clustergrammer/src/update/update_cats.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 make_row_cat = require('../dendrogram/make_row_cat');
var calc_viz_params = require('../params/calc_viz_params');
var resize_viz = require('../reset_size/resize_viz');
var modify_row_node_cats = require('./modify_row_node_cats');

module.exports = function update_cats(cgm, cat_data){

  // Only accessible from the cgm API, cat_data is provided by externally
  ///////////////////////////////////////////////////////////////////////////

  if (cgm.params.cat_update_callback != null){
    cgm.params.cat_update_callback(this);
  }

  // do not change column category info
  var col_cat_colors = cgm.params.viz.cat_colors.col;

  modify_row_node_cats(cat_data, cgm.params.network_data.row_nodes, true);
  // modify the current inst copy of nodes
  modify_row_node_cats(cat_data, cgm.params.inst_nodes.row_nodes, true);

  // recalculate the visualization parameters using the updated network_data
  cgm.params = calc_viz_params(cgm.params, false);

  make_row_cat(cgm, true);
  resize_viz(cgm);

  cgm.params.new_row_cats = cat_data;

  cgm.params.viz.cat_colors.col = col_cat_colors;

};
