You can specify date ranges for which a trend group chart's data will be displayed on the Observer Problems page. Note that specifying a date range on the Problems page only changes your current view of the trend group data and does not affect how that data is displayed on the Observer Overview page. Procedure To specify a date range for a trend group chart, follow these steps: 1.   Log into Observer  and click   >  Problems  to navigate to the  Problems  page. 2.  Select the trend group you want to display from the dropdown at the top of the page next to "Raw Data". 3.  By default, the  start date  for the data displayed will be today's date. To change the start date, click the   icon in the upper left-hand corner of the page. Then, select a new start date and click  OK .  NOTE :  If no data is available for the start date you selected, Observer will adjust the start date by looking back in time for a date with available data. 4.  Choose a time window from the dropdown next to the   icon. The trend group chart will then be rendered to display data for the range you have specified. For example, selecting a start date of  August 23  and a time window of  1 week  will display all available data  from August 23 through August 29 . Alternatively, you can specify starting and ending dates/times in the  From  and  To  boxes at the top right-hand side of the trend group chart.    Next steps Change the zoom interval for a trend group chart Similar topics Contact Perspectium Support US:  1 888 620 8880 UK:  44 208 068 5953 support@perspectium.com
