issues with big data sets about vue.d3.tree HOT 9 CLOSED

1. Understood, I played around with another type of zoom where the geometry were re-calculated some time ago. This waht we need here. There maybe have a commit somewhere in the history of this repo with such a code.
2. Ok
3. Thanks.

4. This is a good sugestion I will provide

from vue.d3.tree.

Any update on this?

@G3z version 4.1.0 introduces min and max zoom props as well as a "rescaling" zoom.
This correct problem 1 and 4 that you mentioned.

Hello @G3z , thanks for your feedback and suggestion

1. For the overlap mention, did you try the zoomable props and if so why was it not satisfactory?
2. This is an interesting suggestion, I like the open property more than a max number of nodes since it will be hard to decide which nodes to show. It will be a good idea also to make this open prop reactive.
3. Could you share your data as a JSON so I can play around with your data?

1. the problem with zooming is that everything just gets bigger or smaller proportionally (dots lines and text should stay the same size only move further apart), so you'll see the above graph bigger. negative margine works better (because drawing size gets bigger than svg size)
2. 👍
3. I'll clean the personal data and share it with you to do some tests asap
4. after tinkering with your lib i noticed min/max zooming is hard coded, using a prop would be better, don't you think ?

data.json.zip
this is a json of 9239 nested accounts
and this is the unzoomed result in a 1108x900 svg:

how can i help ?

I think i've found a simple trick to avoid overlapping:
currently you are setting the canvas size with cluster_size but it is possible to specify the node size

...
this.layout.size(this.internaldata.tree, size, this.margin, this.maxTextLenght)
.nodeSize([15, 200]); // add this = height:15, width:200px
...

@G3z could you detail better your proposal, or create a PR?
Thanks

I'm going by memory:

I propose to add a nodeSize property to tree that accepts an array in the form of [width,height] so that it's possible to set a size that prevent overlapping

In the code around here https://github.com/David-Desmaisons/Vue.D3.tree/blob/master/src/Tree.vue#L146
in resize() and completeRedraw()

...
this.internaldata.svg
              .attr('width', size.width)
              .attr('height', size.height)
this.layout.size(this.internaldata.tree, size, this.margin, this.maxTextLenght)
...

you are letting D3 figuring out node dimensions but it's possible to set the single node dimensions and this helps D3 prevent overlapping

...
this.internaldata.svg
              .attr('width', size.width)
              .attr('height', size.height)
this.layout.size(this.internaldata.tree, size, this.margin, this.maxTextLenght)
              .nodeSize([15, 200]) // this should come from props
...
