3.1.0

Added

• Support for Python 3.14.
• Introduce constants.UNICODE_Y_AXIS, constants.UNICODE_Y_AXIS_LEFT, and constants.UNICODE_Y_AXIS_RIGHT, constants to control the Unicode character printed next to prices on the Y-axis (defaults to │, ┤, and ├, respectively).
• New color: gray (which is an alias to the misspelled "grey").
• New utils.round_price() function to either round down, or up, the price on the Y-axis. Previously, it was a private method of the YAxis class.
• 100% coverage with tests!

Changed

• Fixed CandleSet.min_volume being always 0.0 (commit 6975d7f).
• Those functions now also accept a pathlib.Path argument, in addition to the original str: utils.parse_candles_from_csv(), and utils.parse_candles_from_json().
• Updated the pypa/gh-action-pypi-publish GitHub action from master to release/v1.

2.7.0

Added

• Support for Python 3.12
• CI to run unit tests
• Tests for the CLI entry point

Changed

• Set the default chart name to a blank string in the CLI (fixes #9)
• Use shutil.get_terminal_size() instead of os.get_terminal_size() to be able to run tests without hitting OSError: [Errno 25] Inappropriate ioctl for device
• Fix Mypy error PEP 484 prohibits implicit Optional

2.6.0

Added

• Allow to use a custom class for the chart rendering via the Chart(..., renderer_cls=MyClass) keyword argument (see examples/custom-renderer-class.py for inspiration)
• The module is is now PEP 561 compatible, and tested with mypy

Changed

2.5.1

Changed

• Allow to pass a blank color to color(), it will return the text unchanged
• Refactored price hightlights, it should now highlight price that would be hidden by a slightly upper value (like 1.025 being hidden because that exact price is not available, but it is surrounded by 1.02, and 1.03, then it will take the place of 1.02)
• Better-looking Y-axis style (when on the left-side: PRICE │― → PRICE ┤, and on the right-side: │― PRICE → ├ PRICE)

2.5.0

Added

• Capability to round prices on the Y-axis via Y_AXIS_ROUND_DIR (either down [default], or up), and Y_AXIS_ROUND_MULTIPLIER (0.0 by default, set something like 1 / 0.01 to round price to 2 decimals), constants

Changed

• Improve rendering performances by ~60%

2.4.0

Added

• Capability to highlight values on the Y-axis using chart.set_highlight()
• New colors: blue, cyan, grey, magenta, and white

2.3.0

Added

• Capability to display graduations on the right side by setting the constants.Y_AXIS_ON_THE_RIGHT to True

Changed

• Fixed a zero division error when no candle volume is set
• Chart title is now hidden if it is an empty string

2.2.1

Added

• constants.PRECISION, and constants.PRECISION_SMALL to control the number of decimals to keep when formatting numbers with fnum() (defaults to 2, and 4, respectively)
• constants.MIN_DIFF_THRESHOLD, and constants.MAX_DIFF_THRESHOLD to control candle top, and bottom, thickness fnum() (defaults to 0.25, and 0.75, respectively)

Changed

• Fixed formatting of 1.0 number within fnum()
• Fixed imports using isort

2.2.0

Added

• Candle.__eq__() to allow comparing candles
• Introduced constants.Y_AXIS_SPACING to give control on Y-axis spacing between graduations (defaults to 4, reduce to display more graduations, and set a higher number to display less graduations)

Changed

• Constant changes are now taken into account in real-time, it allowes to tweak the chart appearence after having imported the module
• Always show the volume pane when it is enabled
