将列标签添加到条形图 (Python-matplotlib)

Question

I have a list of scores:

sincerity_scores=[[0.7386426068589986, 0.03521168088827334, 0.17283997838902623, 0.17978091813696798, 0.46179609926078796, 0.03232785417651009]

and I want to obtain a bar plot out of it.

I created the barplot with:

x=np.arange(6)

fig=plt.figure()
ax=fig.add_axes([0,0,1,1])
ax.bar(x, sincerity_scores)
ax.set_xticklabels(labels=["CocaCola", "Appletiser", "PepsiMax", "DrPepper", "MountainDew", "Welchs"])
plt.show()

but what I get is:

while I would like the lables of the colums follow the sequence i indicated with as.set_xticklabels. How to do it? Moreover, I would like to set a different colour. Is it possible?

Answer 1

change x to the list of your labels.

sincerity_scores=[0.7386426068589986, 0.03521168088827334, 0.17283997838902623, 0.17978091813696798, 0.46179609926078796, 0.03232785417651009]
x=["CocaCola", "Appletiser", "PepsiMax", "DrPepper", "MountainDew", "Welchs"]

fig=plt.figure()
ax=fig.add_axes([0,0,1,1])
ax.bar(x, sincerity_scores)
plt.show()

This results in this graph:

color can be set using the color argument in ax.bar . like so

ax.bar(x, sincerity_scores, color='k')

resulting in all bars being black.

You can change 'k' for any matplotlib color or any hexcolor code you desire. If you want each bar to have a different color feed a list of codes to color with the same length as you have bars.
