Change Log

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

0.2.4 - 2020-11-078

  • Fixed an issue in which certain charts were removing the period_summary_func label from the chart (issue #20)
  • Refactoring changes and code formatting
  • Documentation updates to direct link to images as to not break on external websites (eg, PyPI)

0.2.3 - 2020-10-18

  • Fixed an ongoing problem with animate_multiple_plots when re-using a line or scatter chart. Corresponding subplots would show a static figure from a previous single animation.
  • Fixed fig= for single animations not being passed properly as a custom figure.
  • Several performance improvements to speed up loops in animations.
  • Fixed a problem with line and scatter plots being chopped off near the vertical limit values.
  • Added a colorbar with bubble plots when a Pandas df column is passed as a colour. Currently only for individual animations.
  • Added options for bubble plots above to control the colorbar scale limits with vmin & vmax. If None, then they are automatically calculated.
  • Added option add_legend= for line and scatter animations for single & multiple plots. Default is True.
  • Added the option enable_progress_bar= to animate_multiple_plots. Default is False.
  • Improved the ability to re-use figures & axes in a notebook for multiple plots. Occasionally, these used to carry over old frames into a new animation.
  • Made animate_multiple_plots to create a Figure() instance instead of a figure() one. Note that matplotlib can take twice as long to generate animations with the latter instance type. Not clear why.
  • Added a new folder ./examples/test_notebooks/ for future collaborators to add new notebooks.
  • Removed the limitation for the interpolation (interpolate_period=) only to work with a DateTime index. It should now work with any numeric df index.

0.2.2 - 2020-06-04

  • Additional error catching with warnings for modules not being installed
  • Add both attrs and pillow as dependencies, so users can install with pip and have it just work

0.2.1 - 2020-06-02

  • Custom figures now supported in animate_multiple_plots
  • Writing to GIF in memory with PIL now supported, no external dependencies for gifs!

[0.2.0]

  • Changing version format MAJOR.MINOR.PATCH
  • Introduces support for geospatial data with geopandas
    • Introduces support for basemap on geospatial datasets with contextily

[2020.05.15]

  • Officially changing to version format with YYYY.MM.VERSION
  • Hotfix for anaconda environment throwing an error:
    • ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

[0.1.14] - 2020-05-23

  • Progress bars (thanks to tqdm can now be enabled with `df.plot_animated(enable_progress_bar=True)
  • Writer can now be specified with df.plot_animated(writer="imagemagick")
    • Pillow is now explicitly unsupported, see relevant issue here #5

[0.1.13] - 2020-05-21

  • New chart type introduced: Bubble Charts, to be used with MultiIndexed DataFrames.

    • Bubble charts support x & y axis by data inside MultiIndex (x_data_label & y_data_label)
    • Bubble charts support size & color optionally by data inside DataFrame (size_data_label & color_data_label)

  • New chart type introduced: Scatter Chart

  • New chart type introduced: Bar Chart, create animated bar charts with time as the x-axis

  • QOL improvements for warnings & errors

  • Line charts now support filling underneath to mimic an area chart df.plot_animated(kind="line",fill_under_line_color="red")

  • Line charts now support event labelling with perpendicular bars

    df.plot_animated(
            kind='line',
            label_events={
                'Ruby Princess Disembark':datetime.strptime("19/03/2020", "%d/%m/%Y"),
                'Lockdown':datetime.strptime("31/03/2020", "%d/%m/%Y")
            },
        )

[0.1.12] - 2020-05-10

  • fixed_max optional for all chart types
  • fixed_max amended to work with multiple plots

[0.1.11] - 2020-05-09

  • period_summary_func provided for charts to display overall period calculations on plot
  • Bar chart functionality extended
    • fixed_order can be used to disable bars moving on bar chart
    • fixed_max set limits of axis on charts to be total maximum of dataframe rather than dynamic
    • perpendicular_bar_func Plot perpendicular black bar on plot to demonstrate different stats, eg, max, min, median, etc. Use with Series.agg()

[0.1.10] - 2020-05-08

  • Complete overhaul of backend with _base_plot.py, refactored all arguments
  • README & Examples generated from README.ipynb, converted with nbconvert
