We can also change the line width similarly by setting any positive value to it. In the above plot, we have set the line color property as green so, the contour lines are displayed in green color. Please find the below example which explains the above properties: Example #2

They can be set to any positive value,0.5 is the default value. We can also customize the line width of the contour lines with the help of ‘LineWidth’ property in Matlab. They can be ‘- ‘for dashed line,’: ‘dotted line,’- ‘for a solid line,’-.’ for dash-dotted line and the solid line being the default line style. We can also change the shape of the contour lines with the help of ‘LineStyle’ property. Each color has its own predefined unique RGB value and the value defines the intensity of each color. Line color can be changed to red, green, blue, cyan, magenta, black, white, none with the help of ‘LineColor’ property in Matlab. We can also change the properties of the line by specifying its color, style, and width of the line.If we set the property to OFF, then there will be no filling of colors between the contour lines and this is considered as the default property when we use contour3 or contour function to plot the graph. If we want to fill any color between the contour lines in the plot, then we have to set the property to ON and it is considered as the default property when we use contourf function to plot the graph. It can be set to ON or OFF depending on the requirements. If we want to fill the spaces that are present in between the contour lines, then we can use the Fill property in Matlab.Please find the below properties that are used: There are various properties of contour lines that are used in customizing the contour lines with the various values. In the above plot, you can see the contour lines which are plotted against the input arguments that we have given. Please find the below example to see the commands used in displaying contour lines: Example #1 Meshgrid property in Matlab is used to create a matrix defined in the values of a and b coordinates. The property that is used to store coordinates in the x plane is XData and the property that is used to store b coordinates in the Y plane is YData. a and b coordinates defined can be a matrix or a vector but they should have the same size as given in X matrix. The data types that are supported by the matrix are double, single, int8, int32, int16, uint8, uint16, uint32, etc. X defined in the first syntax should be matrix and it should have at least two rows and columns with the defined values in them. contour(_, Name of the property, Value of the defined property): This syntax is used to set the name-value pair which is generally used to customize the contour lines by defining it in the argument with the property name and its required value.contour(_, Line Style Property): This syntax can be used to change the properties of the line which includes line color and size of the line which can be customized by giving the values.contour(_, levels of the contour lines): Levels of the contour lines can be set by deciding the height of the contour lines to display them at a particular height, which can be defined by any value.contour (a, b, X): This is used to define all the coordinates of a and b for the respective values in X.The row and column values of X are the respective coordinates which are used in the plane. contour(X): This is used to draw a contour plot where X contains the values of the height which are defined in the two dimensional(x-y) plane.They have different syntaxes which are used in Matlab like: Hadoop, Data Science, Statistics & others
