How to plot confidence interval in Python?

Question

I recently started to use Python and I can\'t understand how to plot a confidence interval for a given datum (or set of data). I already have a function that computes, given

Answer 1

Let's assume that we have three categories and lower and upper bounds of confidence intervals of a certain estimator across these three categories:

data_dict = {}
data_dict['category'] = ['category 1','category 2','category 3']
data_dict['lower'] = [0.1,0.2,0.15]
data_dict['upper'] = [0.22,0.3,0.21]
dataset = pd.DataFrame(data_dict)

You can plot the confidence interval for each of these categories using the following code:

for lower,upper,y in zip(dataset['lower'],dataset['upper'],range(len(dataset))):
    plt.plot((lower,upper),(y,y),'ro-',color='orange')
plt.yticks(range(len(dataset)),list(dataset['category']))

Resulting with the following graph:
