Prism Release 2

Miss as of now of now when user start drag and drop on the canvas so each new chart have more z-index then the previous charts on the canvas with this the new chart showing at the front of the previous one but we do have the option on chart's context menu which is "send to back" or "bring to front" with this user will able to handled the chart's positions. So if it is ok or not so let us know we can implement it accordingly.
