Hello MK,
Not sure if the Graph would be able to handle more than 32 points.
Alternatively, you can try displaying your data in WebPage exposing via RestFul Webservice integrating open source librarby D3.js. Check out one of my post Bring Data to Life – Integrating D3.js in SAP via RESTful Web Service – Sneak Pick at d3.js (Part I) Let me know what you think about this?
