clustergrammer/src/zoom/resize_label_val_bars.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

var utils = require('../Utils_clust');

module.exports = function resize_label_val_bars(params){

  var zoom_info = params.zoom_info;

  // resize label bars if necessary
  if (utils.has(params.network_data.row_nodes[0], 'value')) {
    d3.selectAll(params.root+' .row_bars')
    .attr('width', function(d) {
      var inst_value = 0;
      inst_value = params.labels.bar_scale_row(Math.abs(d.value))/zoom_info.zoom_y;
      return inst_value;
    })
    .attr('x', function(d) {
      var inst_value = 0;
      inst_value = -params.labels.bar_scale_row(Math.abs(d.value))/zoom_info.zoom_y;
      return inst_value;
    });
  }

  if (utils.has(params.network_data.col_nodes[0], 'value')) {
    d3.selectAll(params.root+' .col_bars')
      .attr('width', function(d) {
        var inst_value = 0;
        if (d.value > 0){
          inst_value = params.labels.bar_scale_col(d.value)/zoom_info.zoom_x;
        }
        return inst_value;
      });
  }

};
