12.2 Measurements Widgets
Measurements widgets display quantitative data from monitoring objects — charts, live values, error counters, and protocol-specific readouts. Most chart widgets require a linked Time range widget (see Section 12.1) to define the display interval.
Bar Charts
The Bar charts widget displays bar charts for one or more parameters of selected monitoring objects. It requires a linked Time range widget to define the time interval over which values are aggregated.
Figure 272. Bar charts widget parameters
The widget has the following parameters:
| Parameter | Description |
|---|---|
| Monitoring objects | Select one or more monitoring objects whose parameters should be shown on the chart |
| Value on the bar chart | Aggregation type: Minimal, Average, or Maximal |
| Analyzers and measures | Table defining which analyzer parameters to display. Click New record to add a row, then select the analyzer and parameters in the Measurements column. The analyzer can be changed via the dropdown in the Analyzer column. |

Bitrate Charts
The Bitrate charts widget shows how the bitrates of services within an MPEG TS transport stream change over time. Each service is rendered in a distinct color, making it easy to compare service bitrates side by side. The widget requires a linked Time range widget.
Figure 274. Bitrate charts widget parameters
| Parameter | Description |
|---|---|
| Object | The MPEG TS monitoring object for which the chart is generated |
| Points count | Number of intervals on the time axis. A smaller value produces a finer time scale. |
| Show legend | Toggle the chart legend on or off |
When hovering over the chart, a tooltip displays the exact numerical values for the time point indicated by the cursor.

Current Values
The Current values widget displays the live numerical values of selected parameters, refreshed at a configurable interval. This is useful for keeping an at-a-glance view of key metrics directly in the workspace.
Figure 276. Current values widget parameters
| Parameter | Description |
|---|---|
| Rotation speed | Refresh interval for the displayed values. Default: 15 seconds |
| Object | Monitoring object. Select from the list. |
| Analyzer | Analyzer for the selected monitoring object |
| Measures — Measure | Parameter to display. The list shows parameters available for the selected analyzer. |
| Measures — Metric prefix | Unit prefix: kilo, mega, or giga |
To add more parameters, click Add measure. Each added row can be configured independently.

Error Counter
The Error counter widget displays cumulative error counts for MPEG monitoring objects based on selected ETSI TR 101 290 parameters. The counter can be configured to reset automatically at a specified interval.
Figure 278. Error counter widget parameters
| Parameter | Description |
|---|---|
| Object | MPEG monitoring object. Select from the list. |
| Reset counter | Interval in seconds after which error counters are reset. Must be a non-zero value. |
| Measures — Analyzer | Select an ETSI TR 101 290 analyzer from the list |
| Measures — Measurements | Select one or more parameters for the chosen analyzer |
To add more parameter rows, click Add measure.

EWS/EEWS
The EWS/EEWS widget displays the protocol parameters of the Emergency Warning System (EWS) or Extended Emergency Warning System (EEWS) for MPEG TS monitoring objects. It is used to monitor active emergency broadcast conditions.
Figure 280. EWS/EEWS widget parameters
| Parameter | Description |
|---|---|
| Object | MPEG TS monitoring object with EWS/EEWS content. Select from the list. |
| Analyzer | Select the appropriate EWS or EEWS analyzer |
| Font size | Font size for the parameter list items |

Line Chart
The Line chart widget displays one or more parameters as a line chart over time. It requires a linked Time range widget. The vertical axis scale is set automatically.
Figure 282. Line chart widget parameters
| Parameter | Description |
|---|---|
| Object | Monitoring object whose parameters are displayed |
| Linear box plot metrics | Averaged value types to show: Minimal, Average, Maximal. To show only raw values, enable Disable box plots. |
| Analyzers and measures | Table of analyzer parameters to plot. Click New record to add a row. |
| Show no signal on graph | Mark periods where no signal is present on the chart |
| Show legend on graph | Display the parameter legend on the chart |
| Disable box plots | Switch between candlestick mode and plain line mode |
| Enable background | Display a grid background behind the chart |
| Enable statistics | Show min/max/average values below the legend |
Figure 283. Line chart widget visualization
When viewing a long time range, the chart automatically switches to candlestick (box plot) mode (Figure 284). This compact format shows the minimum, maximum, and average values within each interval, making it possible to spot value ranges over extended periods without losing detail.

Mean Values
The Mean values widget displays the average values of selected parameters over the interval defined by a linked Time range widget. When multiple monitoring objects or services are configured, the widget cycles through them at a configurable rotation speed.
Figure 285. Mean values widget parameters
| Parameter | Description |
|---|---|
| Rotation speed | Interval between switching to the next service. Default: 15 seconds |
| Object | Monitoring object. Select from the list. |
| Analyzer | Analyzer for the selected monitoring object |
| Measures — Measure | Parameter to display. The list shows parameters for the selected analyzer. |
| Measures — Metric prefix | Unit prefix: kilo, mega, or giga |
To add more parameters, click Add measure.
In the visualization (Figure 286), the current service name is shown in green. Use the navigation buttons (red arrow) to switch between services manually.

SCTE-35/104 Table
The SCTE-35/104 table widget displays a list of SCTE-35 or SCTE-104 splice messages received by a monitoring object. It requires a linked Time range widget to define the message display interval.
Figure 287. SCTE-35/104 widget parameters
| Parameter | Description |
|---|---|
| Object type | Message type: SCTE-35 (for network streams) or SCTE-104 (for studio signals) |
| Object | Monitoring object matching the selected type |
| Font size | Font size for the list items |
The table columns can be customized to suit your needs. Click the column configuration button to open the Table configuration window (Figure 289), where you can enable or disable individual columns. For a description of each column, refer to the SCTE-35/104 standard. To persist your column configuration across sessions, enable the Recognize filter history option.
