restrict number of levels and go back up without traversing to bottom first about d3treer HOT 13 CLOSED

This case with 6 levels is more or less what I'm trying to do

1 School District -> 20 Schools -> 3 Grades -> many Teachers -> 4 Classroom -> many Students

This is what it looks like when you have so many levels

That definitely helps. The problem is the labelling. In this case, I think the Mike Bostock version works much better. I'm trying to think through I can provide access to both while minimizing function and parameter bloat. I'll try to work through it and will enjoy your input.

@ignacio82 I spent a couple of hours implementing the example from Mike Bostock and the fork by Zan Armstrong. I think it will work much better with your example. Actually, thinking I might just go entirely with this version instead. Would you try it?

devtools::install_github("timelyportfolio/d3treeR@experiment/bostock")

Most everything on the R side should stay about the same.

Thanks.

@timelyportfolio great step in the right direction. The one big thing missing are the colors. This is what I get:

and this is what I get with googleVis:

Thanks!

Are you using the treemap package? d3treeR is designed to leverage the multitude of color options provided within that package. Do the colors on hover/mouseover appear more correct?

If you are using the treemap package, can you get a treemap that looks like the one with googleVis? Within treemap, there is a nifty function called itreemap that might be helpful. However, the aggregates seem to not fit the scale as I would expect. I'll pose the question over on the treemap repo.

I was able to get the colors like I want.Two more questions. Is it possible to add a legend for the color like in googleVis? is it possible to personalize what the tooltip is going to show?
Thanks

from d3treer.

Legends are very important, and I'm wondering how best to accomplish them, since treemap returns a range but not the full scale, so I'll need to recreate in d3.js. Guessing I'll try out the new d3-legend component from @susielu.

I do plan to have customizable tooltips also using one of the libraries such as d3-tip or kodama.

also, see mtennekes/treemap#18

Thanks for the great work!

Another option would be to rip the legend off from treemap with gridSVG. Almost thinking this will be the quickest way to get something up and going, but that will mean I will not have an immediate solution for JSON data.

from d3treer.

@ignacio82 see mtennekes/treemap#18 for a new fun.aggregate argument in treemap that should achieve the coloring you expect. Please let me know how it works.

thanks again for working through this with me.

from d3treer.

@timelyportfolio thanks! fun.aggregate solves the problem!

from d3treer.

I'll close this for now, since it is partially resolved. I think the other standalone issues will pick up the remaining pieces. Thanks so much @ignacio82.
