• Markowitz 1952I'm trying to get some "pretty" arrows for graphs and other uses in Sage. One of the problems we've been having with the FancyArrow and YAArrow is that the arrow is skewed when the aspect ratio is not 1:1 and it is scaled along with the plot. Data units per arrow length unit, e.g., m/s per plot width; a smaller scale parameter makes the arrow longer. If None, a simple autoscaling algorithm is used, based on the average vector length and the number of vectors. The arrow length unit is given by the scale_units parameter scale_units: None, or any of the units options.

When plotting 3D arrows, there are no arguments in Axes3D.quiver() that can be used to changed the shape/size of the head of a 3D arrow. Nor is there any related attribute in Line3DCollection that can be used. The size of a 3D arrow head seems to be dependent on the scale of the plot, i.e., xlim, ylim, and zlim. Data units per arrow length unit, e.g., m/s per plot width; a smaller scale parameter makes the arrow longer. If None, a simple autoscaling algorithm is used, based on the average vector length and the number of vectors. The arrow length unit is given by the scale_units parameter scale_units: None, or any of the units options.

The resulting arrow is affected by the axes aspect ratio and limits. This may produce an arrow whose head is not square with its stem. To create an arrow whose head is square with its stem, use annotate() for example:

I agree with Aamir that the submission arrow.m from Erik Johnson on the MathWorks File Exchange is a very nice option. You can use it to illustrate the different methods of vector addition like so: Tip-to-tail method: example script for matplotlib(2.0.0) quiver 3d custom coloring for each arrow - testColorfulQuiver3d.py I wanted to visualize better the generated 3D quiver plot by specifiing a custom color for each arrow as follows: vector3d(x, y, z) -> rgb(x/x_max, y/y_max, z/z_max) where all values are absolute values.
