MATLAB has a wide variety of plotting commands enabling you to also create polar plots, histograms and many more. *cos(2*t),'--r') See Also. Executing the command Executing the command view([90 -90]) You can also plot other types of polar data. *cos(tvalue); polar(tvalue,r) Output: In the above example, this will plot the line in the respective polar coordinates. Polar properties control the appearance and behavior of the polar plot function object. To create polar coordinate plots, MATLAB offers the polar method, which is unfortunately quite limited in functionality. Use these plots when interactive data visualization or measurement is required. For all circuit objects except those that contain data from a data file, you must use the analyze method to perform a frequency domain analysis before calling polar.. Use the function polarpattern (Antenna Toolbox), or the MATLAB ® function polarplot to plot parameters that are not part of a rfckt or rfbudget object, but are specified as vector data. Use the default line style for the first line. Gain a better understanding of Root Locus Plots using Matlab - Duration: 19:11. Examples. Add a legend with a description for each chart. Would anyone know how to adjust (rotate) the polar plot function such that the vertical axis starts at 0 degrees - as opposed to 90? for n=1:5. polarplot (theta,y (n,:)); leg = strcat (leg,''',num2str (n),'''); polar(theta,rho,LineSpec) LineSpec specifies the line type, plot symbol, and color for the lines drawn in the polar plot. The functions that we used in this video are polarplot, meshgrid, surf. × MATLAB Command. Customize Polar Axes. Create a figure with a line chart and a scatter chart. an array. Field Description; Peer: Chart object associated with the clicked legend item. Generate a legend label for this plot. Adding legend in a plot genereted by a loop. Examples. a cell array. You can modify certain aspects of polar axes in order to make the chart more readable. The values can be an array of angles or array of magnitude. The variables theta and rho must be identically sized vectors. Then, ensure pax is the current axes before calling the polarplot function. Just define a legend that increments each loop and then it adds it to the polarplot.
