## Matlab contour map example

The properties listed here are only a subset. Add a colorbar. The last color corresponds to Z -values that are greater than the highest level in the plot. The data is arranged sequentially in n sets of columns for n contour lines:. A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol followed by three or six hexadecimal digits, which can range from 0 to F. Then plot 20 contours of Z. XLim 2 ; ax. Assign the function contour object to a variable. For example, if you omit the line style and specify the color, then the plot shows solid lines using the specified color. LineSpec — Line style and color character vector string scalar.

This MATLAB function creates a contour plot containing the isolines of matrix Z, example. contour(___, levels) specifies the contour lines to display as the last.

## contour (MATLAB Functions)

This example shows how to label each contour line with its associated value. You can create a contour plot with emphasis on selected contour lines by. fcontour(___, LineSpec) sets the line style and color for the contour lines. For example, '-r' specifies red lines. Use this option after any of the previous input.

The ZData property of the Contour object stores the z -coordinates. Then display contours at 10 levels of Z.

## Filled 2D contour plot MATLAB contourf

Output Arguments collapse all M — Contour matrix matrix. To use a different color for each contour line, specify 'flat'. The white region corresponds to the heights less than 2.

The dimension that varies must be the opposite of the dimension that varies in X.

### Plot contours MATLAB fcontour

MATLAB Function Reference A contour plot displays isolines of matrix Z. Label the contour lines using clabel. Contour Plots section for more examples. A filled contour plot displays isolines calculated from matrix Z and fills the areas The number of contour lines and the values of the contour lines are chosen a regularly spaced contour grid, then transforms the data to X or Y.

## contourf (MATLAB Functions)

Contour line labels, specified as one of these values: 'off' — Do not label the contour lines. Number of evaluation points per direction, specified as a number.

In this case, call the peaks function to create XYand Z.

When X is a matrix, the values must be strictly increasing or decreasing along one dimension and remain constant along the other dimension.

The top number is the contour level, and the bottom number is the number of vertices.
Define Z as a function of two variables, X and Y. The default is You can specify several name and value pair arguments in any order as Name1,Value1, Dashed Contour Lines. |

Alternatively, you can specify some common colors by name.
