title: Vertical stacked bar chart using SharePoint List
body: <p>I have to create a stacked bar chart using the SharePoint complex list data using REST, JavaScript. The main problem here is i am not getting proper data sets.</p>
  
  <p>Let me clear my scenario here: Suppose i am having a SharePoint-2013 list with 6 columns. I need a bar char based on column-1(Project Type) on x-axis, stacked by column-2(Technology) via count of different technology on y-axis. I am having 7 project type &amp; 15 technology &amp; want to processed around 200 rows with combination of them.</p>
  
  <pre><code>Project Java Python SharePoint .Net
  A        3     5        12       1
  B        4     7        6        3
  C        0     9        1        0
  </code></pre>
  
  <p>I open with any Chat.js whether it is chart.js/google chart.js/highlight chat.js The only thing i need data to be dynamic means whenever user add more values to project column should added to x-axis automatically.</p>
  
  <p>I am very new to this. Can anyone please help me to get this. need code part also. Many thanks in advance.</p>
