Now I would like to draw an arrow starting at 90 s, 0.04 concentration units and going to 120 s, 0.09 concentration units. E.g. or ellipse with respect to the lower left corner of the figure. a rectangle, ellipse, or text box annotation with a particular size Here's a quick illustration of what I mean. To specify the text, set the String property. By default, the units are normalized to the figure. [warning]Text annotations created using the text or gtext function are anchored to the axes. Change the color of the rectangle outline by specifying the Color property. This property affects the Position property. With a few lines of code, you can normalise your arrow object positions with respect to them. The text box uses the specified width and height and wraps text as needed. object returned depends on the first input argument. 0. You can also invoke MATLAB functions with a click on the image.
