Should we make a harmonize module?

5

We are at the moment beginning to pick up more use of [`aneris`](https://github.com/iiasa/aneris) to do harmonization at various stages of analysis. When I first wrote it, I had a specific...

Filter breaks when columns contain mixtures of str and int/float

2

Filter can get confused when being used on a column that contains a mixture of both strings and numbers. Oddly it doesn't have a problem if the value being asked...

Test `test_adjusting_logger_level` incompatible with pytest v6.0

6

The behaviour of the logger in `test_adjusting_logger_level` is incompatible with (at least) `pytest` v6.0.0 and pytest v6.0.1. Per #421, the version of pytest is pinned to an earlier version. This...

The current implementation of `swap_time_for_year()` only works if the years in the `time` column are unique. For convenience of use with the openENTRANCE data format, this would be helpful to...

`as_pandas()` returns bigger-than-necessary dataframes

1

When the function `line_plot()` calls `as_pandas()` to retrieve the joined data+meta dataframe and then plots two metadata columns, it paints each marker once per timestep (because the rows in the...

`map_regions()` to `downscale_regions()`

2

With `aggregate_regions()` doing the work to upscale (many-to-one) regional data, `map_regions()` should be deprecated and a new `downscale_regions()` should be added. The function signature should look something like: ``` def...

Calling query method with wrong parameter names (e.g. `regions` instead of `region`) silently leads to retrieving all regions data: ``` conn = pyam.iiasa.Connection(db, creds=('user', 'password')) data = conn.query(scenario=valid_scenarios, variables=variable_list, regions=region_list)...

Integration with ixmp - function name?

3

An IamDataFrame can already be initialised directly from an ixmp.Scenario (via the ixmp-Python-API, see [here](https://github.com/IAMconsortium/pyam/blob/ef2f69aba9cebe0c0d953fdc55debf0d44e66861/pyam/read_ixmp.py#L8)). Now, I'm thinking about adding a function in pyam to save an `IamDataFrame` to an...

Some stack_plot calls give an IndexError.

3

Even with `matplotlib=3.0.2` (as suggested in #281), I am getting `IndexError: single positional indexer is out-of-bounds` by calling `stack_plot()`. But it doesn't apply to all `stack_plot` calls. I haven't identified...
