    Default Answered: Chart Interactions through controller

    Hey,

    I am working on a touch charts application with a MVC structure.
    I read about how the charts use interactions to respond to user events, one of these interactions is the 'itemInfo'. The example of it looks like this:
    Code:
    interactions:[{
      type:'iteminfo',
      listeners: {            
        show:function(me, item, panel){                
          panel.setHtml('Stock Price: $'+ item.storeItem.get('price'));
        }
      } 
    }]
    
    Since my application has a controller i would like to know how i can control this itemInfo interaction with my controller?

    Thanks in advance!

  2. Try firing an event in the interaction. That may be listenable from the chart.

    Is this still the case in 2.1 RC2, Mitchell? It seems a shame because it makes interactions a bit more clunky to fit into the MVC architecture. You either have to go modify the interaction class (which is especially dicey if it's not your code), or you have to stick a bunch of code in your view that you'd rather keep clean of logic like that.

    It's also a problem with renderers on axes...
