MATLAB stem3()

Three-dimensional stem plots shows lines extending from the xy-plane. A circle (the default) or other marker symbols whose z-position describes the data value terminates each stem.

Syntax

  stem3(Z) // It plots the data sequence Z as stems that extend from the xy-plane.  stem3(X, Y, Z) // It plots the data sequence Z at the value specified by X and Y. X, Y, and Z must be all be vectors or matrices of the same size.  stem3(…,’fill’)  // It specifies whether to color the interior of the circle at the end of the stem.  stem3(…,LineSpec) // It specifies the line style, marker symbol, and color for the stems.  h = stem3(…) // It returns handles to line graphics objects.  

Example

Create a three-dimensional stem plot to visualize the function of two variables.

  x=t, y=tsin(t)  z=e^t/10-1  for 0≤t≤6π  t=linspace(0,6*pi,200);  x=t; y=t.*sin(t);  z=exp(t/10)-1;  stem3(x, y, z,’filled’)
