### How does the surface plot in MATLAB surf work?

## How does the surface plot in MATLAB surf work?

surf (Z) creates a surface plot and uses the column and row indices of the elements in Z as the x – and y -coordinates. surf (Z,C) additionally specifies the surface color. surf (ax, ___) plots into the axes specified by ax instead of the current axes.

### How to plot a triangulation in 3-D?

Create a set of 3-D points and compute the Delaunay triangulation using the delaunay function. Plot the surface defined by the triangulation. Alternatively, you can create and plot a triangulation object. Triangle connectivity, specified as a 3-column matrix where each row contains the point vertices defining a triangle face.

**How to plot a triangular surface using trisurf?**

trisurf(T,x,y,z) plots the 3-D triangular surface defined by the points in vectors x , y, and z, and a triangle connectivity matrix T.

**What is a RGB triplet in MATLAB trimesh?**

Face color, specified as the comma-separated pair consisting of ‘FaceColor’ and a color name, an RGB triplet, or ‘none’. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color.

## Is it possible to produce a 3D surface plot with log scale?

Is it possible to produce a 3D surface plot of my XYZ data using log scales, ideally I’d like X & Z on linear scales and Y on a log scale? Any help would be greatly appreciated. Please forgive any obvious mistakes in the above example, as mentioned I don’t have my exact code to have and so have altered a matplotlib gallery example from my memory.

### How to plot coordinates on a log scale?

The loglog function plots coordinates on a log scale by setting the XScale and YScale properties of the axes to ‘log’. However, if the axes hold state is ‘on’ before you call loglog, those properties do not change, and the plot might display on a linear or semilog scale.

**How to create a loglog graph in MATLAB?**

loglog (ax,…) creates the line in the axes specified by ax instead of in the current axes ( gca ). The option ax can precede any of the input argument combinations in the previous syntaxes. h = loglog (…) returns a column vector of chart line objects.

How does the surface plot in MATLAB surf work? surf (Z) creates a surface plot and uses the column and row indices of the elements in Z as the x – and y -coordinates. surf (Z,C) additionally specifies the surface color. surf (ax, ___) plots into the axes specified by ax instead of the current…
