It uses matplotlib's plot_surface function instead of plot_trisurf. Basically you want to reshape your x, y and z variables into 2d arrays of the same dimension. To add the fourth dimension as a colormap, you must supply another 2d array of the same dimension as your axes variables.

Oct 22, 2011 · To create the plot you want, we need to use matplotlib's plot_surface to plot Z vs (X,Y) surface, and then use the keyword argument facecolors to pass in a new color for each patch.

import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D from matplotlib import cm from matplotlib.colors import ListedColormap ## The following code creates the figure plotting function def MakePlot(xx,yy,zz,ww,cmapO=cm.jet): ##Create Custom Colormap with Alpha varying depending on the functions behavior.

Mar 9, 2024 · In Python’s Matplotlib, the scatter() function’s ‘c’ parameter can be used to set the color of each point. A colormap can translate the numerical value of the fourth dimension to a specific color on the plot.

Matplotlib has a number of built-in colormaps accessible via matplotlib.colormaps. There are also external libraries that have many extra colormaps, which can be viewed in the Third-party colormaps section of the Matplotlib documentation.

Aug 23, 2022 · It uses matplotlib's plot_surface function instead of plot_trisurf. Basically you want to reshape your x, y and z variables into 2d arrays of the same dimension. To add the fourth dimension as a colormap, you must supply another 2d …

Dec 31, 2024 · To make a 4D plot using Matplotlib, you can use the mplot3d toolkit that comes with Matplotlib. This toolkit allows you to create three-dimensional plots, but you can also use it to plot four-dimensional data by adding a color dimension.
