class `bokeh.models.annotations.` `Label`(**kwargs)

  Bases: `bokeh.models.annotations.TextAnnotation`

  Render a single text label as an annotation.

  `Label` will render a single text label at given `x` and `y` coordinates, which can be in either screen (pixel) space, or data (axis range) space.

  The label can also be configured with a screen space offset from `x` and `y`, by using the `x_offset` and `y_offset` properties.

  Additionally, the label can be rotated with the `angle` property.

  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.

  `angle`

    property type: `Angle`

    The angle to rotate the text, as measured from the horizontal.

    Warning

    The center of rotation for canvas and css render_modes is different. For render_mode=”canvas” the label is rotated from the top-left corner of the annotation, while for render_mode=”css” the annotation is rotated around it’s center.

  `angle_units`

    property type: `Enum` ( `AngleUnits` )

    Acceptable values for units are `"rad"` and `"deg"`

  `background_fill_alpha`

    property type: `NumberSpec`

    The fill alpha values for the text bounding box.

  `background_fill_color`

    property type: `ColorSpec`

    The fill color values for the text bounding box.

  `border_line_alpha`

    property type: `NumberSpec`

    The line alpha values for the text bounding box.

  `border_line_cap`

    property type: `Enum` ( `LineCap` )

    The line cap values for the text bounding box.

  `border_line_color`

    property type: `ColorSpec`

    The line color values for the text bounding box.

  `border_line_dash`

    property type: `DashPattern`

    The line dash values for the text bounding box.

  `border_line_dash_offset`

    property type: `Int`

    The line dash offset values for the text bounding box.

  `border_line_join`

    property type: `Enum` ( `LineJoin` )

    The line join values for the text bounding box.

  `border_line_width`

    property type: `NumberSpec`

    The line width values for the text bounding box.

  `render_mode`

    property type: `Enum` ( `RenderMode` )

    Note

    The CSS labels won’t be present in the output using the “save” tool.

    Warning

    Not all visual styling properties are supported if the render_mode is set to “css”. The border_line_dash property isn’t fully supported and border_line_dash_offset isn’t supported at all. Setting text_alpha will modify the opacity of the entire background box and border in addition to the text. Finally, clipping Label annotations inside of the plot area isn’t supported in “css” mode.

  `text`

    property type: `String`

    The text value to render.

    Datetime values are also accepted, but note that they are immediately converted to milliseconds-since-epoch.

  `x_offset`

    property type: `Float`

    Offset value to apply to the x-coordinate.

    This is useful, for instance, if it is desired to “float” text a fixed distance in screen units from a given data position.

  `x_range_name`

    property type: `String`

    A particular (named) x-range to use for computing screen location when rendering an annotation on the plot. If unset, use the default x-range.

  `x_units`

    This is useful, for instance, if it is desired to “float” text a fixed distance in screen units from a given data position.

class `bokeh.models.annotations.` `LabelSet`(**kwargs)

  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.

  `angle`

    property type: `AngleSpec`

    The angles to rotate the text, as measured from the horizontal.

    Warning

    The center of rotation for canvas and css render_modes is different. For render_mode=”canvas” the label is rotated from the top-left corner of the annotation, while for render_mode=”css” the annotation is rotated around it’s center.
