Question: Why Is My Surf Plot Black?

How do I change my surf color in Matlab?

Change the Direction or Pattern of Colors When using the default value of C=Z , the colors vary with changes in Z .

[X,Y] = meshgrid(-10:10); Z = X + Y; s = surf(X,Y,Z); xlabel(‘X’); ylabel(‘Y’); zlabel(‘Z’); You can change this behavior by specifying C when you create the surface..

How do you plot a surface in Matlab?

surf( X , Y , Z ) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y .

How do I delete an old plot in Matlab?

Direct link to this answer Click “edit plot” — the arrow next to the printer icon. Then, click on the line you want to delete and then delete it.

How do I run Matlab code?

In order to run the program, type the name of the file containing your program at the prompt. When typing the filename in the command window do not include “. m”. By pressing enter, MATLAB will run your program and perform all the commands given in your file.

How do you delete a line in octave?

There are several clearing shortcuts defined:Meta-D : clear the next word. … Ctrl-K : clear to the end of the line.Ctrl-U : clear the whole line.Ctrl-L : clear the line and the screen.

Why is my surface plot black?

The issue occurs when the grid which your surface is plotted over contains a large number of points. The lines which create the wire mesh surface are black by default and take precedence over the color map. In this situation, the wire grid is so dense that the lines form a completely black surface.

How do I remove a line from a graph in Matlab?

If you want to do it in your code you could create a seperate handle for each of your line objects and use the delete function.h(1)=plot(x,y); hold on.h(2)=plot(x,z);delete(h(2))

How do you plot a 3d surface?

There are 4 main steps:Establish the domain by creating vectors for x and y (using linspace, etc.)Create a “grid” in the xy-plane for the domain using the command meshgrid.Calculate z for the surface, using component-wise computations.Plot the surface. The main commands are mesh(x,y,z) and surf(z,y,z)

How do you plot a 3d line in Matlab?

plot3( X , Y , Z ) plots coordinates in 3-D space.To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length.To plot multiple sets of coordinates on the same set of axes, specify at least one of X , Y , or Z as a matrix and the others as vectors.
