title: plot bar and fill according to % correct
body: <p>I have n sensors. For every round 1 to N I am going to see how many sensors are alive and draw it as a bar or box. the height of the bar will be the number of sensors.</p>
  
  <p>Also</p>
  
  <p>From the n sensor x will be correct y different by 10 values and z wrong. Can we display that by % of the bar colored according to x y z (green blue red for example)? </p>
  
  <p>in addition if the mean value is correct i want the contour of the bar to be blue else to be red.</p>
