• TimeZoom
  

  TimeZoom is a feature enhancement for Line charts to make them more readable. When the data points are too many at a particular time stamp that it gets difficult to identify and distinguish the data points from one another, TimeZoom feature increases the time granularity and zooms into the chart to sparsely place the data points. For instance, if the time stamp records data at an hourly rate, applying the TimeZoom displays the data points that are recorded at a shorter interval say half hour and place the data points at a comprehensible distance. TimeZoom is represented in the form of a horizontal scroll bar, which can zoom out and in as you move it. It is placed at the bottom of the widget.

  Following widgets are enhanced with Timezoom feature:

  • Wifi Client Count (drill down from Wifi Overview)
  • Wifi Interference and Noise Performance (drill down from Wifi Overview)
  • Device Health History
  • IPSLA History
  • HTTP Response Time
  • Timeseries Data
  • Application Response Time (drill down from Application Response Overview)
• Filtering options that are applicable for Network Performance Insight Dashboards.

  The filter options and list differ based on the different types of Network Performance Insight Dashboards.
