title: Multiple y-axis values against one single x-axis point
body: <p>I have implemented AMCharts JS library in one of my web apps and am having an issue. Right now i need to add multiple y-axis values to one single x-axis point (which is actually a date). I have  5 values 5,1,5,4,1,3 which contain same x-axis point (same date) but when i observe the graph sometimes 4 is missing while sometimes 5 as shown in the image. Am i really doing something wrong? This is the form of data </p>
  
  <pre><code>{date: "2016-03-29", value: 5}
  {date: "2016-03-29", value: 1}
  {date: "2016-03-29", value: 5}
  {date: "2016-03-29", value: 4}
  {date: "2016-03-29", value: 1}
  {date: "2016-03-29", value: 3}
  {date: "2016-10-20", value: 0}
  {date: "2016-10-20", value: 0}
  {date: "2016-10-20", value: 0}
  </code></pre>
