A trend chart, also called a run chart, shows data over time. This is a linear graph that allows you to track improvements by displaying data in a time sequence, usually over months. Time is generally displayed on the horizontal x-axis and the measure you are tracking is displayed on the vertical y-axis. A trend chart is a good way to evaluate at what point in time a process changed. Knowing this point in time sub- sequently enables you to determine whether improvement is actually taking place.14 Figure 13.3 shows a sample trend chart tracking nursing home resident weight loss.
