class LabelSet(**kwargs)[source]¶

Bases: bokeh.models.annotations.TextAnnotation

Render multiple text labels as annotations.

LabelSet will render multiple text labels at given x and y coordinates, which can be in either screen (pixel) space, or data (axis range) space. In this case (as opposed to the single Label model), x and y can also be the name of a column from a ColumnDataSource, in which case the labels will be “vectorized” using coordinate values from the specified columns.

The label can also be configured with a screen space offset from x and y, by using the x_offset and y_offset properties. These offsets may be vectorized by giving the name of a data source column.

Additionally, the label can be rotated with the angle property (which may also be a column name.)

There are also standard text, fill, and line properties to control the appearance of the text, its background, as well as the rectangular bounding box border.

The data source is provided by setting the source property.

y¶

property type: NumberSpec

The y-coordinates to locate the text anchors.
