This module provides the Scatter item of the Plot.
-
class
Stats(statslist=None)[source]
Class to define a set of statistic relative to a dataset
(image, curve…).
The goal of this class is to avoid multiple recalculation of some
basic operations such as filtering data area where the statistics has to
be apply.
Min and max are also stored because they can be used several time.
- Parameters
statslist (List) – List of the Stat object to be computed.
-
calculate(item, plot, onlimits)[source]
Call all Stat object registered and return the result of the
computation.
- Parameters
item – the item for which we want statistics
plot – plot containing the item
onlimits (bool) – True if we want to apply statistic only on
visible data.
- Return dict
dictionary with Stat name as ket and result
of the calculation as value
-
class
StatBase(name, compatibleKinds=('curve', 'image', 'scatter', 'histogram'), description=None)[source]
Base class for defining a statistic.
- Parameters
name (str) – the name of the statistic. Must be unique.
compatibleKinds (List[str]) – The kind of items (curve, scatter…) for which the statistic apply.
-
calculate(context)[source]
compute the statistic for the given StatsContext
- Parameters
context (_StatsContext) –
- Return dict
key is stat name, statistic computed is the dict value
-
getToolTip(kind)[source]
If necessary add a tooltip for a stat kind
- Parameters
kind (str) – the kind of item the statistic is compute for.
- Returns
tooltip or None if no tooltip
-
class
Stat(name, fct, kinds=('curve', 'image', 'scatter', 'histogram'))[source]
Create a StatBase class based on a function pointer.
- Parameters
name (str) – name of the statistic. Used as id
fct – function which should have as unique mandatory parameter the
data. Should be able to adapt to all kinds defined as
compatible
kinds (tuple) – the compatible item kinds of the function (curve,
image…)
-
calculate(context)[source]

- Parameters

class
StatDelta[source]
Compute the delta between minimal and maximal on data
-
