I tried using the packages available on the matlab file exchange. If you specify this property as a function handle or cell array, you can access the object that is being deleted using the first argument of the callback function. Run the command by entering it in the matlab command window. Line properties control the appearance and behavior of a line object. Arrow3p1,p2 draws lines from p1 to p2 with directional arrowheads. The display of the line object, p, shows the most commonly used. On my matlab r2007a the line of the arrow is visible after the tip of the arrowhead in 2d plots. Note also that the units of these coordinates are specified in normalized figure units. The viscircles function does not clear the target axes before plotting circles.

For example, the plot function returns a chart line object. All graphics objects have properties that you can view and modify. You can add an arrow to a figure by using the function annotation. Starting in r2014b, you can use dot notation to query and set properties. I even tried manually creating an arrow in the matlab figure editor, but when i adjust the line width, the arrow looks like this. Textarrow properties control the appearance and behavior of a textarrow object. To illustrate, this example creates a new figure and then loops, drawing a set of circles with each iteration, clearing the axes each time. You can control the behavior and appearance of a particular graphics object by setting its properties.
