class Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection

Bases: object

A class to manage labels on the chart.

Overview

Methods

Name Description
CreateAndAddLabel Creates a new label and adds it to the chart at a specified position, where the label_text parameter is optional.
CreateLabelOnSegment Create a label on the segment of the dataset starting from the data point at a specified distance along the segment.
CreateLabelsAtXCoordinate Creates label(s) on the dataset at a specified X coordinate.
CreateLabelsAtYCoordinate Creates label(s) on the dataset at a specified Y coordinate.
DeleteLabel Deletes a label from a specific position in the chart.

Properties

Name Description
Labels Gets an IEnumerable of ILabelInfo objects, which contain information about the underlying label

Property detail

property LabelCollection.Labels : Iterable[Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo] | None

Gets an IEnumerable of ILabelInfo objects, which contain information about the underlying label

Method detail

LabelCollection.CreateAndAddLabel(x_anchor: Ansys.Core.Units.Quantity, y_anchor: Ansys.Core.Units.Quantity, label_text: str) → Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo

Creates a new label and adds it to the chart at a specified position, where the label_text parameter is optional.
The default label text is: “x: <x_value>, y: <y_value>” (example: “x: 0.3497, y: 1.9821”).
An InvalidOperationException will be thrown when creating a Label at a location already assigned to another Label.

LabelCollection.CreateLabelOnSegment(data_point_index: int, fractional_distance: float) → Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo

Create a label on the segment of the dataset starting from the data point at a specified distance along the segment.
Distance values are fractional going from 0 to 1 (first datapoint at 0) along the length of the segment
An ArgumentException will be thrown when creating a Label at a location already assigned to another Label.

LabelCollection.CreateLabelsAtXCoordinate(x_anchor: Ansys.Core.Units.Quantity) → List[Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo]

Creates label(s) on the dataset at a specified X coordinate.
This API may return multiple `LabelInfo` references in case the corresponding dataset has more than one Y-value for the given X-value (for eg. Spiral graphs).
Each `LabelInfo` reference corresponds to the multiple anchor positions thus obtained.
An ArgumentException will be thrown when creating a Label at a location already assigned to another Label.

LabelCollection.CreateLabelsAtYCoordinate(y_anchor: Ansys.Core.Units.Quantity) → List[Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo]

Creates label(s) on the dataset at a specified Y coordinate.
This API may return multiple `LabelInfo` references in case the corresponding dataset has more than one X-value for a given Y-value.
Each `LabelInfo` reference corresponds to the multiple anchor positions thus obtained.
An ArgumentException will be thrown when creating a Label at a location already assigned to another Label.

LabelCollection.DeleteLabel(label: Ansys.Mechanical.DataModel.Utilities.Charts.LabelCollection.LabelInfo) → None

Deletes a label from a specific position in the chart.
An InvalidOperationException will be thrown when deleting a Label that does not exist.
