[Jim Tonti]

After spending too much time trying to plot
radiation patterns the hard way, I tried
this, and all my problems were solved!
It's well thought out, documented, and it works!
Thank you, David.

[Catherine Johnson]

Very Useful! Thank you

[Steve Hobbs]

Easy to use, and great plots of radiation patterns. Thanx!

[Shad Holt]

this is sweet, after trying to plot radiation powers in polar-logrithmic form for hours, this file allowed me to do it in minutes. great help.
If you need to plat radiation patterns in dB, this is the way to do it.

[Keith Gooley]

Spent an hour or two trying to plot antenna radiation patterns without satisfaction. This function did it almost straight away. Thank you.

[Joe Derk]

Geat code! Infinitely better than MATLAB's base polar plot.

[Eric L.]

Thank you!! Excellent function!

[Pascal Everton]

Thanks for the great function! Now I can quickly and easily plot antenna radiation patterns!

[A B]

this 65 KB of code contain a trojan what doesn't help that much with antennas

[Marcelo Zeri]

I could not use it with subplot...

[mike miller]

thanks for the great job. it is realy help for polar plot.

one question, i compiled it with matlab 6.5 compiler, but can not run it. it generated the following error at runtime:

conversion to cell from char is impossible

any suggestion?

[Rob S]

Awesome! A vast improvement on the standard function.

[Isabelle Schmich]

very helpfull

[Oliver Tong]

It is excellent. Wonderful. But I seem to have a problem with plotting two plots together. When "Hold is on", there seems to be some error.

[Michael Bergandi]

Doesn't work in R14.

[Dan Boateng]

A try

[Julian Endres]

great work! How can I insert text into the plot using text() or something like that?

[Cloud Chu]

I could not use this with R being negative value.

[Vasikaran Prabaharan]

How to give input data to the function..

Can you give some example using this PP function..

[Marcus Loh]

Excellent help tools

[srinivas]

Can you please help me with this problem ? .... I am using Matlab 7.6 .....

I am getting error msg for a simple input data as shown below ......

Command:

pp([1 2],[3 4])

Error:

??? For colon operator with char operands, first and last operands
must be char.

Error in ==> pp>PlotTrace at 1262
        x =
        norm_r(PlotStartFlag(i):PlotBreakFlag(i)).*cos(theta(PlotStartFlag(i):PlotBreakFlag(i)));
        
Error in ==> pp at 287
    PlotTrace(ThetaPlot, RPlot, PlotProperties, Traces{i+1});

[Dr. Thomas Patzelt]

The reason for the problem above is that the author of Advanced Polar Plots did not concern that PlotBreakFlag might be empty. The present MATLAB versions (e.g. MATLAB Version 7.7.0.471 (R2008b) for Linux) seem to be more sensitive in detecting such mistakes. To avoid the problem I modified pp.m starting with line 1056:
...
if(InPlotFlag == 1)
    if isempty(PlotBreakFlag)
        PlotBreakFlag = [length(norm_r)];
    else
        PlotBreakFlag = [PlotBreakFlag length(norm_r)];
    end
end
...
Hope, this little workaround will help you!

[Justin Elstrott]

Hi,
  Has anyone had any luck with the fix suggested in the 02 Dec 2008 post?

[Daniel Armyr]

I added Patzelts fix to the original code and resubmitted it as http://www.mathworks.com/matlabcentral/fileexchange/22859

[Noelia Oses]

Hi all,
I have found this function when searching for how to make the a polar plot look like a compass from 0 to 360 deg clock wise and that the center to 0 axis is vertical pointing up. And this function has done exactly that for me.
However, it doesn't actually plot my data, which was being plotted by polar(theta,rho) just fine.

Does anybody know what's going on?
Thank you very much in advance,
Noelia

PS: the error message is:

??? For colon operator with char operands, first and last operands
must be char.

Error in ==> pp>PlotTrace at 1262
        x =
        norm_r(PlotStartFlag(i):PlotBreakFlag(i)).*cos(theta(PlotStartFlag(i):PlotBreakFlag(i)));
        
Error in ==> pp at 287
    PlotTrace(ThetaPlot, RPlot, PlotProperties, Traces{i+1});

Error in ==> PlotGaitData at 13
pp(theta,rho,'-or','ThetaDirection','cw','ThetaStartAngle',270,'CentreValue',0)

[Jeffrey Hall]

Is there anyway that someone could please send me a MATLAB code snippet showing pp.m in all of its glory?
 
I am evaluating multiple software packages for creating polar plots and am on a tight schedule.
 
Thanks.

[Noelia Oses]

Hi all,

I am using pp to plot polar plots and it's great!
However, even though I'm using style 'or' it still plots the lines linking the markers.
Does anyone know what to do so that it doesn't plot the lines?

Thank you very much!!
Noelia

[Faisal]

hi all,

i need demo for this script... can any 1 give it to me.. thx alot

[Huizi]

thank you very much, helpfully

[shruthy reddy]

can u plz help me in plotting (radiation patterns) polar plots with data 0- 50db in matlab
