Hi Vishwas,
          The content of data in the file is a simple integer ranging from 1 to 100. These numbers are generated by running a shell script:
    //Starting tag for shell script
        for(( i=1;i<=300; i++))
	     do
		shuf -i 1-100 -n 1
		sleep 1
	     done
    //Ending tag for shell script
In the Javascript code

  I am calling an update script function after an interval of 2 seconds. On increasing the interval time to 4 or 5 seconds, the number of missing points in the graph reduces.
