How can I reduce the redrawing of the canvas?

queryEachTime indicates that the collection of included nodes should be query each time. (cy.nodes("....")) Which is quite heavy. Not sure whether you need that. I guess you are looking more in the order of updateOn = 'render'.

if you are using the canvas approach, why do you need four canvases? Why not just render everything at once/

1. I set queryEachaTime=true because I found that when I delete a node, the custom layer does not automatically update, and the custom tag of the deleted node still exists.

2. My requirement is to add node values, attribute values, and various labels to the node. The use of multiple layers is to update the canvas more efficiently. For example, if the label changes, I only need to update the label layer.

Sorry, I noticed that when I upgraded the version, issue 1 has been fixed and I no longer need to set queryEachTime=true

canvas is pretty fast, so I don't know whether you are getting any benefits because you also have overhead such as clearing and aligning each layer
