Better copy & paste of array:

		sorteddaystoshow.sort();
        var from = sorteddaystoshow[0];
        var to = sorteddaystoshow[1];
        if (options.order === report_plugins.consts.ORDER_NEWESTONTOP) {
          sorteddaystoshow.reverse();
        }
        console.warn(loadeddays, sorteddaystoshow.length, sorteddaystoshow, from, to);
