Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.3.1] - 2019-11-12

Changed

  • Fixed plotting of zones

[0.3.0] - 2019-11-12

Added

  • Add boolean to switch to IP units
  • Add new predefined style "ashrae_ip" in IP units
  • Add pyproject.toml file and use poetry to manage the package and travis CI

Changed

  • Rely on psychrolib for psychrometric equations
  • Reformat code to adapt to current standards (black and stricter flake8 lint checks)
  • Refactor chart.py into multiple modules:
    • Move PsychroCurve(s) classes definitions to separate module
    • Rename equations to .chartdata and move there all logic for curve data generation
  • Adapt tests and do some code cleaning
  • Redo internal units for pressure (from kPa to Pa) and enthalpy (from KJ/kg to J/kg) to use IP units
  • Adapt plots to use labels, ticks, etc as function of selected unit system.
  • Use numpy instead of lists and vectorize psychrometric operations

Removed

  • Own collection of psychrometric equations

[< 0.2.7] - Old versions changelog

  • v0.1.0: Initial version.
  • v0.1.1: Minor plotting fixes, set axis position, define P with altitude_m or pressure_kpa, reuse plot removing annotations (chart.remove_annotations). Axes as internal prop, lazy plotting, save to disk helper (chart.save).
  • v0.1.2: Add agg module to set that matplotlib backend.
  • v0.1.3: Add custom params for plotting styles, option to exclude first and last tick (constant_{humid/temp}_label_include_limits).
  • v0.1.4: Customize labels and its locations for families of psychrometric curves.
  • v0.1.5: Add Arrows, compatibility with the Home Assistant component psychrometrics.
  • v0.1.6: Some cleaning, better typing, flake8, added tox.ini.
  • v0.1.7: Methods to clean the plot (.close_fig()) and to remove the legend (.remove_legend()).
  • v0.1.8: Memleak with savefig.
  • v0.1.10: Fix plot limits, do not use pyplot, axes are not optional.
  • v0.1.11: Add optional Axes as argument for PsychroChart.plot.
  • v0.1.12: Add empiric equation for wet bulb temperature (@ZhukovGreen contribution).
  • v0.1.13: Add convex hull option for overlay points.
  • v0.2.0: Hide output in verbose mode, better convex hull zones syntax, stable.
  • v0.2.1: Make scipy an optional requirement (it's only used for the ConvexHull zone).
  • v0.2.2: Fix initial conditions for iteration solvers
  • v0.2.3: Handle ConvexHull exception, overlay of series of points.
  • v0.2.4: Set ASHRAE formulation for saturation_pressure_water_vapor as default. Minimal adjustments to iteration solvers for enthalpy and specific volume.
  • v0.2.5: Fix coefficient in ASHRAE formulation for dew_point_temperature.
  • v0.2.6: Add labels for connectors in chart legend (@@zhang-shen contribution).
