Graphsense.com offers a firefox plugin that helps you create charts to visually analyze your adsense data right inside your Adsense Control Panel.

However, it generates those charts by downloading and sending your reports to it's own servers.

function phoneHome(zeData) {
//console.log(zeData);
//console.log(utf16to8(zeData));
//alert('encodeURI: ' + encodeURI(zeData));
GM_xmlhttpRequest({
   method: 'POST',
   url: 'http: //www.graphsense.com/input.php',
   headers: {
   'Content-type' : 'application/x-www-form-urlencoded'
   },
   data: 'data='+encodeURI(zeData),
   onload: function(responseDetails) {
   updateAdGFX(responseDetails.responseText);
   }
});
return true;
}

Adsense terms clearly prohibits you from sharing your report data with other.
