It seems that the problem is that you're manipulating an innerHTML that
contains an iframe:
document.getElementById('data').innerHTML += "<table
class='table'>" + serverdata[1] + "</table>";
When running this line for the 2nd time, the innerHTML already contains the
iframe with the 1st server charts.
When you reassign the innerHTML it messes up the iframe and clears its body
node.
There is a simple work around.
Instead of modifying the same innerHTML over and over again, create a new
container using createElement and appendChild.
Something like:
var table=document.createElement('table');
// TODO: set properties of table here
table.innerHTML = serverdata[1];
document.getElementById('data').appendChild(table);
Hope this works,
