Session / Data / Latency Trends

Log Scale

This option should be used when the range of your data is very broad. When checked, the values are displayed using a logarithmic scale rather than using the actual values so that data on the extreme ends of the scale can be viewed more effectively. For example, if you have data that ranges from the tens to the thousands, the data in the range of the tens will be neglected visually if you do not check this option.

 

 

 

Base at Zero

When this option is checked, zero is set as the as the Y axis minimum for all graph traces.

 

 

 

Time Range

Select a time range from the drop down menu varying from 2 Minutes to Last 7 Days, or display All Data. To specify a time range, click the ems_ellipsis00414.gif button.

By default, the time range end point is the current time. To change the time range end point, click the calendar_button00416.gif button and select a date and time from the calendar or enter the date and time in the text field using the following format: MMM dd, YYYY HH:MM. For example, Aug 21, 2011 12:24 PM.

Use the navigation arrows forbackward00417.gif to move forward or backward one time period. Note: The time period is determined by your selection from the Time Range drop-down menu.

Click Restore to Now to reset the time range end point to the current time.
