# `b2_plotter`



## Description

The `b2_plotter` package consists of the class Plotter(), whereby several plots based on numpy arrays and pandas dataframes can be created easily from interpretation of Belle II ROOT mDST files. 



## Releases



### Version 4.0.5

- Bugfix getSigEff calculation with scale parameter



### Version 4.0.4

- Add scale/bgscale functionality to plotFom, plotStep, getPurity, getSigEff (latter 2 renamed for consistency)



### Version 4.0.3

- Use numpy's std instead of mean and add parenthesis to cut f string



### Version 4.0.2

- Shift the data sidebands (when blinding is enabled) by +/- 3 sigma



### Version 4.0.1

- Remove the actual duplicate data label..



### Version 4.0.0

- Remove duplicate data label in plotData()



### Version 3.0.9

- Again bugfix data plotting



### Version 3.0.8 

- Bugfix data plotting



### Version 3.0.7

- Add signalregion and massvar to constructor call and remove it as a parameter from plotFom, getpurity, getsigeff

- Split up plot into two functions, plotMC and plotData

    - Add blinding functionality to plotData function



### Version 3.0.6

- Add blinding to invariant mass distributions through introduction of addBlinding parameter to initialization



### Version 3.0.5

- Update example.ipynb



### Version 3.0.4

- Bugfix missing call to colors parameter



### Version 3.0.3

- Make colors() for plot an argument with default for all MC types, so that

it can be overridden if needed



### Version 3.0.2

- Bugfix additional root_pandas call



### Version 3.0.1

- Remove deprecated root_pandas library, replace with uproot

- Update main() with a working example usage for xi03pi

- Add unit tests



### Version 2.0.9 

- 2.0.8 bugfix (missing comma)



### Version 2.0.8

- Remove scaled signal feature -- will work on this on a later release

- Specify the colors of plot() histograms since the signal was defaulting to grey



### Version 2.0.7 

- Bugfix to version 2.0.6, where scaled signal was not properly showing



### Version 2.0.6

- Change functions to return plots instead of displaying them, and remove interactive feature

- Add a scaled signal histogram to the plot function

- Update dynamic range calculation in plotFom for isGreaterThan = False cuts to prevent division by zero errors



### Version 2.0.5

- Add `cuts` argument to `plotFom`



### Version 2.0.4

- Last push didnt include changes, so include bugfix

- Add dist/, .pytest_cache, and .ipynb_checkpoints to git ignore 



### Version 2.0.3

- Bugfix call to numpy.histogram() (was called np.histogram)



### Version 2.0.2

- Implement unit tests for constructor TypeError raises



### Version 2.0.1

- Implement data plotting in plot()

- Implement unit tests for functions in non-interactive mode



### Version 1.0.9

- Set myrange = () in plotFom to enable the dynamic range calculation from v.1.0.5 if the user does not provide a range.



### Version 1.0.8

- Implement dynamic range calculation in plotStep 

- Bugfix labels not showing up on plotFom for myrange = () (default)

- Bugfix get_sigeff (missing period)



### Version 1.0.7

- Bugfix (remove () from numpy.size, as size is a property, not a method)



### Version 1.0.6

- Remove deprecated var total_bkg from plotFom()



### Version 1.0.5 

- Create example files for interactive session

- Change massvar name to be consistent (massVar in get_purity but massvar in FOM, etc)

- Implement dynamic range calculation in plotFom



### Version 1.0.4

- Bugfix main and implement a for loop to plot multiple variables

- Create usage details in README.md



### Version 1.0.3 

- Change readme such that recent versions are at the top 

- Remove `plotBias` function, as it is very niche

- Remove unused parameter `myrange` in get_sigeff and get_purity

- Add main() function 

- Add interactivity boolean in constructor call to decide whether or not to save plots to a .png or show them directly



### Version 1.0.2 

- Edit README.md

- Remove tests/ directory (unit tests are not particularly useful for this package)

- Rename directories so imports are more intuitive



### Version 1.0.1

- Add unit tests

- Switch backend to hatchling

- Move metadeta to pyproject.toml and clean it up

- Remove brackets from LICENSE.txt

- Create tests/ directory



### Version 1.0.0

Initial launch.
