bokeh.models.markers¶

Glyph renderer models for displaying simple scatter-type markers on Bokeh plots.

class Asterisk(**kwargs)¶

Bases: bokeh.models.markers.Marker

Render asterisk ‘*’ markers.

Example

{
  "angle": {
    "units": "rad",
    "value": 0.0
  },
  "fill_alpha": {
    "value": 1.0
  },
  "fill_color": {
    "value": "gray"
  },
  "id": "68cbe00d-300f-499d-b75f-6e1b0216f3fb",
  "line_alpha": {
    "value": 1.0
  },
  "line_cap": "butt",
  "line_color": {
    "value": "black"
  },
  "line_dash": [],
  "line_dash_offset": 0,
  "line_join": "miter",
  "line_width": {
    "value": 1
  },
  "name": null,
  "size": {
    "units": "screen",
    "value": 4
  },
  "tags": [],
  "visible": true,

class Circle(**kwargs)¶

Bases: bokeh.models.markers.Marker

Render circle markers.

Example

source: tests/glyphs/Circle.py

radius¶

property type: radius:DistanceSpec(units_default=’data’)

The radius values for circle markers (in “data space” units, by default).

Note

Circle markers are slightly unusual in that they support specifying a radius in addition to a size. Only one of radius or size should be given.

Warning

Note that Circle glyphs are always drawn as circles on the screen, even in cases where the data space aspect ratio is not 1-1. In all cases where radius values are specified, the “distance” for the radius is measured along the dimension specified by radius_dimension. If the aspect ratio is very large or small, the drawn circles may appear much larger or smaller than expected. See issue 626 for more information.

radius_dimension¶

property type: radius_dimension:Enum(‘x’, ‘y’)

What dimension to measure circle radii along.

When the data space aspect ratio is not 1-1, then the size of the drawn circles depends on what direction is used to measure the “distance” of the radius. This property allows that direction to be controlled.

radius_units¶: property type: radius_units:Enum(‘screen’, ‘data’)
