For global labeling of 2D plots (also labeling of individual data points), see Labeling Plots using Label tab or Mini Toolbars.. For precise picking and labeling specific points on 2D and Contour plots, you can use the customizable Annotation tool. To change the Type of shape annotation, specified as one of these values. As Image Analyst said, you could always use text() which uses the same units as your data. the annotation and specifies properties as name-value pair arguments. annotation(lineType,x,y) creates MATLAB: Place annotations using axis coordinates from a date-axis. Simply use the xy coordinates to plot "X"'s. The lower Specify lineType as 'line', 'arrow', 'doublearrow', To automatically I see no reason why Matlab cannot allow users to specify the units in annotations which would make the tool a lot more useful. " Then, add a bent arrow to the graph by combining a line and an arrow annotation. Thanks to both of you for talking me off that ledge. To specify the text, set the String property.
