respected sir, how can i plot a raw data file with respect height vs time i want to show first rangebin and with respect to time and i want to plot i in one colourand q channel with different color i used one program but is not working well clear all; close all; clc; %%% file read clear all; close all; clc;

rf=fopen('09JL2008.r2','r')

%%% header read for be=1:5 header= struct('npar',fread(rf,1,'int16'),'nwds',fread(rf,1,'int16'),'nrgb',fread(rf,1,'int16'),'nfft',fread(rf,1,'int16'),'ncoh',fread(rf,1,'int16'),'nicoh',fread(rf,1,'int16'),'ipp',fread(rf,1,'int16'),'pwd',fread(rf,1,'int16'),'cflag',fread(rf,1,'int16'),'nwin',fread(rf,1,'int16'),'w1start',fread(rf,1,'int16'),'w1len',fread(rf,1,'int16'),'w2start',fread(rf,1,'int16'),'w2len',fread(rf,1,'int16'),'year',fread(rf,1,'int16'),'month',fread(rf,1,'int16'),'day',fread(rf,1,'int16'),'hour',fread(rf,1,'int16'),'min',fread(rf,1,'int16'),'sec',fread(rf,1,'int16'),'nbeam',fread(rf,1,'int16'),'beam',fread(rf,1,'int16'),'scan',fread(rf,1,'int16'),'attn',fread(rf,1,'int16'),'noise',fread(rf,1,'int16'),'nrej',fread(rf,1,'int16'),'pthld',fread(rf,1,'int16'),'txpower',fread(rf,1,'int16'),'windfn',fread(rf,1,'int16'),'nomit',fread(rf,1,'int16'),'dtype',fread(rf,1,'int16'),'ver',fread(rf,1,'int16'),'gwind',fread(rf,1,'float'),'gwdir',fread(rf,1,'float'),'temp',fread(rf,1,'float'),'humid',fread(rf,1,'float'),'comments',fread(rf,48,'char'));
