Code Example 1: Basic Arrow Addition Let’s consider a simple example where we have a plot, and we want to add an arrow pointing to a specific data point. Assume we have the following data: % Creating a simple plotx=1:0.1:5;y=sin(x);plot(x,y,'LineWidth',2);% Adding a basic ...

I need help to draw an arrow to a polar plot (e.g. to indicate resultant vector). I am using the new polarplot() function as opposed to the old polar() or polarhistogram() functions. Thus I cannot (to my knowledge) use functions like quiver because this would be plotted onto cartes...

instead of an arrow on the tip. Use a marker of '.' to specify no marker at all. See PLOT for other possibilities. quiver3(...,'filled') fills any markers specified. quiver3(AX,...) plots into AX instead of GCA. H = quiver3(...) returns a quiver object. ...
