how to optmize/speed up rendering on network #2556
Comments
Hi there! However, if you want to speed up things (and I think that is where the problem lies) ... if you zoom in and out while the graph is still rearranging itself (e.g. after dragging some nodes around), there is just a lot to do for your browser. An easy solution is to show the network once it's done with rearranging (So first show a loading bar and only display the network once everything is in place). It helped me a lot to speed up things. This can be done and I can point you into the right direction, however I don't know if you are happy with that solution of if you like the dynamic movement at the start up :) |
Hi @LLTommy, sure! please give me some pointers to implement that and see how it works |
No, the loading does not really take a lot of time. It saves computational power I think because you separate the two steps (1 physic calculation, 2 display and render the network).... if you don't separate it, your script in parallel calculates the physics (It's a force model, so every edge and node influences the others!) and display/animate the network. Anyway, check out this official vis example for a loading bar: http://visjs.org/examples/network/exampleApplications/loadingBar.html - if you have problems come back here, I might be able to help because I implemented my own loading spinner in my project. Cheers. |
thanks @LLTommy ! , I will check that, I hope it improve performance |

Hi, we are using vis js to render our graphs, fantastic library!
we are rendering graphs with a limit of 170 nodes, as you zoom the graph you get slow rendering when labels start to appear.
we are using edges with labels and physics configured with this settings:
is there some fine tuning you would recommend me in order to speed up the rendering ?
you can see a live example at: http://vadb.org/people/miguel-michelson-martinez/graph
let me know if you need more information
best
