Hello Nathan,
Zooming in or out can be achieved by modifying the RadGanttView PixelLength at runtime.
We have an example in our WPF Demos showing how to do that - you can download the examples from this link, once they are installed go to the GanttView First Look demo. There we use a RadSlider to modify the RadGanttView PixelLength and achieve zooming in/out the TimeRuler Part.
I hope this will help.

Is there an online version somewhere? I am unable to install the demos from that link on my computer. Specifically, it aborts after encountering an error install SQL Express 2008

Hi ,
We are not sure what could be the reason for the described issue and I would be grateful if you could share some information, so we can try and reproduce it: What is your Windows version, your SQL version, your .NET Framework version and what is the exact error message during the installation?
I suggest taking a look at the RadGanttView First Look demo for Silverlight. It is almost the same as the one for WPF and the zooming in/out is demonstrated using a RadSlider.

Hello Nathan,
I suppose the error is caused by the lack of SQL Server on your machine. In order to install the WPF demos you need to have Microsoft .NET Framework 4 Client Profile (x86 and x64) and SQL Server 2008 Express.
Could you please give it a try and let me know whether this resolves the issue.
