AlloViz.AlloViz.Elements.Element#

class AlloViz.AlloViz.Elements.Element(data, parent, index=None, columns=None, dtype=None, copy=True)[source]#

Bases: DataFrame

Base class for network storage and representation

This class extends pandas.DataFrame with a view() method (and related private methods) to visualize the networks on the protein structures, besides storing the analyzed data. It uses the private methods _get_colors() and _show_cbar() to establish the color scale and represent it as a colorbar, respectively, and _get_nv() to retrieve information about the protein structure to show and/or the visualization widget to add the network elements to. The different elements, cylinders for Edges and spheres for Nodes, are represented using the corresponding child class’ _add_element private method.

Once a class instance is created, the private attribute _parent must be established with the Protein or Delta object the information belongs to, as it is needed for representation.

Attributes:
T

The transpose of the DataFrame.

at

Access a single value for a row/column label pair.

attrs

Dictionary of global attributes of this dataset.

axes

Return a list representing the axes of the DataFrame.

columns

The column labels of the DataFrame.

>>> df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
>>> df
     A  B
0    1  3
1    2  4
>>> df.columns
Index(['A', 'B'], dtype='object')
dtypes

Return the dtypes in the DataFrame.

empty

Indicator whether Series/DataFrame is empty.

flags

Get the properties associated with this pandas object.

iat

Access a single value for a row/column pair by integer position.

iloc

Purely integer-location based indexing for selection by position.

index

The index (row labels) of the DataFrame.

The index of a DataFrame is a series of labels that identify each row. The labels can be integers, strings, or any other hashable type. The index is used for label-based access and alignment, and can be accessed or modified using this attribute.

pandas.Index

The index labels of the DataFrame.

DataFrame.columns : The column labels of the DataFrame. DataFrame.to_numpy : Convert the DataFrame to a NumPy array.

>>> df = pd.DataFrame({'Name': ['Alice', 'Bob', 'Aritra'],
...                    'Age': [25, 30, 35],
...                    'Location': ['Seattle', 'New York', 'Kona']},
...                   index=([10, 20, 30]))
>>> df.index
Index([10, 20, 30], dtype='int64')

In this example, we create a DataFrame with 3 rows and 3 columns, including Name, Age, and Location information. We set the index labels to be the integers 10, 20, and 30. We then access the index attribute of the DataFrame, which returns an Index object containing the index labels.

>>> df.index = [100, 200, 300]
>>> df
    Name  Age Location
100  Alice   25  Seattle
200    Bob   30 New York
300  Aritra  35    Kona

In this example, we modify the index labels of the DataFrame by assigning a new list of labels to the index attribute. The DataFrame is then updated with the new labels, and the output shows the modified DataFrame.
