A DataPoint slide is always shown by default. In some situations you might like to skip a page when there's no data returned from the underlying data connections.

For example within a company's product overview presentation, you might like to skip the discount page when there are no discount products identified by your database.

Check the Hide this slide when there is no information from the data connection(s) box to hide the page. An unchecked box indicates that the slide is always shown.

All DataPoint enabled shapes are linked to a text file, a database or a Microsoft Excel document. Whenever the content of the data source is modified, it will be visible in your running presentation within seconds, depending on your connection's data refresh rate. Other links are possible to create outside DataPoint. For example you can insert a Microsoft Excel graph into your slide. This object is not directly supported by DataPoint (as DataPoint is limited to the content of an Excel cell itself), DataPoint is able to detect a modification on a graph and able to update it during your presentation.
To insert a living Microsoft Excel graph:

• Create your graph in Microsoft Excel. Select this graph and choose Copy from the Edit menu.
• In your Microsoft PowerPoint presentation choose Paste special from the Edit menu.
• Choose Paste link on your Paste special form and close the form.
• In the DataPoint menu choose Slide properties.
• Mark Refresh linked objects automatically when the source file is changed.

If you now start the presentation and the source (this is the Microsoft Excel document) is modified on another computer, even over the network, your presentation will detect it and refresh the graph in your presentation automatically.
