Raphael (which is the Javascript library used for the graphing) creates VML markup (with rvml: tags) in IE 8 instead of SVG markup; so the script needs to handle that situation as well. You could try the fix described below. It should also work in lower versions of IE.In scp/js/dashboard.inc.js...Look for the bit of code below: // Change axis labels from Unix epoch $('tspan', $('#line-chart-here')).each(function(e) { var text = this.firstChild.textContent; if (parseInt(text) > 10000) this.firstChild.textContent = $.datepicker.formatDate('mm-dd-yy', new Date(parseInt(text) * 86400000)); }); And the code below right after it: // VML version for IE 8 and lower $('textpath', $('#line-chart-here')).each(function(e) { var text = this.string; if (parseInt(text) > 10000) this.string = $.datepicker.formatDate('mm-dd-yy', new Date(parseInt(text) * 86400000)); });
