subrela.plot.bokeh.draw_trace function

subrela.plot.bokeh.draw_trace(fig, trace_data, orientation='vertical', kws=None)[source]

Draw trace lines.

Parameters

  • fig (bokeh.plotting.figure.Figure) – Figure on which trace lines are drawn.

  • trace_data (pandas.DataFrame) – Data of trace lines returned by subrela.plot.get_trace_data function.

  • orientation ({'vertical', 'horizontal'}, optional) – Orientation of a tree. If 'vertical', the height direction of a tree corresponds to the y axis. If 'horizontal', it corresponds to the x axis.

  • kws (dict or None, optional) – Keyword arguments passed to bokeh.plotting.figure.Figure.multi_line method.

Returns

line (bokeh.models.renderers.GlyphRenderer) – Renderer for trace lines.

Notes

If neither key 'line_color' nor key 'color' is in kws, 'black' is set to 'line_color'. The default value for kws['line_width'] is 2.
