Can't set x-axis label

Confirming that the aggregation has nothing to do with the inability to set the label. I made a basic view of comments per node. Setting node title as the x-axis label is not possible. Using highcharts library 2.1.9

I couldn't find anywhere in the module code where the label was actually being passed to the JS, so I figure that piece was just incomplete? dunno?

Anyway, I got my x-axis labels working by putting this chunk of code in views_highcharts_theme.inc around line 96

It's not thoroughly tested.

//Get which field we've set as our label from the options
$label_field = NULL;
$label_field = $vars['options']['x_axis']['dataset_label'];

if($label_field){
  
  //Return all labels based on the view
  $view_rows = $vars['view']->style_plugin->rendered_fields;
  
  $labels = array();
  foreach($view_rows as $key => $row){
  	$labels[] = $row[$label_field];
  }
  
  
  $highcharts_config->xAxis->categories = $labels;
}
