matplotlib plt.bar() function wrong signature? Version? about covid-19-analysis

I am using 3.1.1.

I have 3.2.1 and your code does not work. I am surprised that it allowed you to put Timestamp in the X axis. pyplot.bar does not allow this.

Also, the named parameters did not work, I had to remove them and l use positional parameters because the new implementation of pyplot.bar is like the following:

def bar(left, height, width=0.8, bottom=None, hold=None, data=None, **kwargs):

You can notice that there is no x, it was replaced by left

This code works for me:
plt.bar(dates.values, cases, color='blue', edgecolor='k')

I got inspired by your code and I created a code for Canada. Although it is substantially changed I will credit you for the initial code in the header. Thanks.

I hope to post it soon on github.com and I hope to add some analysis and predictions based on different scenarios

I suggest trying something like the code bleow that beside making it version agnostic will also simply code repetitions in your ranking method

def plot_bar(pos, cases, dt, color, title):
            labels = [val[1] for val in cases]
            x = np.arange(len(labels))  # the label locations
            axs[pos].bar(x, [val[0] for val in cases],
                       color=color, edgecolor='k')
            axs[pos].set_title("{} on {}".format(title, str(dt)),
                             fontsize=15)

            axs[pos].set_xticklabels(labels)

then call in the code like this

    ```

_, axs = plt.subplots(2, 2, figsize=(15, 9))
axs = axs.ravel()
plot_bar(0, sorted_cases, d, 'blue', "Total cases")
plot_bar(1, sorted_deaths, d, 'red', "Total deaths")
plot_bar(2, sorted_newcases, d, 'yellow', "New cases")
plot_bar(3, sorted_newdeaths, d, 'orange', "New deaths")
