bqplot.marks.FlexLine¶

class bqplot.marks.FlexLine(**kwargs)[source]¶

Flexible Lines mark.

In the case of the FlexLines mark, scales for ‘x’ and ‘y’ MUST be provided. Scales for the color and width data attributes are optional. In the case where another data attribute than ‘x’ or ‘y’ is provided but the corresponding scale is missing, the data attribute is ignored.

name¶

user-friendly name of the mark

Type:	string (class-level attributes)

colors¶

List of colors for the Lines

Type:	list of colors (default: CATEGORY10)

stroke_width¶

Default stroke width of the Lines

Type:	float (default: 1.5)

Data Attributes

x¶

abscissas of the data points (1d array)

Type:	numpy.ndarray (default: [])

y¶

ordinates of the data points (1d array)

Type:	numpy.ndarray (default: [])

color¶

Array controlling the color of the data points

Type:	numpy.ndarray or None (default: None)

width¶

Array controlling the widths of the Lines.

Type:	numpy.ndarray or None (default: None)
