Polar plots When information is given in polar coordinates, the command createLabels(p,format,array) adds I'd like to plot parameter values as a function of inclination (0-90deg) and azimuth (0-360deg) with the 'polar' function. As you are using polarplot instead of polarpatter, you can directly use "legend" to that, like a normal plot. I'm a fairly new user to MATLAB2016b, and am struggling a bit with 2D polar plots. I would do something like this: leg=''; figure. The values can be an array of angles or array of magnitude. az = [0:359]'; a1 = abs (cosd (az).^5); a2 = abs (cosd (az - 30).^5); a3 = abs (cosd (az - 60).^5); a4 = abs (cosd (az - 90).^5); P = polarpattern ( [a1,a2,a3,a4], 'Style', 'filled' ); createLabels (P, 'az = %d#deg' ,0:30:90) Hybrid Beamforming for Massive MIMO Phased Array Systems. Use the default line style for the first line. Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB ® uses in many types of plots. Compass Labels on Polar Axes .

You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. Just define a legend that increments each loop and then it adds it to the polarplot. >> theta = linspace(0,2*pi,1000); n = 1:5; y = zeros(length(n),1000); for i = 1:length(n) y(i,:) = sin(n(i)*theta); end polarplot(theta,y); This is my program. Reload the page to see its updated state. Create a figure with a line chart and a scatter chart. Specify the legend labels as inputs to the legend function. Open Live Script. Contour plot of polar coordinates. for n=1:5. polarplot (theta,y (n,:)); leg = strcat (leg,''',num2str (n),'''); Values to apply to format, specified as an array. creates a polar plot with 0 degrees on the left and increasing angles in the counterclockwise direction. Just define a legend that increments each loop and then it adds it to the polarplot. Would anyone know how to adjust (rotate) the polar plot function such that the vertical axis starts at 0 degrees - as opposed to 90? Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB ® uses in many types of plots. MATLAB: 2D polar plot axes & colour legend. To create polar coordinate plots, MATLAB offers the polar method, which is unfortunately quite limited in functionality. Values to apply to format , specified as This table describes the fields in the event data structure. Do you want to open this version instead? You clicked a link that corresponds to this MATLAB command: Run the … the specified format label to each array of *cos(tvalue); polar(tvalue,r) Output: In the above example, this will plot the line in the respective polar coordinates. For more information on legend label format see, legend. If you specify this property using a function handle, then MATLAB passes the Legend object and an event data structure as the first and second input arguments to the function. Details and Options The angle is measured in radians, counterclockwise from the positive axis. You can also plot other types of polar data. A few examples will be discussed. Executing the command Executing the command view([90 -90]) Examples. I.e. Download Python source code: polar_legend.py Download Jupyter notebook: polar_legend.ipynb Keywords: matplotlib code example, codex, python plot, … Create a polar plot of cosine powers rotated in 30° increments.
