Restructure

Bring the structure closer to an mpl module

To do

Testing

• [x] Testing data set suitable to test layouts and styling
• [x] Include pandas df in test cases

Input and modification

• [x] Allow membership lists
• [x] Set up diagram, column and block selection {by indexing only?)
• [x] Implement Tags
• [x] Allow _dynamiccommunities to be passed to membership lists init
• [x] Panda compatible
• [ ] All modifications are done over Alluvial instance (single interface) no possibility to retrieve SubDs, Tags, Blocks, or Flows. This is to make sure to keep track of what needs updating (layout and styling)

Layout

• [x] Possible layouts are 'top', 'bottom', 'centered' and 'optimized'. Only 'optimized' takes vertical flow distances into account.

• [x] Difference between 'top' and 'bottom' is y-axis direction. Not ideal, as this complicates having column specific layouts.

• [ ] Allow to position a column (y-offset) such that the total vertical displacement of attached flows is (approx.) minimized.

• [ ] Allow block swapping within column (more generally, pushing all blocks in a list of blocks back one index an put last at index 0).

• [x] Automatically set the x&y limits.

• [x] Sorting flows attached to a single block based on:

  1. vertical center-displacement of attached blocks
  2. vertical attach-location displacement of the flow

• [ ] Implementation of 'optimized' layout algorithm

  • fix existing
  • potentially improve

• [x] make the y-axis invisible by default

Styling

• [x] Set up default styling (flow with alpha 0.7?)

• [x] Assert priority hierarchy for styling arguments: Proxies > Tags > SubDiagrams > Alluvial

• [ ] Flows colors can handle 'source', 'target', 'interpolate' and 'migration':

  • [ ] source & target inherit color from respective block.
  • [ ] interpolate creates horizontal linear gradient from source color to target color
  • [ ] migration: allow to specify a color in case source and target block do not have the same tags (identical tag list).

• [x] cmaps for blocks with common tag

• [x] cmaps for blocks in SubDiagram

Examples to specify

Needs rc 3.4.0 for cbook.narmalize_kwargs for the tests to pass...
