title: Bar Chart (Google Charts) with Vertical or Point Marker
body: <p>I am starting to work in visualizations and I am using Google Chart, I am trying to do a Bar Chart</p>
  
  <p><a href="https://developers.google.com/chart/interactive/docs/gallery/barchart" rel="nofollow">https://developers.google.com/chart/interactive/docs/gallery/barchart</a></p>
  
  <p>In which I could set a marker in a horizontal bar as a vertical line preferably or maybe a circle point to point out any value of my interest. Another option that could provide a way of marking a specific point in the bar chart would probably alright aswell.</p>
  
  <p>So any of you does know a way of doing this kind of Bar Chart with a Marker?</p>
  
  <p>Edited: The graph should look similar to this one:</p>
  
  <p><a href="http://chart.apis.google.com/chart?chs=100x40&amp;cht=bhs&amp;chco=000000&amp;chd=t:65&amp;chbh=15&amp;chm=r,ff0000,0,0.49,0.51,1" rel="nofollow">http://chart.apis.google.com/chart?chs=100x40&amp;cht=bhs&amp;chco=000000&amp;chd=t:65&amp;chbh=15&amp;chm=r,ff0000,0,0.49,0.51,1</a></p>
  
  <p>However not as an image but being able to interact with the object as it can be done using Bar Chart visualization.</p>
  
  <p>Thanks a lot,</p>
