Bug: None of the live charts shown on "Status -> Monitor" page.

Hello Marc,
As I told you in one my mails that I was getting a bug that none of the Live Charts on "Status -> Monitor" page were shown in Google Chrome (even in latest version) in Ubuntu.

Line #1173 of  "js/server_status_monitor.js"  :
chartObj.chart = $.jqplot('gridchart' + runtime.chartAI, series, settings);
throws an exception "Canvas dimension not set".
Please have a look on this.
