I am building a small tool for data analysis and I have come to the point, where I have to plot the prepared data. The code before this produces the following two lists with equal length.

t11 = ['00', '01', '02', '03', '04', '05', '10', '11', '12', '13', '14', '15', '20', '21', '22', '23', '24', '25', '30', '31', '32', '33', '34', '35', '40', '41', '42', '43', '44', '45', '50', '51', '52', '53', '54', '55']

t12 = [173, 135, 141, 148, 140, 149, 152, 178, 135, 96, 109, 164, 137, 152, 172, 149, 93, 78, 116, 81, 149, 202, 172, 99, 134, 85, 104, 172, 177, 150, 130, 131, 111, 99, 143, 194]

Based on this, I want to built a histogram with matplotlib.plt.hist. However, there are a couple of problems:
1. t11[x] and t12[x] are connected for all x. Where t11[x] is actually a string. It represents a certain detector combination. For example: ’01’ tells that the detection was made in the 0th segment of the first detector, and 1st segment of the second detector. My goal is to have each entry from t11 as a labeled point on the x axis. The t12 entry is going to define the hight of the bar above the t11 entry (on a logarithmic y axis)

How does one configure such an x axis?
2. This is all very new to me. I could not find anything related in the documentation. Most probably because I did not know what to search for. SO: Is there an “official” name for what I am trying to achieve. This would also help me alot.

    Use the xticks command.

    import matplotlib.pyplot as plt

t11 = ['00', '01', '02', '03', '04', '05', '10', '11', '12', '13', '14', '15',
       '20', '21', '22', '23', '24', '25', '30', '31', '32', '33', '34', '35',
       '40', '41', '42', '43', '44', '45', '50', '51', '52', '53', '54', '55']

t12 = [173, 135, 141, 148, 140, 149, 152, 178, 135, 96, 109, 164, 137, 152,
       172, 149, 93, 78, 116, 81, 149, 202, 172, 99, 134, 85, 104, 172, 177,
       150, 130, 131, 111, 99, 143, 194]


plt.bar(range(len(t12)), t12, align='center')
plt.xticks(range(len(t11)), t11, size='small')
plt.show()
