javascript - dc.js: Reducing rows in data table -


so have data.table object being outputed this:

gender  hair-color  pets  group1.totals   group2.totals   group3.totals   f       black      y       10               0                 0   f       black      y        0               7                 0   f       black      y        0               0                 8

how collapse this? 

  gender  hair-color  pets  group1.totals   group2.totals   group3.totals     f       black      y         10               7                 8

i have tried reducing dimensions doesn't seem work. code below:

ndx = crossfilter(data); datatable = dc.datatable('#data-table'); var tabledim = ndx.dimension(function(d) {     return d.gender + "/" + d.hair-color + "/" + d.pets;       });  datatable    .width(400)    .height(800)    .dimension(tabledim)    .group(function(d){      return "data counts";     }),    .columns([       function(d) {         return d.gender;        },       function(d) {         return d.hair-color;        },       function(d) {         return d.pets;       }       function(d) {         if (d.group == 1) return d.totals;           else return 0;       },       function(d) {         if (d.group == 2) return d.totals;           else return 0;       },       function(d) {         if (d.group == 3) return d.totals;           else return 0;

essentially know have reduce , group data can't find have in order achieve. great, thanks!

use following code;

var ndx=crossfilter(data); var dimension=ndx.dimension(function(d){return d.hair-color}); var databyhaircolor=dimension.group().reducecount();

i hope it'll solve problem. if want other filtering option use that. used hair color. let me know if still facing issues
