v0.12.7a0        released 2020-08-09

Enhancements

v0.12.6a3        released 2020-06-28

  • accept lower case column names in dataframe (i.e. 'close' is the same as 'Close') (Issue #197)

v0.12.6a2        released 2020-06-28

  • tight_layout now supports adjusting Figure borders (padding) around plot. (Issue #196)

v0.12.6a1        released 2020-06-25

  • make_mpf_style() may set y_on_right=None: prevent crash by treating None the same as False. (Issue #190)

v0.12.6a0        released 2020-06-24

Enhancements

  • make_addplot() enhancements:
    • support type= ohlc and candle (issue #168)
    • support mav kwarg
    • support y_on_right kwarg
    • support ylim kwarg
    • expand impact of width and alpha kwargs (originally affected only make_addplot(data,type='bar') plots).
      • use alpha also on scatter plots.
      • use width and alpha also on line plots (issue #185)
  • improve default line-widths algorithm
  • rename set_ylim kwarg to ylim to be consistent with ylabel kwarg.
  • deprecate set_ylim_panelB (use ylim in make_addplot() instead).

Bug fixes

  • axisoff and tight_layout should be independent of each other (issue #180)
  • fix Spyder console block/hang when not inline call mpf.plot(). (issues #151 and #183)
  • fix incorrect linestyles character for dotted (issue #186)

v0.12.5a3        released 2020-06-16

Enhancements

  • improvements to width adjustment algorithm (issue #174)
  • automatic width adjustment now also adjusts mav lines widths. (issue #171)

v0.12.5a2        released 2020-06-08

Enhancements

  • Support setting ylabel in make_addplot() (Thank you Andy Sum for coding.)
  • Add saxbelow kwarg to set_axisbelow(), defaults to True so grid lines do not show through candles, etc.

Buf Fixes

  • fix tight_layout issue #156 (tight_layout not affecting Figure Title; Thank you Markus Schulze for pointing this out.)

v0.12.5a1        released 2020-06-07

Enhancements

  • Subplots: Create up to 10 "panels"
    • Can modify relative sizes of panels
    • Can modify which is "main" panel
    • Can modify which is "volume" panel
    • addplot can plot to any panel
    • MACD example
  • support bar charts in make_addplot (type= 'line', 'scatter', or 'bar')
  • make_addplot scatter now supports sequence of markers and sequence of colors
    (Thank you Elan Ernest for posting the sequence of markers solution here)
  • ability to custom format date/time labels ( datetime_format=) (Thank you Cam McLean)
  • ability to rotate date/time labels (xrotation=)
  • ability to turn axis off (axisoff=True) (Thank you Will Whitty for testing, code review, and contributing code changes)
  • support tight_layout=True
  • support fill_between=
  • new algorithm for adjustment of candle widths, line widths, volume widths, ohlc tick widths default change (Thank you Charles for your help).
    • ability to scale the algorithm (up or down)
    • ability to override the algorithm (i.e. set width and linewidth of volume bars, candles, ohlc bars. (iss num 81))
  • close plot when not needed to stay open default change
    • fixes "20 open plots" warning
    • removed code to close plots from regression tests: no longer needed
  • support NaNs in data to indicate missing data (also fix bug related to min/max and mav when NaNs in data) default change (Thank you Charles for your help)
    • allows display low liquidity
    • remove support for -1 meaning missing data. -1 is now considered valid data.
  • Travis check to ensure each Pull Request has a new version (Thank you Aaron Soellinger)
  • remove rcParams context: modifications made by mplfinance are now availabile after calling mplfinance. default change

Bug Fixes

  • fix bug displaying a single candle
  • fix bug "StatisticsError" when only a single data point
  • fix poor choice of default color for type=line chart default change
