Add titles, axis labels, informative text, and other graph annotations. Add a title, label the axes, or add annotations to a graph to help convey important information. You can create a legend to label plotted data series or add descriptive text next to data points. Also, you can create annotations such as rectangles ...You can define the excluded points as variables before supplying them as inputs to the fit function. The following steps recreate the fits in the previous example and allow you to plot the excluded points as well as the data and the fit. Load data and define a custom equation and some start points.polarplot(theta,rho) plots a line in polar coordinates, with theta indicating the angle in radians and rho indicating the radius value for each point.The inputs must be vectors of equal length or matrices of equal size. If the inputs are matrices, then polarplot plots columns of rho versus columns of theta.text (x,y,txt) adds a text description to one or more data points in the current axes using the text specified by txt. To add text to one point, specify x and y as scalars. To add text to multiple points, specify x and y as vectors with equal length. text (x,y,z,txt) positions the text in 3-D coordinates. example.Z = peaks (n) returns the peaks function evaluated over an n -by- n grid. If you specify n as a vector of length k, MATLAB ® evaluates the function over a k-by-k grid. example. Z = peaks (Xm,Ym) returns the peaks function evaluated at the points specified by Xm and Ym. The sizes of Xm and Ym must be the same or be compatible.Create a 2-D line plot and specify the line style, line color, and marker type.
