For precise picking and labeling specific points on 2D and Contour plots, you can use the customizable Annotation tool. Unfortunately, all annotation objects take "normalized figure coordinates" as input, which is a bit awcward. No attempt has been made to compensate for this pitch motion. Im just looking for a way to place 'X's at specific xy coordinates to signify that those points are no longer being considered for my calculations?? The video shows that the car pitches slightly up and down, which changes the pitch angle. or 'textbox'. Use an to modify properties of The object. If you wanted rectangles for whatever reason, , [x-widthHeight(1)/2, y-widthHeight(2)/2, widthHeight]). You can specify several name and value See the annotation property pages for a list of properties for each type of annotation. Properties You Can Modify . Specify lineType as 'line', 'arrow', 'doublearrow', Now, as one can see the x-axis uses datenum-numbers. Then, add a bent arrow to the graph by combining a line and an arrow annotation. Just wondering but I wanted to put annotations/text boxes at specific coordinates but when I read up on the page I saw that the values of x and y in the 'dim' vector must be between 0 and 1. To specify the text, set the String property.
