Series Keywords: learning curve, bell curve, well curve, process, cycle

Segmented bell curves extend the uses of the solid bell curves (cn010). The example shows volumes or concentrations of different classifications. The segments range from 1 to 31, so they can also be used to illustrate days, weeks, months, quarters, years, and many other units of time on the x axis. Segments can also be used to create asymmetrical divisions in the bell curve: use the same fill and line color to create the appearance of a solid curve, then group and stretch the desired segments, and finally redistribute the segments so they appear continuous once again – the curve is asymmetrical. Gaps and chasms can be created by either deleting some of the segments or by moving blocks of segments to the right or left. The many layouts create the potential for many uses.

Notice that this bell curve does not start at "0" on the Y axis. This implies that the process or evaluation does not start and end at "nothing." This is significant in a learning curve, because the bell implies that there is some inherent knowledge at the beginning of the learning curve and there will be still more to learn at the end of the learning curve. It is also significant at the beginning of a process: it implies that, perhaps, groundwork for the process has been performed at the front end and ongoing refinements are needed at the end of the process. These are subtle distinctions, but they should not be overlooked.
