bqplot.marks.Hist¶
-
class
bqplot.marks.
Hist
(**kwargs)[source]¶ Histogram mark.
In the case of the Hist mark, scales for ‘sample’ and ‘count’ MUST be provided.
-
icon
¶ font-awesome icon for that mark
Type: string (class-level attribute)
-
name
¶ user-friendly name of the mark
Type: string (class-level attribute)
-
bins
¶ number of bins in the histogram
Type: nonnegative int (default: 10)
-
normalized
¶ Boolean attribute to return normalized values which sum to 1 or direct counts for the count attribute. The scale of count attribute is determined by the value of this flag.
Type: bool (default: False)
-
colors
¶ List of colors of the Histogram. If the list is shorter than the number of bins, the colors are reused.
Type: list of colors (default: CATEGORY10)
-
stroke
¶ Stroke color of the histogram
Type: Color or None (default: None)
-
opacities
¶ Opacity for the bins of the histogram. Defaults to 1 when the list is too short, or the element of the list is set to None.
Type: list of floats (default: [])
-
midpoints
¶ midpoints of the bins of the histogram. It is a read-only attribute.
Type: list (default: [])
-
Data Attributes
-
sample
¶ sample of which the histogram must be computed.
Type: numpy.ndarray (default: [])
-
count
¶ number of sample points per bin. It is a read-only attribute.
Type: numpy.ndarray (read-only)
Notes
- The fields which can be passed to the default tooltip are:
- midpoint: mid-point of the bin related to the rectangle hovered on count: number of elements in the bin hovered on bin_start: start point of the bin bin-end: end point of the bin index: index of the bin
