What do you mean data lost? Could you elaborate?
The canvas should be preserved, even if you do not explicitly save it. If it does not, it is either a bug or you saved it in the scene, in which case it will not attempt to keep it open.
I just tested in 2019.3 that it works, what Unity version are you using?
from node_editor_framework.
I edit canvas in Init scene, save it as an asset file, close NodeEditor,I observe the data in inspector,it's right, but switch to other sence. The saved asset file is empty data, Unity2018.4.24f1 install NodeEditor and UndoPro with unitypackage
from node_editor_framework.
So to clarify:
- You did not save the canvas in the scene explicitly, you just had the scene open while editing, before saving it as an asset
- The data you observe in the inspector is the node canvas UI with title, nodes, etc, after you select the saved asset file (?)
- Upon changing scene, clicking on that same asset file again yields what? Node Canvas UI with no nodes?
- Now after reopening the window what does it say when you try to open that saved asset file?
When switching scene it will of course unselect the canvas you had selected, resulting in a blank inspector window, so make sure you still have the canvas selected, just in case.

Now the replication step is, at run time, I load the asset for parsing, then switch scenes, and the saved asset is lost,
Here is a GIF that emulates the scene switch at run time
