Hi Aashish,
Did you mean that the page will be always opened as editing mode, which contains the "Chart" web part ?
Did you customize this page ? Did this only happen to one user?
Please check whether there are some custom scripts executed on the page automatically? e.g. like result of executing CoreInvoke('PageActionClick',this);
Please remove and re-add the Chart web part from the page and check again, even create a new page.
Thanks
