Non-continuous time axis demo

Here's an example showing how you can customize the TimeAxis class. In the top sample, a special header-renderer is used that outputs only start/end for each header cell. A few business rules have also been applied: events can not span multiple days, and they cannot be moved between days either once they have been created. In the bottom sample you can see how to apply filters to the time axis, similar to what you can do with a regular Ext JS data Store.
