title: Horizontal bar chart plotting issues using achartengine
body: <p>I am tying to make a horizontal bar chart. I have 24 labels in total on the left axis. There are few issues that I am facing with drawing bar chart:</p>
  
  <p>1) I am showing limited number of entries when the bar chart starts. User can scroll to see other entries. As you can see in image 1, a bar is appearing 'below' the Y axis. I am unable to figure out How can I keep all the bar on top of the Axis. </p>
  
  <p>2) Second issue is that the values(or bars) are shifted downward by one. There is no bar in front of "00 AM" label but there is an extra bar below the last entry of 11 AM as shown on second Image. How to shift the bars?</p>
  
  <p>3) Instead of having tars for each label, is their a way in which I can show the bars in between those labels?</p>
  
  <p>Following is that chart that I am getting:</p>
