Create 3-D Comet Plot

Create a comet plot of the data in z versus the data in x and y. Use the peaks function to load x, y, and z data in matrix forms. Convert the data into vector arrays. Then, plot the data.

  [xmat,ymat,zmat] = peaks(100); 
xvec = xmat(:);
yvec = ymat(:);
zvec = zmat(:);
comet3(xvec,yvec,zvec)
fig2plotly()

Control Comet Body Length

Create a comet plot and specify the comet body length by setting the scale factor input p. The comet body is a trailing segment in a different color that follows the head before fading.

Use the peaks function to load x, y, and z data in matrix forms. Convert the data into vector arrays. Specify p as 0.5 so that the body length is 0.5*length(y). Then, plot the data.

  [xmat,ymat,zmat] = peaks(100); 
xvec = xmat(:);
yvec = ymat(:);
zvec = zmat(:);
p = 0.5;
comet3(xvec,yvec,zvec,p)

Plot Data in Specified Axes

Create two comet plots in a tiled chart layout by specifying the target axes for each plot.

Use the peaks function to load x, y, and z data in matrix forms. Convert the data into vector arrays. Specify the body length scale factor p as 0.25 so that the body length is 0.5*length(y).

  [xmat,ymat,zmat] = peaks(50); 
xvec = xmat(:);
yvec = ymat(:);
zvec = zmat(:);
p = 0.25;

Store the two Axes objects as ax1 and ax2. Specify the target axes for each comet plot by including the Axes object as the first input argument to comet.

  tiledlayout(1,2);
ax1 = nexttile;
ax2 = nexttile;
