如何在页面刷新后禁用更改GoJS图表？

Question

My question will be simple. I'm new in GoJS diagrams building. And I have some static GoJS diagram in my web app page. But after I refresh page, diagram changes it's form. It still consists of the same blocks I have before refreshing but it only changes the form.

How could I disable it? I need the same form of diagram after refreshing.

Answer 1

Are you using ForceDirectedLayout ? I believe that is the only standard Layout with nondeterministic behavior, due to its usage of Math.random .

If so, set http://gojs.net/latest/api/symbols/ForceDirectedLayout.html#randomNumberGenerator to null.

The general alternative is to save locations for all of the nodes and use a Binding on Node.location .
