The lower-left pane of Analysis Console contains the Chart Tree, which lists all charts that have been saved for an assessment. Any Analysis Console instance is always associated with a single saved VoIP Readiness assessment.
The first charts listed in the Chart Tree are chart starters: pre-defined charts of particular performance metrics, such as Jitter Buffer Loss. You can add other data streams to these charts, including other types of measurements (such as Lost Data) and measurements from other call groups. It is a good idea to make your charts based on chart starters, which perform a lot of the work involved in creating a chart.
Chart starters define parameters and build a chart from them. For example, the “Call Quality for Worst 5 Call Groups” chart starter builds a chart that shows key performance metrics from the five call groups with the lowest call quality scores. Double-click any chart starter in the Chart Tree to generate a chart.
Just below the list of pre-defined charts, charts you already generated and saved appear under the heading “Your Charts.” Double-click any saved chart to view it.
When you save a chart, you are saving the chart parameters, such as which call groups to include and which data streams to chart. You are not, however, saving the data, which is dynamically taken from the assessment database. If you run an assessment again after saving a chart, the next time you look at that chart, it reflects data from the current assessment run, not from the initial run.
