Contour plot matlab

Create matrices X and Ythat define a grid in the x-y plane.

Help Center Help Center. A surface plot 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. The color of the surface varies according to the heights specified by Z. Specify the axes as the first input argument. For example, 'FaceAlpha',0.

Centro de ayuda Centro de ayuda. Para dibujar los contornos en una altura k , especifique levels como vector fila de dos elementos [k k]. Para obtener una lista de las propiedades, consulte Contour Properties. Especifique los ejes como el primer argumento en cualquiera de las sintaxis anteriores. Inserte valores NaN siempre que haya discontinuidades en una superficie. Reemplace todos los valores de la columna 26 por valores NaN. El valor predeterminado de X es el vector 1:n. Cuando X es un vector, los valores deben ser estrictamente crecientes o decrecientes. La propiedad XData del objeto Contour guarda las coordenadas x. Tipos de datos: single double int8 int16 int32 int64 uint8 uint16 uint32 uint

Based on your location, we recommend that you select:. Specify the axes as the first argument in any of the previous syntaxes.

Help Center Help Center. A contour plot represents a 3-D surface by plotting lines that connect points with common z -values along a slice. For example, you can use a contour plot to visualize the height of a surface in two or three dimensions. You can create a contour plot with emphasis on selected contour lines by splitting the data and creating two overlapping contour plots. Choose a web site to get translated content where available and see local events and offers. Based on your location, we recommend that you select:.

Help Center Help Center. The contour lines must be long enough to fit the label, otherwise clabel does not insert a label. If you do not have the contour matrix C , then replace C with []. Click the mouse or press the space bar to label the contour closest to the center of the crosshair. Press the Return key while the cursor is within the figure window to terminate labeling. Use any of the input argument combinations in the previous syntaxes that do not include the contour object h. Use any of the input argument combinations in the previous syntaxes. For example, 'FontSize',14 sets the font size to 14 points.

Specify the options after all other input arguments. Contours of a Function Create matrices X and Y , that define a grid in the x-y plane. Based on your location, we recommend that you select:. Open Mobile Search. Smaller values produce more labels. Select the China site in Chinese or English for best site performance. Choose a web site to get translated content where available and see local events and offers. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes. To draw contour lines at a single height k , specify levels as a two-element row vector [k k]. In this case, call the peaks function to create Z. You can specify the line style, line color, or both.

Help Center Help Center. The column and row indices of Z are the x and y coordinates in the plane, respectively.

Help Center Help Center. Contours Over Discontinuous Surface. Example: contour peaks,10 draws contour lines at 10 automatically chosen heights on the peaks function. LineWidth — Line width 0. Contour line labels, specified as 'on' or 'off' , or as numeric or logical 1 true or 0 false. When Y is a vector, the values must be strictly increasing or decreasing. Use this object to set properties after displaying the contour plot. And the yellow region corresponds to heights that are greater than 3. Insert NaN values wherever there are discontinuities on a surface. No, overwrite the modified version Yes. Alternatively, you can specify some common colors by name. Ejes objetivo, especificados como objeto Axes. Then create a contour plot of that function, and display the labels by setting the ShowText property to 'on'. Example: Contours at Fifty Levels.
