Several rightmost points are truncated in chart

[ilshiyi]

http://jsfiddle.net/ilshiyi/MBhnT/1/
In the above link, the array has 3600 points. So the rightmost point should be 3599. But actually only 3594 is displayed. When I use scaler to enlarge the rightmost part, the rightmost point is 3593.
This issue also exists in the demo http://www.humblesoftware.com/envision/demos/finance

I append some null values to the end of data to temporary solve this issue

I had the same problem with my project. I tracked down the error with the help of another issue on this project.
See my comment for a good solution to this, I will submit a pull request when I am able.
