For a list of properties, see Line Properties. If you want different behavior, you can manipulate rho prior to plotting. For example, you can set rho equal to max 0,rho or abs rho. Line style, marker, and color, specified as a string scalar or character vector containing symbols. The symbols can appear in any order. You do not need to specify all three characteristics line style, marker, and color.

Help Center Help Center. You can plot a polar equation in an app using the polaraxes and polarplot functions. In this example app, when an app user changes parameter values or component properties, the polar plot updates to reflect the changes. This example demonstrates these app building tasks:. Create different types of axes programmatically to display plots that uiaxes does not support. You can add specialized axes to an app programmatically.

A polar plot is created on a polar coordinate system which is a two-dimensional coordinate system that shows the distance of the point from the origin and its angle concerning the x-axis. We can use the polarplot function of Matlab to create a polar plot. The basic syntax of the polarplot function is below. If the two inputs are vectors, they should have equal lengths. If both inputs are matrices, they should have the same size, and in this case, each column of the first matrix will be plotted against each column of the second matrix. If one input is a vector and the other input is a matrix, then the length of the vector should be equal to the length of columns or rows present in the matrix, and each column of the matrix will be plotted against the vector. If a single input of the polarplot function is a matrix, the function will plot more than one line on the polar plot with different colors. In the above code, we used two vectors, and we can see in the output that the plot shows the angle and distance of points from the origin.

To change the limits of the theta-axis, use thetalim. For a custom color, specify an RGB triplet or a hexadecimal color code. Use ln to modify the polar plot after it is created. By default, the object does not display markers. You cannot specify different Name,Value pairs for each line using this syntax. A vartype subscript that selects variables of a specified type. The values are not case sensitive. If the inputs are matrices, then polarplot plots columns of rho versus columns of theta.

The compass function takes its inputs in Cartesian format , but outputs polar plots. This function creates arrows that go out from the origin of the axes in a polar coordinate system.

The symbols can appear in any order. Input Arguments collapse all theta — Angle values vector matrix. Convert the values in theta from degrees to radians. Therefore, the color codes " FF" , " ff" , " F80" , and " f80" are equivalent. Example: polarplot tbl,"theta",["rho1","rho2"] specifies the table variables named rho1 and rho2 for the radius values. Specifying a marker symbol adds markers at each data point or vertex. Other MathWorks country sites are not optimized for visits from your location. Add a legend.
