BarChart implementation for bar chart races

Parameters

BaseChart (BaseChart) – Base class shared by all chart types

Returns

Instance of BarChart allowing for inclusion in subplot charts or animating with .save()

Return type

BarChart

Methods

BarChartRace.__init__(df, …)	Initialize self.
BarChartRace.anim_func(i)	Animation function, removes all bars and updates legend/period annotation.
BarChartRace.apply_style(ax)	Apply styling to axes with spines and grid, can be overridden
BarChartRace.calculate_new_figsize(real_fig)	Calculate figure size to allow for labels, etc
BarChartRace.calculate_ranks(df)	Calculate expanded dataframe to match length of animation
BarChartRace.clearing()	Function to remove all existing lines, collections, etc at the start of the animation AND after a save.
BarChartRace.create_figure()	Create Bar chart figure
BarChartRace.get_colors(cmap)	Get array of colours from BaseChart.get_colors and shorten to number of bars
BarChartRace.get_data_cols(df)	Get list of columns containing plottable numeric data to plot
BarChartRace.get_frames()	Method for determining range of frames to animate.
BarChartRace.get_html5_video()	Convert the animation to an HTML5 <video> tag.
BarChartRace.get_interpolated_df(df, …)	Get interpolated dataframe to span total animation
BarChartRace.get_label_position()	Get label position for period annotation
BarChartRace.get_period_label(period_label)	Parameters for period annotation on charts, dict will be passed to kwargs in matplotlib.ax.text()
BarChartRace.get_single_color(color_string)	Get single RBGA value from string
BarChartRace.init_func()	Initialization function for animation
BarChartRace.make_animation(frames, init_func)	Method for creating animation
BarChartRace.plot_bars(i)	Plot bars in bar chart race on axes
BarChartRace.rename_data_columns(df)	Converts all column names to string
BarChartRace.save(filename)	Save method for FuncAnimation.
BarChartRace.set_x_y_limits(df, i, ax)	Set axis limits for both x and y of passed axes object
BarChartRace.setup_progress_bar()	Create an instance of alive-progress bar in manual mode
BarChartRace.show_period(i)	Show period label on plot
BarChartRace.update_progress_bar()	Update TQDM instance by 1
BarChartRace.validate_params()	Validate parameters provided to chart instance
