You have to invest significant amounts of brainpower and time editing the chart to align with your needs. When we have a huge dataset of three-dimensional variables, and we plot its figure then it looks very scattered, and this is called a 3D scatter plot. Interpolate a regular mesh for your scattered points: You can use the TriScatteredInterp function to create an interpolant that you can evaluate at a given set of regularly spaced grid points, then plot the interpolated 3-D surface using the function MESH. Well use the rgl package, which provides an interface to the OpenGL graphics library for 3D graphics. Excel produces pretty basic Scatter Plot Charts.First, you need to go to the settings and toggle the option 'Labeling: No new object'. The default representation of points is big solid balls each with a label. However, I personally do not like it for a scatterplot. Trimesh(tri,x,y,z) % Plot the mesh in 3-D Creating a scatterplot is as easy as: select the three columns, right click, choose 'create list of points'. In the video, this is done via a formula. Select 3D Scatter Plots from the MAKE A PLOT button on menu bar. Once your X and Y data are properly prepared (in a column and a row respectively), you can enter the Z data in the cells corresponding to each X and Y value. ![]() Tri = delaunay(x,y) % Create a 2-D triangular mesh This video contains a tutorial for creating 3d graphs in Excel. Plot a triangular mesh: You can connect your x and y points into a 2-D triangular mesh using the function DELAUNAY, then plot a 3-D mesh using the function TRIMESH:.To plot this surface as a mesh, you have to define some sort of connectivity between them. Go to the Design tab and click Select Data. This is a guess, but it sounds like what you actually have is a set of x, y, and z data that represent 3-D points scattered in space that lie on a surface. The scatter plot for your first series will be placed on the worksheet. You're replicating the vectors x and y to create a set of matrices X and Y when you use MESHGRID, and since z is still a vector, and not a matrix of the same size as X and Y, you can't plot a mesh. Your variable Z is still a column vector, since size(test,2) is 3 and thus the column index 3:size(test,2) is still just 3. ![]()
