A variation on a theme of the above is to calculate and plot3/fill3 the first case then write the labels before you build the loop. The short names and long names are MATLAB strings that specify one of eight predefined colors. You can also use fill3: fill3(A,B,C) Also you can use patch: patch(A,B,C,[0,6]) %fourth argument gives a gradient of colors, alternatively you can use 'red' or 'blue' Or as mentioned in the comments, you can use the following: SearchYou are not providing surface data to fill3, just points, so there is no clearly defined triangulation, and it is trying to fill between consecutive vertices (which may be in no particular order). Thus, I have written something like: axes01 = fill3(X1, Y1. However, the border line color is always black. We can clearly see that the point of the polygon to be filled are ordered in a.

You can recreate the. Higher Education Comment Card. Include a third data input to vary marker size and represent a third dimension. If X, Y, or Z is a matrix, fill3 creates n polygons, where n is the number of columns in the matrix. . It is my understanding that you want to generate a similar shape by using “surf” plot as “fill3” plot does but i t is p ossible that the surface plotted by the surf function appears different from the surface plotted by fill3 because they use different algorithms to generate the surface. The XData, YData, and ZData properties on a Patch object created by the fill or fill3 functions return the coordinates using the original input data type, rather than returning them as double. 0. To plot one region, specify X, Y, and Z as vectors. 可以使用上述语法中的任何输入参数组合来指定补片。. Contour Plots.
