d3.js - Inserting a line break in D3 force layout node labels -
so, playing force directed graph, , i've made .text on node changes on mouse on text data.
my code looks this:
script:
var data = {"nodes":[ {"name":"yho", "full_name":"yahoo", "type":1, "slug": "www.yahoo.com", "entity":"company", "img_hrefd":"", "img_hrefl":""}, {"name":"ggl", "full_name":"google", "type":2, "slug": "www.google.com", "entity":"company", "img_hrefd":"", "img_hrefl":""}, {"name":"bng", "full_name":"bing", "type":2, "slug": "www.bing.com", "entity":"company", "img_hrefd":"", "img_hrefl":""}, {"name":"ydx", "full_name":"yandex", "type":2, "slug": "www.yandex.com", "entity":"company", "img_hrefd":"", "img_hrefl":""}, {"name":"desc1", "type":4, "slug": "", "entity":"description"}, {"name":"desc2", "type":4, "slug": "", "entity":"description"}, {"name":"desc4", "type":4, "slug": "", "entity":"description"}, {"name":"ceo", "prefix":"mr.", "fst_name":"jim", "snd_name":"bean", "type":3, "slug": "", "entity":"employee"}, {"name":"att", "prefix":"ms.", "fst_name":"jenna", "snd_name":"jameson", "type":3, "slug": "", "entity":"employee"}, {"name":"cto", "prefix":"mr.", "fst_name":"lucky", "snd_name":"luke", "type":3, "slug": "", "entity":"employee"}, {"name":"cdo", "prefix":"ms.", "fst_name":"pamela", "snd_name":"anderson", "type":3, "slug": "", "entity":"employee"}, {"name":"ceo", "prefix":"mr.", "fst_name":"nacho", "snd_name":"vidal", "type":3, "slug": "", "entity":"employee"}, ], "links":[ {"source":0,"target":4,"value":1,"distance":5}, {"source":0,"target":5,"value":1,"distance":5}, {"source":0,"target":6,"value":1,"distance":5}, {"source":1,"target":4,"value":1,"distance":5}, {"source":2,"target":5,"value":1,"distance":5}, {"source":3,"target":6,"value":1,"distance":5}, {"source":7,"target":3,"value":10,"distance":6}, {"source":8,"target":3,"value":10,"distance":6}, {"source":9,"target":1,"value":10,"distance":6}, {"source":10,"target":1,"value":10,"distance":6}, {"source":11,"target":2,"value":10,"distance":6}, ] } var w = 560, h = 500, radius = d3.scale.log().domain([0, 312000]).range(["10", "50"]);

}); }); //}); you can see working example in jsfiddle: http://jsfiddle.net/dzorz/6phkn/
the part of code bothers me mouseover:
else if(d.entity == "employee"){ d3.select(this).select('text') .transition() .duration(300) .text(function(d){return d.prefix + ' ' + d.fst_name + ' ' + d.snd_name}) .style("font-size","8px") } i wanna add line break between d.fst_name , d.snd_name , tried '\n' , '<\br>' , not doing wanted get...
which way in d3 add line break on text?
you can edit linked jsfiddle above...
any suggestion welcome
here answer without using html inside svg because reason wont work force stuff.
else if(d.entity == "employee"){ var asdf = d3.select(this); asdf.select('text').remove(); asdf.append("text") .text(function(d){return d.prefix + ' ' + d.fst_name }) .attr("class","nodetext") .attr("dx", 0) .attr("dy", ".35em") .style("font-size","5px") .attr("text-anchor", "middle") .style("fill", "white") .transition() .duration(300) .style("font-size","12px"); asdf.append("text").text(function(d){return d.snd_name }) .attr("class","nodetext") .attr("transform","translate(0, 12)") .attr("dx", 0) .attr("dy", ".35em") .style("font-size","5px") .attr("text-anchor", "middle") .style("fill", "white") .transition() .duration(300) .style("font-size","12px"); } jsfiddle example: http://jsfiddle.net/cuckovic/fwkt5/
