cycle only for the delta duration.
When you click Start Updating, the chart re-renders itself to show the new values that are

Time Line Chart Style
Time Line chart style (default) enables you to view the plotting of data points for a fixed time interval.
In addition, when data points for multiple metrics are plotted with different collection frequencies,
their relationships with the time intervals are displayed correctly.
Only data points that are collected during the specified interval are retrieved from the database
and plotted on the graph. Data points are not plotted for intervals of time where data collection
has failed. Hence, there can be discontinuity in the graph plotted. In the sense, the graph for that
particular duration displays a blank graph area, indicating a failure in data collection. The data
points are plotted again once data collection resumes.
Moving Average Chart Style
The Moving Average chart style enables you to view the average performance of the selected
components for a specified time interval. The current average (Moving Average) value is calculated
