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

string (class-level attributes) – user-friendly name of the mark

colors

list of colors (default: CATEGORY10) – List of colors for the Lines

stroke_width

float (default: 1.5) – Default stroke width of the Lines

Data Attributes
x

numpy.ndarray (default: []) – abscissas of the data points (1d array)

y

numpy.ndarray (default: []) – ordinates of the data points (1d array)

color

numpy.ndarray or None (default: None) – Array controlling the color of the data points

width

numpy.ndarray or None (default: None) – Array controlling the widths of the Lines.
