If it is a plot produced by mesh() then you cannot add an individual point to it as part of the mesh: mesh() requires that the z values be a matrix. mesh() produces a surfaceplot object. You can openfig() the .fig and findobj() on the figure looking for 'type','surface' to...

My Problem is, that I need to get a second plot next to an existing plot. I thought, that I need to get Points, that are on the plotted Line and try to calculate normal vectors that show me the new points that I need. The main Problem is, that the differences from start to end...
Add Data to Existing Polar Plot Create a cosine-pattern antenna and plot the pattern from 0° to 36°. az = [0:360]; p1 = abs(cosd(az)); Plot the polar pattern. P = polarpattern(p1); Create a second cosine-pattern antenna rotated by 60°. Add this pattern to the existing patt...

Add Text Description to Data Point Copy Code Copy Command Plot a sine curve. At the point (π,0), add the text description sin(π). Use the TeX markup \pi for the Greek letter π. Use \leftarrow to display a left-pointing arrow. Get x = 0:pi/20:2*pi; y = sin(x); plot...
plotg allows creating line plots with color gradients that are defined based on point indices (default) or a given set of values of the points.Cite As Siamak (2025). plotg (https://www.mathworks.com/matlabcentral/fileexchange/67385-plotg), MATLAB Central File Exchange. Retrieved May 9, ...
Compute an alpha shape for the point set using an alpha radius of 1. The resulting alpha shape has two regions. Get shp = alphaShape(x,y,1); plot(shp) Now add a third region to the alpha shape by adding new points directly to the shp.Points matrix. Get x3 = x1+8; y3 = y1...
