code in matlab

polar(data(:,1), data(:,2), 'k-');  

which gives

you see first point (0) connected 2nd point (135). points connected in order 0 15, 15 30, ..., 150 165, , 165 0 possibly.

how can draw polar plot points connected order in column 1?

polar expects first input in radians, not in degrees. so, use

polar(data(:,1)*pi/180, data(:,2), 'k-'); 

with example values, gives

to connect last point first, repeat first point @ end:

polar(data([1:end 1],1)*pi/180, data([1:end 1],2), 'k-');
