.. intro-start

Generates an `interactive visual analysis <https://en.wikipedia.org/wiki/Interactive_visual_analysis>`_ widget to analyze a pandas ``DataFrame`` in Jupyter notebooks.
It can display various different types of graphs with support for linked-brushing in interactive widgets.
This allows data exploration and cognition to be simple, even with complex multivariate datasets.

There is no need to create and style plots or interactivity - its all ready without any configuration.

.. code-block::

    conda install -c meffmadd pandas-visual-analysis

From Source
###########

To install this package from source, clone into the repository or download the `zip file <https://github.com/meffmadd/pandas-visual-analysis/archive/master.zip>`_
and run:

==================
Usage
==================

.. usage-start

Basic Usage
###############


Having a ``DataFrame``, for example:

.. code-block:: python

    import pandas as pd
    import ssl
    ssl._create_default_https_context = ssl._create_unverified_context
    url = "https://raw.githubusercontent.com/mwaskom/seaborn-data/master/mpg.csv"

    df = pd.read_csv(url)

you can just pass it to ``VisualAnalysis`` to display the default layout:

.. code-block:: python

    from pandas_visual_analysis import VisualAnalysis
    VisualAnalysis(df)

If you want to specify which columns of the ``DataFrame`` are categorical, just pass the ``categorical_columns`` option:

.. code-block:: python

    from pandas_visual_analysis import VisualAnalysis
    categorical = ["name", "origin", "model_year", "cylinders"]
    VisualAnalysis(df, categorical_columns=categorical)


Selection Types
###############

   :width: 70%
   :alt: selection types
   :align: center

|

By default a new selection replaces the old selection, however, it is also possible to add data points to the existing
selection by selecting the `Additive` selection type. By choosing the `Subtractive` selection newly selected
data points are removed from the selection.


Using DataSource
################

Instead of passing the ``DataFrame`` object directly to ``VisualAnalysis`` it is possible to use a ``DataSource`` object.
This enables linked-brushing across multiple notebook cells if the object is used across cells.

.. code-block:: python

    from pandas_visual_analysis import VisualAnalysis, DataSource

    data = DataSource(df)
    VisualAnalysis(data)

Later you can create a new analysis with the brushing still preserved
simply by using the same ``data`` object created earlier.

.. code-block:: python

    VisualAnalysis(data)

Using Layouts
#############

If you want to specify your own layout, you can do that by passing the ``layout`` parameter.
The parameter is a list of rows, where each row is in turn a list specifying the Widgets in that row.

.. code-block:: python

    from pandas_visual_analysis import VisualAnalysis

    VisualAnalysis(df,
        layout=[["Scatter", "Scatter"],
                ["ParallelCoordinates"]]
    )

Here, two scatter plots will share the first row while the second row only contains a parallel coordinates plot.
In order to see all the possible options you can call the ``widgets`` class-method of ``VisualAnalysis``.

.. code-block:: python

    VisualAnalysis.widgets()

This outputs the following list of possible plots:

.. code-block:: python

    ['Scatter',
     'ParallelCoordinates',
     'BrushSummary',
     'Histogram',
     'ParallelCategories',
     'BoxPlot']

Any of those can be part of the layout specification.
