# # Data Annotations

Graphical objects can include annotations for data sets. These can be any kind of text or variables for either timestamps or data points. You can configure these properties in the *Remarks* section of the *Datasets* tab.

## # Time-based Variables for Data Annotation

The following variables are supported:

Variable | Description | Example |
---|---|---|

`${v0}` or `${timestamp}` | Timestamp | 08.11.2018 12:17:16 |

`${v0 (y)}` | only year | 2018 |

`${v0 (M)}` | year and month | Nov 2018 |

`${v0 (d)}` | full date | 08.11.2018 |

`${v0 (h)}` | date and hours | 08.11.2018 12 |

`${v0 (m)}` | date, hours and minutes | 08.11.2018 12:17 |

`${v0 (s)}` | full timestamp, same as v0 | 08.11.2018 12:17:18 |

`${v0 (MM)}` | only month | 11 |

`${v0 (dd)}` | only day of month | 08 |

`${v0 (HH)}` | only hours | 12 |

`${v0 (mm)}` | only minutes | 17 |

`${v0 (ss)}` | only seconds | 18 |

`${v0 (dd)}/${v0 (MM)}/${v0 (y)} ${v0 (HH)}-${v0 (mm)}-${v0 (ss)}` | Formatted timestamp | 08/11/2018 12-17-16 |

## # Data Values in Annotations

When using data values in annotations/remarks, please keep in mind that data variables change depending on the projection type used.

### # Time-based Projection

For datasets with a time-based data source

Variables | Description | Example |
---|---|---|

`${v1}` or `${value}` | Value | 308,258911 |

`${v1 (2)}` or `${value (2)}` | Value rounded to given amount of digits, here 2 | 308,26 |

`${v0 (d)} ${value (2)[m.ü.A]}` | Formatiertted timestamp, value and static text | 08-11-2018 308,26 [m.ü.A] |

### # Parametric Projection

Graphs in which ordinate value 1 is in dependence to value 2, see parametric graph)

Parameter | Description | Example |
---|---|---|

`${v1}` or `${x}` | Value 1 | 4,1234114 |

`${v2}` or `${y}` | Value 2 | 10,5678 |

`${v1 (0)}` or `${x (0)}` | Value 1, 0 decimal places | 4 |

`${v2 (0)}` or `${y (0)}` | Value 2, 0 decimal places | 10 |

`${v0 (d)} (${x (0)} mm,${y (0)} mm)` | Formatted timestamp with value pair | 08-11-2018 (4 mm,10 mm) |

### # Minimum-Maximum Projection

Annotations are displayed on the upper and lower borders (see minimum-maximum projection)

Parameter | Description | Example |
---|---|---|

`${v1}` or `${min}` | Minimum | 5,7854 |

`${v2}` or `${max}` | Maximum | 105,332 |

`${v1 (0)}` or `${min (0)}` | Minimum rounded to 0 decimal places | 6 |

`${v2 (1)}` or `${max (1)}` | Maximum rounded to 1 decimal place | 105,3 |

### # Interval Projection

See also Interval projection

Parameter | Description | Example |
---|---|---|

`${v1}` or `${min}` | Minimum | 5,7854 |

`${v2}` or `${mid}` | Second Parameter (in this case, average) | 50,198 |

`${v3}` or `${max}` | Maximum | 105,332 |

`${v1 (0)}` or `${min (0)}` | Minimum rounded to 0 decimal places | 6 |

`${v2 (1)}` or `${mid (1)}` | Average rounded to 1 decimal places | 50,2 |

`${v3 (1)}` or `${max (1)}` | Maximum rounded to 1 decimal places | 105,3 |

### # Combining multiple time series

See also the chapter to multi file selection

Parameter | Description | Example |
---|---|---|

`${v2}` | Value | 308,258911 |

`${v2 (2)}` | Value rounded to 2 decimal places | 308,26 |
