Question about months in the time line

[Žygimantas Jasiūnas]

I have a question about months in the time line, how can I set to see for example 3 or 2 months and so on? Could not find an answer.

To see more time before first and after last task you need to move Expand knob in the header.
You can also set in options something like:

/* ... */
scope:{
  before: 31, // for 31 days before first task
  after:31 // for 31 days after last task
}
/* ... */
