Nifty Chart Confusion

I opened www.nseindia.com and found that the intraday chart it was showing was erroneous.
It is showing that nifty opened at 6250. Can this be possible?
So can somebody manipulate Nifty in this way?

I have attached the screenshot of the page for your reference.

That was in the Pre open session. Anythings possible.
