Create Feather Plot Using Cartesian Values

Create a feather plot by specifying the components of each arrow as Cartesian values. The nth arrow originates from n on the x-axis.

t = -pi/2:pi/8:pi/2;
u = 10*sin(t);
v = 10*cos(t);
feather(u,v)

Create Feather Plot Using Polar Values

Create a feather plot using polar coordinates by first converting them to Cartesian coordinates.

To do this, create vectors with polar coordinates. Convert them to Cartesian coordinates using the pol2cart function. Then, create the plot.

th = -pi/2:pi/16:0;
r = 10*ones(size(th));
[u,v] = pol2cart(th,r);
feather(u,v)

Create Feather Plot Using Complex Values

Create a vector of complex values. Then, display them using a feather plot. The real part determines the x-component of each arrow, and the imaginary part determines the y-component.

Z = [2+3i -1-3i -1+i 2i 3-4i -2-2i -2+4i 0.5-i -3i 1+i];
feather(Z)

Specify Color of Feather Plot

Create a feather plot with red arrows.

t = -pi/2:pi/8:pi/2;
u = 10*sin(t);
v = 10*cos(t);
feather(u,v,'r')

Specify Line Width and Color of One Arrow

Specify the line width and color of a single arrow by assigning the arrow to a variable and then setting its properties. To do this, first create a feather plot and return an array of Line objects.

t = -pi/2:pi/8:pi/2; u = 10sin(t); v = 10cos(t); f = feather(u,v);

Assign the first arrow to a variable. The first arrow corresponds to the first elements of u and v. Then, change the line width and color.

f1 = f(1);
f1.Color = 'r';
f1.LineWidth = 2;

Specify Axes for Feather Plot

Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 1-by-2 tiled chart layout. Call the nexttile function to create an axes object and return the object as ax1. Create the left plot by passing ax1 to the feather function. Add a title to the plot by passing the axes to the title function. Repeat the process to create the right plot.

tiledlayout(1,2)

% Left plot
ax1 = nexttile;
t = 0:pi/8:pi/2;
u1 = 10*sin(t);
v1 = 10*cos(t);
feather(ax1,u1,v1)
title(ax1,'Left Plot')

% Right plot
ax2 = nexttile;
u2 = zeros(5,1);
v2 = [1 -2 3 -4 5];
feather(ax2,u2,v2)
title(ax2,'Right Plot')
