clustergrammer/src/reorder/update_reorder_buttons.js

This is a clustergram implemented in D3.js. I started from the example http://bost.ocks.org/mike/miserables/ and added the following features

module.exports = function update_reorder_buttons(tmp_config, params){
  _.each(['row','col'], function(inst_rc){

    var other_rc;
    if (inst_rc === 'row'){
      other_rc = 'col';
    } else {
      other_rc = 'row';
    }

    d3.selectAll(params.root+' .toggle_'+other_rc+'_order .btn')
      .filter(function(){
        return d3.select(this).attr('name') === tmp_config.inst_order[inst_rc];
      })
      .classed('active',true);

  });  
};
