A nomogram is a chart that displays values of three related variables in vertical columns in such a way that when a ruler is placed across values in any two columns, the corresponding value of the variables in the third column can be read directly from the chart. A common application is a display of heights, weights, and body-mass indexthe latter being mathematically computed from height and weight and, in practice, can be read from the nomogram chart to derive the value for individual patients or clients in a doctor's office.
