QUESTION
Surprisingly little info out there regarding python and the pyalluvial package. I'm hoping to combine stacked bars and a corresponding alluvial in the same figure.
Using below, I have three unique groups, which is outlined in Group
. I want to display the proportion of each Group
for each unique Point
. I have the data formatted this way as I need three separate stacked bar charts for each Point
.
So overall (Ove
) highlight the overall proportion taken from all three Points
. Group 1
makes up 70%, Group 2
makes up 20%, Group 3
makes up 10%. But the proportion of each group changes at different intervals Points
. I'm hoping to show this like a standard stacked bar chart, but add the alluvial over the top.
ANSWER
Answered 2021-Aug-05 at 13:54As correctly pointed out by @darthbaba, pyalluvial
expects the dataframe format to consist of frequencies matching different variable-type combinations. To give you an example of a valid input, each Point
in each Group
has been labelled as present (1
) or absent (0
):

Install pyalluvial
You can use pyalluvial like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
