Thanks for your feedback .
Your app explains the problem .
If we see the cumulative sales for 2013 its actually valid only till today .
But that chart line flattens and shows up as a horizontal line to the right side which we want to avoid .
Instead of flat line, we need to show another line which will do forecast for the rest of the year .
Any ideas how we can acheive that ?
