You can display the repository files of a component (directly in the component section of your project area).
See the component folder in the picture above: a show history from a component in that folder, as opposed to a component in a stream, would display the full history of that file, instead of the filtered one from a stream.
This is similar to the "Show all in history" mentioned by Scott.
See "RTC file/element revision history":
In the Eclipse client, you can right click over a file loaded into a workspace and select "
Team -> Show History
".
This shows you the history of that file in that workspace.
You can then click on the "
Show all in repository
" tool icon, to see the history of all versions of that file. (You can do the same thing to a file in a stream/workspace repository files view, with the "Show History" operation).
