Coherent highlighting over the time correlated data charts
After upgrade to Drupal 7 it is required to add an extra feature - user should be able to
select/highlight vertical segment on the data charts and this selection should be saved when posted as issue so
any network expert will be able to see right away where is the problem. Also if user posts issue as link to the
network monitoring results then network expert should be able to highlight some problem area and user should be able to see this shared highlighting.
