Help Center Help Center. The column and row indices of Z are the x and y coordinates in the plane, respectively. Specify levels as a scalar value n to display the contour lines at n automatically chosen levels heights. To draw the contour lines at specific heights, specify levels as a vector of monotonically increasing values. To draw the contours at one height k , specify levels as a two-element row vector [k k].

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

Main Content. If Contour plot matlab contains values that are smaller than the lowest level displayed in the plot, the region between the lowest level and the smallest Z -value is white.

Help Center Help Center. To use the same interval for both x and y , specify xyinterval as a two-element vector of the form [min max]. To use different intervals, specify a four-element vector of the form [xmin xmax ymin ymax]. For example, '-r' specifies red lines. Use this option after any of the previous input argument combinations. Use fc to query and modify properties of a specific FunctionContour object.

Create matrices X and Y , that define a grid in the x-y plane. Define matrix Z as the heights above that grid. Then plot the contours of Z. Define Z as a function of X and Y. In this case, call the peaks function to create X , Y , and Z. Then plot 20 contours of Z. Define Z as a function of two variables, X and Y. Then create a contour plot of that function, and display the labels by setting the ShowText property to 'on'. Create a contour plot of the peaks function.

No, overwrite the modified version Yes. To fix this issue, increase 'MeshDensity' to in the second plot. When Y is a matrix, the values must be strictly increasing or decreasing along one dimension and remain constant along the other dimension. When X is a vector, the values must be strictly increasing or decreasing. The default is Example: contourf peaks,[-4 0 4] draws contour lines at 3 specific heights on the peaks function: -4 , 0 , and 4. Target axes, specified as an Axes object. LabelSpacing — Label spacing default scalar. This matrix must have at least two rows and two columns, and it must contain at least two different values.

Description A contour plot displays isolines of matrix Z. Label the contour lines using clabel.

Define Z as a function of two variables, X and Y. LineSpec — Line style and color character vector string scalar. The white region corresponds to the heights less than 2. Highlight Specific Contour Levels This example shows how to highlight contours at particular levels. Example: '--g' is a green dashed line. Set the x -axis tick values and associated labels by setting the XTickLabel and XTick properties of the axes object. Main Content. Define Z as a function of two variables, X and Y. And the yellow region corresponds to heights that are greater than 3. Use array operators instead of matrix operators for the best performance. The characters and symbols can appear in any order. LineSpec — Line style and color character vector string scalar. If you want interpolated shading instead, use the fsurf function and set its 'EdgeColor' option to 'none' followed by the command view 0, The properties listed here are only a subset. Each contour line starts with a column containing Z and N values:.
