Before plotting, JAMES sorts the observations on the x-variable. When the x-variable is age, the plotted curve will be automatically sorted in age, as expected.

However, the order of the x-variable in the weight-for-height plot may differ from the age order. This occurs when the child is measured to be shorter than previously. In that case, the lines that connect the dots suggest a wrong age order.

Weight-for-height data should not be sorted on height, but on age.
