Interobserver agreement plot.<br>
Horizontal axes represent average, vertical axes represent difference from the mean. Individual measurements of observers represented by black dots. Note some dots have been superimposed.<br>
Horizontal lines indicate upper and lower limits of agreement with the mean and a line of zero difference. Dashed lines correspond to the confidence intervals for the limits of agreement.
