jquery flot: elenca tutti i dati e l'asse Y librarsi

Saluti Sono un novizio jquery e cercando di risolvere un problema che utilizza una versione di "turning-series.html" dalle flot esempi ufficiali, 1- Mi chiedo come posso girarlo dal display selezionato per visualizzare tutto dai miei set di dati. 2- Come modificare le mie opzioni in modo che quando il mouse supera il punto, visualizza il valore dell'asse Y?jquery flot: elenca tutti i dati e l'asse Y librarsi

//My data instance: 
var datasets = { 
     "1st input": { 
      label: "1st input", 
      data: [ 
      [1.250208e+12, 1339], 
      [1.2502944e+12, 1316],  
      [1.2503808e+12, 1379], 
      [1.2504672e+12, 1223], 
      ] 
     }, 
     "2nd input": { 
      label: "2nd input", 
      data: [ 
      [1.2503808e+12, 1324], 

      ] 
     }, 
    }; 


//old one, instead of displaying the selected ones from choiceContainer, I want to display all. 
    function showWhole() { 
     var data = []; 
     choiceContainer.find("option:selected").each(function() { 
      var key = $(this).attr("name"); 
      if (key && datasets[key]) 
       data.push(datasets[key]); 
     }); 

     if (data.length > 0) 
      $.plot($("#placeholder"), data, { 
       yaxis: {}, 
       xaxis: { mode: "time",minTickSize: [1, "day"],timeformat: "%d/%m/%y"},"lines": {"show": "true"},"points": {"show": "true"},clickable:true,hoverable: true 
      }); 
    }

ho preso l'esempio trasformando-series.html dal sito FLOT e ha apportato alcune modifiche. Copia e incolla quanto segue in un nuovo file HTML ed eseguilo - funziona in Firefox, non testato in IE.
