We can see that hold on/all does not work as expected for polar plots (see subplot, top right). Your problem may be related to that. comp.soft-sys.matlab . I have project in matlab.That is broadside array pattern.Below code, i achieved array factor as a magnitude, but when i converted array factor to dB graph is changed and corrupted. Discussion: Polar plot with dB scale (too old to reply) Jennifer Cohen 2007-08-06 13:10:28 UTC. polarpattern class plots antenna or array radiation patterns in interactive polar format. Any ideas how I can convert the rho axis to a ... polar plot into semi log polar plot, just as people can Learn more about polar diagram, cartesian diagram, log polar diagram, array antenna MATLAB Permalink. Right-click the Polar Measurement window to change the properties, zoom in, or add more data to the plot. However, because the way you construct your function, when MATLAB evaluates it, it notices that it is inf*0, so it gives you an NaN (Think for example the case of sin(x)/x). I have one questin abouth broadside array and polar pattern as dB. this is a basic polar plot tool in dB , you can change the range which can be very helpful for analyze the nature of your pattern. They are also helpful in changing the axes in the polar plots. I have project in matlab.That is broadside array pattern.Below code, i achieved array factor as a magnitude, but when i converted array factor to dB graph is changed and corrupted. Now, I would like to extract the data of these plots to matrices, so i can import the data in excel. Plotting antenna radiation patterns: polar.m from MATLAB: >> help polar POLAR Polar coordinate plot. Regards . You can also plot other types of polar data. Polar properties control the appearance and behavior of the polar plot function object. I used subplot to illustrate the different example. In Matlab, polar plots … Therefore, you need to identify those cases yourself before you plot so it does not try to plot NaN, which is a gap. I have one questin abouth broadside array and polar pattern as dB. POLAR(THETA,RHO,S) uses the linestyle specified in string S. See PLOT for a … Joined Mar 15, 2009 Messages 37 Helped 4 Reputation 8 Reaction score 2 Trophy points 1,288 Location Egypt Activity points 1,494 how to plot in matlab matlab polar db Hi mns, I've never tried 3D polar plots in matlab but seems an interesting exercise. I recieved a series of polar plots [Example_n.fig, with n = (1000:1:1250)] for 36 headings. Here is a test code: %----- % Linear Arrays of Isotropic Elements const=1; lambda=1; k=2*pi/lambda; theta=linspace(0,2*pi,200); d=1/1*lambda; … Apr 16, 2009 #12 M. mostafa ahmed Member level 1. RGB Triplet Hexadecimal Color Code Use these plots when interactive data visualization or measurement is required. The remaining values are negative and 0 should be at the outermost circle in a polar plot. If I use regular polar() function negative values are put on the opposite side of where it should be. POLAR(THETA, RHO) makes a plot using polar coordinates of the angle THETA, in radians, versus the radius RHO. Thus, the polar plot looks like it is flipped. Here is a way to plot several polar graphs in a single figure. Using MATLAB I would like to plot antenna radiation pattern whose maximum value is set to 0. One workaround is to plot the biggest polar graph first and then plot the smallest one. Working of Polar Plot in Matlab. The polar plot is the type of plot which is generally used to create different types of plots like line plot, scatter plot in their respective polar coordinates. I am trying to plot radiation patterns for antennas on a polar plot. I'll try and let you know. Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots. So I used the following code, which does open the figure and work for simple x,y - plots, but doesn't extract the data from the polar plots.
