Adjusting Popup Width

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

Depending on the visualisation, expanding or restricting the width of the popup may be necessary.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)
Out[3]:
Action Adventure Comedy Drama Fantasy Thriller
Action 0 5 6 4 7 4
Adventure 5 0 5 4 6 5
Comedy 6 5 0 4 5 5
Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Thriller 4 5 5 5 4 0

Visualisation

We can modify the popup width with the popup_width parameter.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to a HTML file with .to_html() instead. More on the different output methods later!

Be sure to interact with the visualisation to see what the default settings can do!

In [8]:
Chord(matrix, names, colors="set3", popup_width=100).show()

Multi-line Label Wrapping

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

Plotapi Chord labels wrap by default - this can be disabled if required.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Exciting Action", "Fun Adventure", "Hilarious Comedy", "Drama", "Fantasy", "Chilling Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)
Out[3]:
Exciting Action Fun Adventure Hilarious Comedy Drama Fantasy Chilling Thriller

Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Chilling Thriller 4 5 5 5 4 0

Visualisation

Label wrapping is controlled with by the wrap_labels parameter which is True by default.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to a HTML file with .to_html() instead. More on the different output methods later!

Be sure to interact with the visualisation to see what the default settings can do!

In [6]:

Enabling Curved Labels

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

In some cases, curved labels may improve the look of our visualisation. They are not enabled by default because they are not suitable for all datasets - especially those which result in many small segments.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)

Comedy 6 5 0 4 5 5
Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Thriller 4 5 5 5 4 0

Visualisation

To enable curved labels, we set curved_labels=True

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to a HTML file with .to_html() instead. More on the different output methods later!

Be sure to interact with the visualisation to see what the default settings can do!

Changing the Label Colour

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

We can change the colour of the labels to something more suitable for our visualisation if needed.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],

Adjusting the Radius scales

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

We can adjust the inner and outer radius scale of our Chord diagram if it suites our desired design. This will change the thickness of the segmets.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],

Adjusting Layout Properties

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

Let's take a look at some parameters that control the layout of our diagram.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)
Out[3]:
Action Adventure Comedy Drama Fantasy Thriller
Action 0 5 6 4 7 4
Adventure 5 0 5 4 6 5
Comedy 6 5 0 4 5 5
Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Thriller 4 5 5 5 4 0

Visualisation

We can modify the width, margin, and rotation of our diagram.

The width parameter will also set the height, as the Plotapi Chord maintains a $1:1$ ratio.

The margin parameter expects a single float to imply an equal margin of that size.

The rotate paramater will rotate the Chord diagram around its center.

By default a Chord diagram is centered, but this can be disabled with center=False.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to a HTML file with .to_html() instead. More on the different output methods later!

Be sure to interact with the visualisation to see what the default settings can do!

In [4]:
Chord(matrix, names, width=500, margin=100, rotate=-30).show()

Adjusting the Font Size

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

We can adjust the font-size used for our labels.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)
Out[3]:
Action Adventure Comedy Drama Fantasy Thriller
Action 0 5 6 4 7 4
Adventure 5 0 5 4 6 5
Comedy 6 5 0 4 5 5
Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Thriller 4 5 5 5 4 0

Visualisation

The font size is controlled by two parameters. These set the font-size for two views, font-size-large (@media min-width: 600px), otherwise font-size. Setting a large font-size may require adjustment of the margin parameter to avoid text-clipping.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to a HTML file with .to_html() instead. More on the different output methods later!

Be sure to interact with the visualisation to see what the default settings can do!

Adjusting Segment Padding

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

Adjusting padding may not sound exciting, but in this case, it can have some interesting effects.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
