clustergrammer/src/enter/ds_enter_exit_update.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 reset_size_after_update = require('../reset_size/reset_size_after_update');
var make_col_label_container = require('../labels/make_col_label_container');
var show_visible_area = require('../zoom/show_visible_area');
var resize_containers = require('../reset_size/resize_containers');

module.exports = function ds_enter_exit_update(cgm){

  // console.log('======== ds_enter_exit_update ===============');

  // remove row labels, remove non-downsampled rows, and add downsampled rows
  d3.selectAll(cgm.params.root+' .row_cat_group')
    .remove();
  d3.selectAll(cgm.params.root+' .row_label_group')
    .remove();
  d3.selectAll(cgm.params.root+' .row')
    .remove();

  // no need to re-calculate the downsampled layers
  // calc_downsampled_levels(params);
  var zooming_stopped = true;
  var zooming_out = true;
  var make_all_rows = true;

  // show_visible_area is also run with two_translate_zoom, but at that point
  // the parameters were not updated and two_translate_zoom if only run
  // if needed to reset zoom
  show_visible_area(cgm, zooming_stopped, zooming_out, make_all_rows);

  make_col_label_container(cgm);

  var col_nodes = cgm.params.network_data.col_nodes;

  // remove column labels
  d3.selectAll(cgm.params.root+' .col_label_group')
    .data(col_nodes, function(d){return d.name;})
    .exit()
    .style('opacity',0)
    .remove();

  d3.selectAll(cgm.params.root+' .col_label_text')
    .data(col_nodes, function(d){return d.name;})
    .exit()
    .style('opacity',0)
    .remove();

  d3.selectAll(cgm.params.root+' .col_cat_group')
    .data(col_nodes, function(d){return d.name;})
    .exit()
    .style('opacity',0)
    .remove();

  d3.selectAll(cgm.params.root+' .col_dendro_group')
    .data(col_nodes, function(d){return d.name;})
    .exit()
    .style('opacity',0)
    .remove();

  // necessary for repositioning clust, col and col-cat containers
  resize_containers(cgm.params);

  // seeing if this fixes resizing issue
  var delays = {};
  delays.enter = 0;
  delays.update = 0;
  delays.run_transition = false;
  var duration = 0;
  reset_size_after_update(cgm, duration, delays);
