I recently use TIBCO Spotfire running with desktop version 6.5.
For data display, I would like to know whether it is possible to display external information (web page or web-enabled content) in a tab with analysed data. For example, an analysis tab can include map charts, raw data table, Google search page, blog, articles, and videos from web all together in a tab.
I do not know how to add or embed those web-enabled content/windows with some analysed data already, and to display them together within a single tab.
The reason I do this is because I wish those external information can be put as a reference by the side of analysed data. The external information is not necessarily interacted with the analysed data, and just for referencing purpose.
Your best bet is probably to get in contact with your Spotfire sales rep and ask about if and how you could get access to JSViz -- this is a framework/visualization component provided by their Professional Services to run HTML and Javascript inside Spotfire Desktop.
The heavy weight alternative would be write something like this yourself using the C# extension APIs (i.e., a custom visualization component that more or less just contains an embedded Web Browser).
A light weight alternative might be to just have Spotfire link to the Web page you want and have it opened in a regular browser that then has its own window (rather than a tab within Spotfire Desktop). You can do such links in many visualization components (e.g., in tables you can set a column to be a link) or you can use a TextArea with a script button that has a small IronPython script attached that starts the Web Browser.
The Spotfire Blog also has a couple of more tips of what you can do with the TextArea to display external information there.
Finally, consider if deploying your DXP to WebPlayer and doing a full-scale JavaScript Mash-Up there could be an alternative.
