Help Center Help Center. The plot is formed by joining adjacent points with straight lines. Surface plots are useful for visualizing matrices that are too large to display in numerical form and for graphing functions of two variables. Mesh plots are wire-frame surfaces that color only the lines connecting the defining points. Surface plots display both the connecting lines and the faces of the surface in color.

Centro de ayuda Centro de ayuda. Especifique los ejes como primer argumento de entrada. Por ejemplo, 'FaceAlpha',0. Para obtener una lista de las propiedades, consulte Surface Properties. Cuando usa un color real, si Z es m por n , CO es m por n por 3. Cree una superficie semitransparente especificando el par nombre-valor FaceAlpha con 0. Por ejemplo, oculte los bordes estableciendo la propiedad EdgeColor. Si no especifica valores para X e Y , surf utiliza los vectores 1:n y 1:m. La propiedad XData del objeto Surface guarda las coordenadas x. Tipos de datos: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 categorical datetime duration. La propiedad YData del objeto de superficie guarda las coordenadas y. Coordenadas z , especificadas como matriz. Z debe tener al menos dos filas y dos columnas. La propiedad ZData del objeto de superficie guarda las coordenadas z. Para usar colores del mapa de colores, especifique C como matriz.

Specify the colors for a surface plot by including a fourth matrix input, C.

Create three matrices of the same size. Then plot them as a surface. The surface plot uses Z for both height and color. Specify the colors for a surface plot by including a fourth matrix input, C. The surface plot uses Z for height and C for color. Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum. When you use a colormap, C is the same size as Z.

Given a matrix, and optionally the grid of X-axis and Y-axis values, it is possible to create a contour plot in R with the contour function. The nlevels argument controls the number of contour levels to be drawn. The default value is You can change the color of the contour lines with col , passing a color or a color palette, such in the example below, which draws contours for the volcano data set. If you want to overlay contour lines over a scatter plot you can use the kde2d function from MASS to calculate the kernel density estimate of the variables as shown in the example below. A similar function to contour is filled. The function behaves almost the same as the function from the previous section. The color palette can be set with color. The plot. Facebook logo.

Help Center Help Center. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y. The function uses the default direction for the light source and the default lighting coefficients for the shading model. This sets the color data for the surface to be the reflectance of the surface. Because of the way surface-normal vectors are computed, surfl requires matrices that are at least 3-by

For each grid point on the surface, C indicates a color in the colormap. When you plot multiple surfaces over different intervals in the same axes, the axis limits adjust to include all the data. If you do not specify the colors, then Z also specifies the surface colors. Vector of form [min max] — Use the interval [min max] for both x and y. Control the resolution of a surface plot using the 'MeshDensity' option. Name-value arguments must appear after other arguments, but the order of the pairs does not matter. For example, a by image require you to set the NumOctaves parameter, less than or equal to 2. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y. Plotting interval for u and v , specified in one of these forms: Vector of form [min max] — Use the interval [min max] for both u and v Vector of form [umin umax vmin vmax] — Use the interval [umin umax] for u and [vmin vmax] for v. Historial de versiones Introducido antes de Ra.

Create three matrices of the same size. Then plot them as a surface. The surface plot uses Z for both height and color.

The first page of the array indicates the red component for each color, the second page indicates the green component, and the third page indicates the blue component. You have a modified version of this example. Open Live Script. Y — Coordenadas y matriz vector. Specify Surface Properties. Example: Illustrating the Use of meshgrid. Values between 0 and 1 are semitransparent. Alternatively, you can specify some common colors by name. Especifique los ejes como primer argumento de entrada. MATLAB then constructs the surface plot by connecting neighboring matrix elements to form a mesh of quadrilaterals. Vector of form [umin umax vmin vmax] — Use the interval [umin umax] for u and [vmin vmax] for v. Use this value to view curved surfaces. The CDataMapping property of the surface object controls how the values in C correspond to colors in the colormap.
