MATLAB provides its user with a basket of functions and tools, in this article we will understand About 3-dimensional plots in MATLAB.
We must pass the data’s input matrix, plotted as heights on the z-axis in a 3D plane. We can use Matlab’s built-in function bar3() to plot a bar graph in a 3D plane. Use the bar3() Function to Create a 3D Bar Graph in MATLAB clcĬheck this link for more details about the quiver3() function. In the case of vector, we can use the quiver3() function, which will plot the magnitude and direction of the vector.įor example, let’s create a matrix and plot it on a 3D plane with direction. We can create a 3D plot of scalar data using the plot3() function, but we cannot plot vector data using the plot3() function because the function will not plot the direction of the vector. A scalar consists of only magnitude, but a vector contains magnitude and direction. Matlab’s built-in function quiver3() can be used to plot a 3D quiver or vector plot. Use the quiver3() Function to Create a 3D Quiver or Vector Plot in MATLAB For example, let’s plot a helix in 3D using the plot3() function.Ĭheck this link for more details about the plot3() function. We have to pass three coordinates, x, y, and z, to plot the data on a 3D plane. We can plot data as a line, aka a continuous plot, and as points, aka a discrete plot. The only difference is that the plot3() function plots data on a 3D plane. The plot3() function is similar to the plot() function. We already know about the plot() function in Matlab, which is used to plot data on a 2D plane. Use the plot3() Function to Create a 3D Plot of Point or Line in MATLAB clcĬheck this link for more details about the contour3() function. The colder color corresponds to low values, and the hotter color corresponds to high values.įor example, let’s plot a 3D contour plot of a sphere using the sphere() and the contour3() function.
The color given to the line depends on its value. A contour plot is a plot of isolines with different colors according to values. We can use Matlab’s built-in function contour3() to create a 3D contour plot. Use the contour3() Function to Create a 3D Contour Plot in MATLAB In the case of two input vectors, the third coordinate z will be taken from the indices of the first two coordinates.įor example, let’s plot a scatter plot in a 3D place using the scatter3() function.Ĭheck this link for more details about the scatter() function. In the case of three inputs, the first vector contains the x coordinates, the second contains the y coordinates, and the third contains the z coordinates. We can give two or three input vectors to the scatter3() function. This function is the same as the scatter() function, though it plots the given data in a 3D plane. If we want to create a 3D scatter plot, we can use the scatter3() function.

The given matrix will be plotted on the z-axis as heights on a three-dimensional plane.įor example, let’s create a matrix Z and plot it on the surface plot using the mesh() function in Matlab. The x and y coordinates will be from the indices of the given matrix. The mesh() function will plot the given matrix along the z-axis using the default value for the x-y coordinates. We can pass the matrix inside the mesh() function as a function that we want to plot in the 3D plane. Matlab’s built-in function mesh() creates the surface plots on a 3D plane. Use the mesh() Function to Create Surface Plots in MATLAB This tutorial will discuss creating 3d plots using the mesh(), scatter3(), contour3(), plot3(), quiver3(), and bar3() functions in MATLAB.
