Thanks @loli, your solution was very useful for me. In my case:

if (contentcsv.length<1) { //if contentcsv is empty
    contentcsv = ",\n0,0";
    var title = "no data available";
}
else {title = "My Title";}

g = new Dygraph(
document.getElementById("graph"),
contentcsv,
{ 
    title: title,
    ylabel: 'Values',
    xlabel: 'Date',
  })
