How Can I Expand the Maximum Visible Time Frame of a Roadmap?

The Roadmap automatically adjusts to a maximum time range according to the Elements placed on it.

A new Roadmap starts with a two-month time frame around your creation date.

If you need to expand the horizon of a Roadmap without having any activities attached to that space yet, consider setting a Milestone far ahead or back in time. This makes quick editing easier as you can add Activities directly on the canvas in the creation mode.
