时间序列
TimeSeries标签可用于标注时间序列数据。了解更多关于时间序列标注的信息，请访问时间序列模板页面。
注意：数据中的时间轴必须经过排序，否则TimeSeries标签将无法正常工作。
如需使用自动生成的索引作为时间轴，请不要使用timeColumn参数。
适用于以下数据类型：时间序列。
参数
| 参数 | 类型 | 默认值 | 描述 |
|---|---|---|---|
| name | string |
Name of the element | |
| value | string |
Key used to look up the data, either URLs for your time-series if valueType=url, otherwise expects JSON | |
| [valueType] | url | json |
url |
Format of time series data provided. If set to “url” then Label Studio loads value references inside value key, otherwise it expects JSON. |
| [sync] | string |
Object name to sync with. | |
| [timeColumn] | string |
Column name or index that provides temporal values. If your time series data has no temporal column then one is automatically generated. | |
| [timeFormat] | string |
Pattern used to parse values inside timeColumn, parsing is provided by d3, and follows strftime implementation |
|
| [timeDisplayFormat] | string |
Format used to display temporal value. Can be a number or a date. If a temporal column is a date, use strftime to format it. If it’s a number, use d3 number formatting. | |
| [durationDisplayFormat] | string |
Format used to display temporal duration value for brush range. If the temporal column is a date, use strftime to format it. If it’s a number, use d3 number formatting. | |
| [sep] | string |
"," |
Separator for your CSV file. |
| [overviewChannels] | string |
Comma-separated list of channel names or indexes displayed in overview. | |
| [overviewWidth] | string |
"25%" |
Default width of overview window in percents |
| [fixedScale] | boolean |
false |
Whether to scale y-axis to the maximum to fit all the values. If false, current view scales to fit only the displayed values. |

通道标签可用于标记时间序列数据
参数
| 参数 | 类型 | 默认值 | 描述 |
|---|---|---|---|
| column | string |
column name or index | |
| [legend] | string |
display name of the channel | |
| [units] | string |
display units name | |
| [displayFormat] | string |
format string for the values, uses d3-format:[,][.precision][f|%], - group thousands with separator (from locale): , (12345.6 -> 12,345.6) ,.2f (12345.6 -> 12,345.60).precision - precision for f|% type, significant digits for empty type:.3f (12.3456 -> 12.345, 1000 -> 1000.000).3 (12.3456 -> 12.3, 1.2345 -> 1.23, 12345 -> 1.23e+4)f - treat as float, default precision is .6: f (12 -> 12.000000) .2f (12 -> 12.00) .0f (12.34 -> 12)% - treat as percents and format accordingly: %.0 (0.128 -> 13%) %.1 (1.2345 -> 123.4%) |
|
| [height] | number |
height of the plot | |
| [strokeColor] | string |
"#f48a42" |
plot stroke color, expects hex value |
| [strokeWidth] | number |
1 |

| [markerColor] | string |
"#f48a42" |
plot stroke color, expects hex value |
| [markerSize] | number |
0 |
plot stroke width |
| [markerSymbol] | number |
circle |
plot stroke width |
| [timeRange] | string |
data range of x-axis / time axis | |
| [dataRange] | string |
data range of y-axis / data axis | |
| [showAxis] | string |
show or bide both axis | |
| [fixedScale] | boolean |
if false current view scales to fit only displayed values; if given overwrites TimeSeries’ fixedScale |
示例
针对从URL加载的CSV文件中存储的时间序列数据的标注配置，该文件包含3列：时间(time)、传感器1(sensor1)和传感器2(sensor2)。时间列以数字形式存储时间。
<View>
<TimeSeries name="device" value="$timeseries" valueType="url" timeColumn="time">
<Channel column="sensor1" />
<Channel column="sensor2" />
</TimeSeries>
<TimeSeriesLabels name="label" toName="device">
<Label value="Run" background="#5b5"/>
<Label value="Walk" background="#55f"/>
</TimeSeriesLabels>
</View>示例
针对存储在任务字段ts中的时间序列数据的标注配置，采用Label Studio JSON格式。时间字段以日期形式存储在timeformat字段中，默认情况下在图表上显示为完整日期格式。
<View>
<TimeSeries name="device" value="$ts" timeColumn="time" timeFormat="%m/%d/%Y %H:%M:%S">
<Channel column="sensor1" />
<Channel column="sensor2" />
</TimeSeries>
</View>
