Hi, it's now possible to install via conda install -c conda-forge bar_chart_race see this. If you want could update README.md or I could make a PR.

It would be helpful to include the license file in the source distribution. I've seen this done by using a MANIFEST.in file, but there are other mechanisms as well.

Also as a side note, the meta data in the setup.py says this package uses a BSD license, but the license says MIT: https://github.com/dexplo/bar_chart_race/blob/master/setup.py#L23

Hi, I get this issue when I load the example script

I'm using python 3.8.5 and matplotlib 3.3.1

The text is shaking in the second bar with the following parameters. Will try to replicate the example with non-prop data.

bar_textposition='inside',
bar_texttemplate = 'K${x:,.1f}',
n_bars = 10,
bar_size = 0.9,
period_length = 250,
end_period_pause = 750,

Is that possible to pause the animation for 1 or 2 secs after every row of data is displayed?

It will be nice to grab the attention of the viewer to one or more of the categories. For example, you can give the option to place a box only around the chosen categories or choose a highlight color that contrasts with others.

This is working fine:
bcr_html = bcr.bar_chart_race(df=df, filename=None)
display(HTML(bcr_html))

However, tried the featured example on Github and got two errors. Error 1:

[1] dark12 not found in cmap. Changed that to Dark2. (working)

[2} AttributeError: 'Rectangle' object has no property 'fixed_order'

Not clear how to fix the second error

How to change the column color when the value greate than a specify value?

When I try the example 'covid19' in python3.6.6 ,the result somehow went wrong?

After upgrading to version 0.2.0 the padding below the x-axis seems to have reduced.
What is the option to increase it back again ?

I have been trying to modify the parameters such as the bar size and such, but those bars are still stack on top of each other, is there any solutions for this? Thanks

Hi there!

I have a dataframe that the rate of changes is slow. So, I need to see how it changes through two decimals. Is there any way to change the format of the texts on the bars to float with specific decimals?

In the Github page, I've found:

bar_texttemplate='{x:,.0f}'

But I get keyword argument error since I guess it is removed. I cannot find the keyword in the documentation page.

Do you have any ideas how to do this?

When sorting by date, the dates like this on March 2, 2019 (2019-3-2)will be between March 19, 2019(2019-3-19) and March 20, 2019(2019-3-20).

I checked that there is already a closed issue about this and that it is in the works. Is there any update? I want to show an image (circular if possible) for each category or bar instead of text. For example, for the covid-19 dataset, I would like to be able to show country flags instead of the name (or maybe both would also be useful).

If I wanted to make this addition myself, where in the code would be the best place to start working on? Is this a feature of matplotlib?

Hi,

is there a way to change the number format in X-axis?, in my country the comma is used as decimal separator, I tried to fix this with the import of locale library, but the issue continues...

When trying to change the background color by passing the matplotlib fig, the background inside the axes is changed but outside isn't.

Hi,

Is there way to show float numbers that contains big exponential. Currently, its showing plain number which is too big to fit into the picture

Hello, I have been trying this library to animate data I collected about my puppies while they were growing. However, I have a problem where many of the bars overlap with each other.

The dataset has 9 different dogs, and about 200 data points per dog (there are many NaN values in between). Do you have any suggestions about what could be the issue?

Exception: You do not have ffmpeg installed on your machine. Download
                            ffmpeg from here: https://www.ffmpeg.org/download.html.

I'm trying to run the example code as shown in the README.md, however, I'm getting the above error.

I am on Windows, and have already installed ffmpeg, and included it in my Path variables.

Is there anyway to run without ffmpeg?

Hi. Thank you for developing it.
I need to show percentages next to the bars but it only showed integers rather than floats. Can you add an option to change the format?
Also, the ticks have no shading color and they will overlie each other when they meet and people can see neither. Can you add shading color so people can see at least one of them? Thank you.

Hi Ted,

Very good API ... Thanks a lot !!

I would request that you permit X-Axis to include negative values as well. If you were to include then it follows that the "fixed_min" will be good to have just like you have "fixed_max".

The use case where say I'm plotting return of a group of stocks, and some of them have negative return that I'd like to plot. (In case of Covid deaths and Home Runs it's all expressed as positive X-Axis values, however there are instances of negatives as well.) Another use case could be where we're plotting the Average Temperatures of Chicago, Houston, San Francisco, Los Angeles etc. recorded on Jan1, Feb 2, Mar 1, etc.

Thanks.

Hello,

I am trying to plot the bottom 10 categories from my dataset. I am changing the sort attribute to 'asc' and then it just plots the top 10 categories in ascending order,
let's say we have 5 categories e.g.
Category | Value
category 1| 1
category 2| 2
category 3| 3
category 4| 4
category 5| 5

and I want to plot (animate) the bottom 3. If I change the sort to attribute to asc then the plot is like this:
category 3| 3
category 4| 4
category 5| 5

but it should have been
category 1| 1
category 2| 2
category 3| 3

Do you have any idea how to fix this?

Thanks a lot,
Andreas

It looks like it isn't possible to format the Bar Labels while it's sometimes necessary to display float.

The package is super, thanks!
I suggest implementing a feature to only show entries above a certain threshold in the bar chart race. To explain what I mean, let's consider the COVID-19 pandemic. Let's assume that I set the threshold to 0, i.e. only show countries with more that 0 COVID-19 cases/deaths. In the beginning, the bar chart race would only include China, but as the virus is spreading more and more countries would "enter" the bar chart race once the threshold is met. This would be a super useful feature in cases where many entries have zero (or low) starting values.

This could be combined with an "nminbars" parameter, which would overrule the threshold value, so that one could force minimum, say, 5 entries in the race, but more would be added once the threshold is met (until the nmaxbars is reached).

Some of the values of bar graph are wrong compared with the source data. How to correct them?

In my use case, I want to use custom colors per bar.

So, altogether I wanna use only two colors for my bars.

Tried to use the following in my chart which has 14 bars,
cmap = (["green"] * 7) + (["red"] * 7)

Great! this assigns the colors to bars in Order too!

First of all, thanks for putting this together, it's a really easy-to-use and effective way to produce a good-looking bar chart race.

Is it possible to make the location of the index when use_index=True adjustable? For the video I created the index (in this case the year) overlaps with the bottom bars.

This is the code I used in Jupyter. The full Notebook is here

    df=income_new,
    filename='income.mp4',
    period_length=250,
    title='GDP per capita (in 2011 USD)',
    n_bars=10)

This is just a suggestion for an improvement. If there were an argument that could be passed with a few different options (eg right, centre, left, upper_right, lower_right) that would allow the user to avoid this issue.

Thanks again for your work on this package.

Hello all, can anyone tell me how to save the race in plotly, like the second graph on https://www.dexplo.org/bar_chart_race/ with title "COVID-19 Bar Chart Race with Plotly" and Play and Pause buttons. For me already works the bar chart race but exporting to mp4, gif or html.

Best regards.

Package Version

Hello, I have some problem :)

bcr.bar_chart_race( df=df, orientation='h', sort='desc', n_bars=10, fixed_order=False, fixed_max=True, steps_per_period=4, label_bars=True, bar_size=.55, filter_column_colors=False, figsize=(5,4))

This is my data.

Bar was overlapping and just hold the position
I want to go down when bar number is lower than others.
Thanks.

Nice package! One suggestion I have is to have a preview keyword that either only does the head of the pandas dataframe or have it skip half the frames because after taking a while to export the gif, I realized the labels were all crammed and the data doesn't really start until a later date (i.e. the bars were all at 0).

Hey Guys!

First of all, thank you so much for your effort with this great tool!

The issue is basically described in the subject. The y-axis labels of all my plots are shaking if any label has a different number of strings and changes the order while racing.

For instance, I have 40 data and I choose the top 10. In the beginning, the longest string is "UC Browser" in the screenshot. Therefore, the y-label space on the left-hand side uses "UC Browser" to calculate the space. However, after a few seconds, the "360 Safe Browser" is in the top 10. But the string length is longer than the previous one. I guess it causes the different sizes of the plot and the width of the x-axis, and it will shake after it generates the animation. Please kindly refer to the below image.

Do you have any idea how to fix the position of the y-axis or the width of the x-axis? Or can we get the longest string number throughout all data and use it to set up space on the left-hand side even that label is not in the top 10 rankings?

Feel free to let me know if you have any suggestions. I truly appreciate your assistance.

First of all thank you for this contribution! We needed this on python too.

Do you mind to add a requirement.txt in your main?

# requirement.txt
pandas
numpy
matplotlib

I'm now writing a conda package for this library but in case you change some dependencies have them in a file will be easier to manage.

Is there any guide about how to use this?
For example, If I want show 1 decimal place, how should I do?

Hello,

I am trying to run the example code provided.

import bar_chart_race as bcr
df = bcr.load_dataset('covid19_tutorial')
bcr.bar_chart_race(
        df=df, 
        filename='../docs/images/covid19_horiz.gif', 
        orientation='h', 
        sort='desc', 
        n_bars=8, 
        fixed_order=False, 
        fixed_max=True, 
        steps_per_period=20, 
        period_length=500, 
        end_period_pause=0,
        interpolate_period=False, 
        period_label={'x': .98, 'y': .3, 'ha': 'right', 'va': 'center'}, 
        period_template='%B %d, %Y', 
        period_summary_func=lambda v, r: {'x': .98, 'y': .2, 
                                          's': f'Total deaths: {v.sum():,.0f}', 
                                          'ha': 'right', 'size': 11}, 
        perpendicular_bar_func='median', 
        colors='dark12', 
        title='COVID-19 Deaths by Country', 
        bar_size=.95, 
        bar_textposition='inside',
        bar_texttemplate='{x:,.0f}', 
        bar_label_font=7, 
        tick_label_font=7, 
        tick_template='{x:,.0f}',
        shared_fontdict=None, 
        scale='linear', 
        fig=None, 
        writer=None, 
        bar_kwargs={'alpha': .7},
        fig_kwargs={'figsize': (6, 3.5), 'dpi': 144},
        filter_column_colors=False) 

After installing everything (including ffmpeg) I always get these 2 errors:

UserWarning: FixedFormatter should only be used together with FixedLocator
ax.set_yticklabels(self.df_values.columns)

UserWarning: FixedFormatter should only be used together with FixedLocator
ax.set_xticklabels([max_val] * len(ax.get_xticks()))

Is there any way around this? I find it a bit weird that the example code is not working properly.

Thanks in advance!

Great and lovely Library! Just a reminder that the version installs via pip seems to be outdated. Solved itself when I installed "python -m pip install git+https://github.com/dexplo/bar_chart_race"

The issue was that: argument end_period_pause was not present before that
