# Changing Pipe Properties

## Preamble¶

In [2]:
from plotapi import Terminus



## Introduction¶

The Terminus pipes can be modified to improve the presentation of our diagram, giving us control over the spacing and slope positions.

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

## Dataset¶

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [3]:
links = [
{"source":"England", "target":"Germany", "value": 1000},
{"source":"England", "target":"France", "value": 3000},
{"source":"England", "target":"Spain", "value": 5000},
{"source":"England", "target":"Italy", "value": 4000},
{"source":"England", "target":"Japan", "value": 800},

{"source":"Ireland", "target":"Germany", "value": 3500},
{"source":"Ireland", "target":"France", "value": 3750},
{"source":"Ireland", "target":"Spain", "value": 1750},
{"source":"Ireland", "target":"Italy", "value": 5000},
{"source":"Ireland", "target":"Japan", "value": 400},
]


We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

## Visualisation¶

There are many opportunities to customise the Terminus pipes.

• slope_start, to change the point at which the pipe starts transitioning from its source $x$ (or $y$) position to its target $x$ (or $y$) position. Whether it's $x$ or $y$ depends on whether it's a vertical Terminus diagram or not. This value must be a float between or equal to $0.0$ and $1.0$.
• slope_end, similar to the above, but for when the sope ends.
• target_spacing_ratio, to specify how much of the arrangement should be whitespace versus how much should be taken up by pipe thickness. This value must be a float between or equal to $0.0$ and $1.0$.

Let's try a few combinations.

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

In [8]:
Terminus(links, show_stats=False, slope_start=0.1, slope_end=0.9).show()

Plotapi - Terminus Diagram
In [10]:
Terminus(links, show_stats=False, slope_start=0.45, slope_end=0.55).show_png()

In [9]:
Terminus(links, show_stats=False, pipe_spacing_ratio=0.8).show_png()

# Changing Stats Properties

## Preamble¶

In [2]:
from plotapi import Terminus



## Introduction¶

The stats panel that appears in a default Terminus diagram can be adjusted or hidden entirely. This gives us even more control over the presentation of our Terminus diagram.

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

## Dataset¶

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [3]:
links = [
{"source":"England", "target":"Germany", "value": 1000},
{"source":"England", "target":"France", "value": 3000},
{"source":"England", "target":"Spain", "value": 5000},
{"source":"England", "target":"Italy", "value": 4000},
{"source":"England", "target":"Japan", "value": 800},

{"source":"Ireland", "target":"Germany", "value": 3500},
{"source":"Ireland", "target":"France", "value": 3750},
{"source":"Ireland", "target":"Spain", "value": 1750},
{"source":"Ireland", "target":"Italy", "value": 5000},
{"source":"Ireland", "target":"Japan", "value": 400},
]


We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

## Visualisation¶

There are many opportunities to customise the Terminus stats panel.

• show_stats, to show or hide the stats panel.
• stats_text_width, to adjust the width of each stats column.
• show_stats_title, to hide or show the stats titles.

Let's try a few combinations.

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

In [4]:
Terminus(links, show_stats=False).show()

In [5]:
Terminus(links, show_stats_title=False).show_png()

In [6]:
Terminus(links, stats_text_width=150).show_png()

# Changing Bar Properties

## Preamble¶

In [ ]:
from plotapi import Terminus



## Introduction¶

The bars that appear at each terminus can be modified or hidden entirely. This gives us even more control over the presentation of our Terminus diagram.

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

## Dataset¶

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [ ]:
links = [
{"source":"England", "target":"Germany", "value": 1000},
{"source":"England", "target":"France", "value": 3000},
{"source":"England", "target":"Spain", "value": 5000},
{"source":"England", "target":"Italy", "value": 4000},
{"source":"England", "target":"Japan", "value": 800},

{"source":"Ireland", "target":"Germany", "value": 3500},
{"source":"Ireland", "target":"France", "value": 3750},
{"source":"Ireland", "target":"Spain", "value": 1750},
{"source":"Ireland", "target":"Italy", "value": 5000},
{"source":"Ireland", "target":"Japan", "value": 400},
]


We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

## Visualisation¶

There are many opportunities to customise the Terminus bars.

• show_bars, to hide or show them.
• outer_bars, to place the bars inside or outside a terminus.
• bar_width, to set the maximum width of the bars.
• colored_target_bars, to enable or disable coloured target bars. By default, they are all black.

Let's try a few combinations.

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

In [3]:
Terminus(links, height=400, outer_bars=True, bar_width=150, colored_target_bars=True).show()

Plotapi - Terminus Diagram
In [4]:
Terminus(links, height=400, show_bars=False).show_png()

# Changing Pipe Colours

## Preamble¶

In [2]:
from plotapi import Terminus



## Introduction¶

The pipe_color and pipe_opacity can be changed to improve the presentation of our Terminus diagram.

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

## Dataset¶

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [3]:
links = [
{"source":"England", "target":"Germany", "value": 1000},
{"source":"England", "target":"France", "value": 3000},
{"source":"England", "target":"Spain", "value": 5000},
{"source":"England", "target":"Italy", "value": 4000},
{"source":"England", "target":"Japan", "value": 800},

{"source":"Ireland", "target":"Germany", "value": 3500},
{"source":"Ireland", "target":"France", "value": 3750},
{"source":"Ireland", "target":"Spain", "value": 1750},
{"source":"Ireland", "target":"Italy", "value": 5000},
{"source":"Ireland", "target":"Japan", "value": 400},
]


We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

## Visualisation¶

The pipe_opacity must be a float between or equal to $0.0$ and $1.0$.

The pipe_color must be a colour expressed as a string, e.g. a HEX color code.

Let's try a few combinations.

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

In [35]:
Terminus(links, pipe_color="#FFFF00", pipe_opacity=0.1).show()

Plotapi - Terminus Diagram
In [36]:
Terminus(links, pipe_color="#000000", pipe_opacity=1).show_png()

In [40]:
Terminus(links, pipe_color="cyan", pipe_opacity=0.1).show_png()

# Different Pipe Alignment

## Preamble¶

In [1]:
from plotapi import Terminus



## Introduction¶

Pipes are aligned to the top-left by default, however, changing their alignment with pipe_alignment can often significantly improve the presentation of a Terminus diagram. The pipe_alignment works regardless of the vertical or bundled settings.

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

## Dataset¶

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [2]:
links = [
{"source":"England", "target":"Germany", "value": 1000},
{"source":"England", "target":"France", "value": 3000},
{"source":"England", "target":"Spain", "value": 5000},
{"source":"England", "target":"Italy", "value": 4000},
{"source":"England", "target":"Japan", "value": 800},

{"source":"Ireland", "target":"Germany", "value": 3500},
{"source":"Ireland", "target":"France", "value": 3750},
{"source":"Ireland", "target":"Spain", "value": 1750},
{"source":"Ireland", "target":"Italy", "value": 5000},
{"source":"Ireland", "target":"Japan", "value": 400},
]


We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

## Visualisation¶

The options available for pipe_alignment are: top, bottom, justify, and camel.

Let's demonstrate pipe_alignment=camel on a vertical Terminus diagram first, and then illustrate a few different configurations as PNGs.

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

In [3]:
Terminus(links, vertical=True, width=500, height=600, pipe_alignment="camel").show()
