3 D plot in MATLAB is a tool which is very helpful in visualizing the behavior of data. It also tells us visually, how a particular function is changing when it is supplied with different values. surf (X,Y,Z,C) additionally specifies the surface color. The color of the surface varies according to the heights specified by Z. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y. Conclusion – 3D Plots in Matlabĭata visualization becomes a very powerful technique when we have to understand how our data is behaving. surf (X,Y,Z) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors. In the above figure, we can clearly see the Gouraud effect. The x, y, z values can be number, duration, and DateTime, etc. This function helps in creating flat shaped and Gouraud polygons (to get different shades of light).įill3(X, Y, Z, C): It helps in creating filled polygons with vertices x, y, z. Contour lines are selected by MATLAB automatically.ĭefine contour levels as 30, and display the results within x and y limits.ģD quiver plot creates vectors with components (u,v,w) at the points (x,y,z), where u, v, w, x, y, and z are real values. CAREFUL One of mesh and surf may be more appropriate for different graphs.
mesh(x,y,z) check out the difference in the graphs Adding axes labels, titles. We could have equally used the following command. The x & y coordinates in the plane are column and row indices of Z. xdlinspace(-1,1) ydlinspace(0,2pi) x,ymeshgrid(xd,yd) zx.cos(y) surf(x,y,z) Using MESH. For the specific size of the circle, we will have to define A as a vector.ĭefine a vector to specify the marker sizes.Ĭontour3(Z): Z is a matrix and this function will create a 3-D contour plot which will have the isolines of matrix z will have the height details of x and y plane. If A is scalar, the size of the circles will be equal. For instance, calculate z x e - x 2 - y 2. Scatter3( X, Y, Z, A, C): This function will create a plot with a circle that will have size A from the argument. Three-dimensional plots typically display a surface defined by a function in two variables, z f ( x, y ). Scatter3( X, Y, Z ): This function will create circles at the vector locations of x, y, and z.
Plot3(X1, Y1, Z1,…, Xn, Yn, Zn): This function will plot multiple coordinates for the same set of axes. Plot3( X, Y, Z, LineSpec): This function will create the plot using the specified line style, marker, and color. Plot3(x,y,z): If x,y,z are vectors of the same length, then this function will create a set of coordinates connected by line segments. If we specify at least one of x, y or z as vectors, it will plot multiple sets of coordinates for the same set of axes. Plot3 helps in creating 3D lines or Point Plots. Types of 3D Plots in MATLABīelow we have discussed the types of 3D plots in MATLAB used in computing. Plots can be created using graphic functions or interactively using the MATLAB Desktop. Data plots have a number of uses from comparing sets of data to tracking data changes over time.Data visualization is very powerful in getting the look and feel of the data in just one glance.Plots are created for data visualization.MATLAB provides its user with a basket of functions and tools, in this article we will understand About 3-dimensional plots in MATLAB.
