## About the labeling configuration

All labeling configurations must be wrapped in [View](/tags/view.html) tags.

Use the `visibleWhen` parameter with the [View](/tags/view.html) tag to create a section of the labeling configuration that is only visible when no region is selected:
```xml
<View visibleWhen="no-region-selected"
          style="height:120px">
``` 

When that section of the labeling interface is visible, annotators can use the [TimeSeriesLabels](/tags/timeserieslabels.html) control tag to label specific regions on the time series data:
```xml
        <TimeSeriesLabels name="label" toName="ts">
            <Label value="Region" background="#5b5"/>
        </TimeSeriesLabels>
    </View>
```

Use the `visibleWhen` parameter with a different [View](/tags/view.html) tag to create a section of the labeling interface that is visible only when a region is selected:
```xml
<View visibleWhen="region-selected" style="height:120px">
```

When that section of the labeling interface is visible, annotators can use the [Rating](/tags/rating.html) control tag to select a 10 star rating for the selected region:
```xml
<Rating name="rating" toName="ts"
                maxRating="10" icon="star"
                perRegion="true"/>
```
The `perRegion="true"` parameter means that this rating only applies to the selected region.

Still within that region-specific section of the labeling interface, annotators can use the [Choices](/tags/choices.html) control tag to select a choice for the selected region:
```xml
        <Choices name="choices" toName="ts"
                 showInline="true" required="true"
                 perRegion="true">
            <Choice value="Good"/>
            <Choice value="Medium"/>
            <Choice value="Poor"/>
        </Choices>
    </View>
```

Use the [TimeSeries](/tags/timeseries.html) object tag and the Channel tag to display the TimeSeries data and channels to the annotators:
```xml
    <TimeSeries name="ts" valueType="url" value="$csv"
                sep="," timeColumn="time">
        <Channel column="signal_1"
                 strokeColor="#17b" legend="Signal 1"/>
        <Channel column="signal_2"
                 strokeColor="#f70" legend="Signal 2"/>
    </TimeSeries>
```
