About the labeling configuration

All labeling configurations must be wrapped in View tags.

Use the visibleWhen parameter with the View 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 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 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 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 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 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>
