Python matplotlib bar graph color

Question

I'm trying to display some data in bar graph using xticks. The code below displays my bars in different colors. My question is how do I make the whole graph in one color? Thanks in advance.

import matplotlib.pyplot as plt

data = (5)
data_2 = (6)

plt.bar(1, data)
plt.bar(2, data_2)

plt.xticks([1,2], ('Hello', 'World'))

plt.show()

Answer 1

Here is how:

import matplotlib.pyplot as plt

data = (5)
data_2 = (6)

plt.bar([1,2], [data,data_2])

plt.xticks([1,2], ('Tom', 'Dick'))

plt.show()

---

Or add color keyword argument:

import matplotlib.pyplot as plt

data = (5)
data_2 = (6)
color = 'red'
plt.bar(1, data, color=color)
plt.bar(2, data_2, color=color)

plt.xticks([1,2], ('Tom', 'Dick'))

plt.show()

Output:

Answer 2

I think that there is an easier way to obtain the same color for all bars.

import matplotlib.pyplot as plt

x = [1,2]
x_ticks = ['Tom', 'Dick']
y = [5,6]
plt.bar(x, y)
plt.xticks(x, x_ticks);

In case you want to use pandas

import pandas as pd

df = pd.DataFrame({'x': [1,2],
                   'y': [5, 6],
                   'name': ['Tom', 'Dick']})

ax = df.plot(x='x', y='y', kind='bar')
ax.set_xticks(df.index)
ax.set_xticklabels(df["name"], rotation=0);

or even easier

df.plot(x='name', y='y', kind='bar', rot=0);
