How do I polar plot an array from an imported file in matlab?

Hi all, I have a file containing some data, with multiple rows (Time dependent) and 4 fixed columns. I want to polar plot this data such that:

0 - 90 degrees represents column 1

91 - 180 degrees represents column 2

181 - 270 degrees represents column 3

271 - 360 degrees represents column 4

Should any of the values in the column exceed the value of 1000 it will be shown on a given radius marker on the plot

Would it be possible to actually show my data in this manner?

Here is my code:

A = csvread('Polarplottest.txt');
B = A>1000
C = all(B, 2);
C = all(B(:,[1,2,3]), 2);% PowerGrip
D = all(B(:,[1,2,4]), 2);%PowerGrip
F = all(B(:,[1,3]), 2);   % PrecisionGrip(Upper)
G = all(B(:,[2,4]), 2); %PrecisionGrip(Lower)
E = cell( size(C) ); % Make a cell array to hold strings, same size as C
E(:) = {'none'};     % Fill all rows with "none" to start. Could use repmat() to create E...
E(C | D) = {'PowerGrip'}; 
E( F & not(C | D | G) ) = {'PrecisionGrip(Upper)'};
E( G & not(C | D | F)) = {'PrecisionGrip(Lower)'};
T = array2table(A)
T.Desc = E

Would this be in line with what you're trying to achieve?

% Example data
% 4 columns of random of values between 650 and 1050
t = array2table(randi([600,1050],50,4)); 
t.Properties.VariableNames = {'colA','colB','colC','colD'}

% get all data and store as vector:
allData   = t{:,:};
allData   = reshape(allData,[],1)

% create the angle vector:
angleVect = linspace(0,2*pi,length(allData))

%plot the polar plot
figure
polarplot(angleVect, allData,'--.r')
% add markers for 'allData' > 1000
hold on
polarscatter(...
    angleVect(allData>1000),...
    allData(allData >1000),...
    'ko')

This worked perfectly for me. Thank you so much!
