start_x    :  x-axis starting (progressbar starting[x-cordinate])
end_x      :  x-axis ending   (progressbar ending[x-cordinate])
y          :  Row no. where progressbar should be placed
symbol     :  Symbol to be displayed
style      :  0 for smooth progressbar
          1 for rough progressbar
dlytime    :  delay time (in milliseconds)
