identifying one or more marginal criteria values for each of the data groups and inserting markers corresponding to the marginal criterial values on the timeline object; and plotting on each of the metric value axes: a boundary value and a marginal criteria value for a respective data group within the time interval between the start time indicator and the stop time indicator, wherein the boundary value, the marginal criteria value, and the metric-specific limit are each different value types; and a statistic value for a respective data group, wherein the statistic value is determined based on data group values associated with times between time values corresponding to the start time indicator and the stop time indicator.
