A special case of importance in the display of simultaneous intervals SCLs or SPLs arises when the results of measurements or observations only at corresponding values of x are to be displayed with the intent of understanding what they say about 1 the plausibility of the existence of a smooth dependence on x of the underlying value ave yx the average that would have been found were it possible to repeat the measurement y very many times for the same x, and 2 which smooth dependencies seem to be plausible in view of the data. The aperture pencil point techniques of Hoaglin and Tukey suggest very useful approaches, although, as reported in that reference. These techniques have so far been directed toward the combination of SCLs and ICLs. The present account builds on all the insights thus developed, seeking for simplicity and treating related problems as they arise.
