This article mainly introduces "how to draw horizontal bar bar chart by python". In daily operation, I believe that many people have doubts about how to draw horizontal bar bar chart by python. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the question of "how to draw horizontal bar bar chart by python". Next, please follow the editor to study!

The specific code is as follows

Import matplotlibimport randomimport matplotlib.pyplot as plt # Chinese garbled code and axis negative sign processing. Matplotlib.rc ('font', family='SimHei', weight='bold') plt.rcParams [' axes.unicode_minus'] = False # city data City_name = ['Beijing', 'Shanghai', 'Guangzhou', 'Shenzhen', 'Chengdu'] # array inversion. City_name.reverse () # loads random data. Data = [] for i in range (len (city_name)): data.append (random.randint (100,150)) # drawing Fig, ax = plt.subplots () b = ax.barh (range (len (city_name)), data, color='#6699CC') # add data labels to the right side of the horizontal bar chart. For rect in b: W = rect.get_width () ax.text (w, rect.get_y () + rect.get_height () / 2,'% d'% int (w), ha='left', va='center') # sets the tick mark label on the Y axis ordinate. Ax.set_yticks (range (len (city_name)) ax.set_yticklabels (city_name) # do not want the label tag on the X Abscissa. Plt.xticks (()) plt.title ('horizontal bar chart', loc='center', fontsize='25', fontweight='bold', color='red') plt.show ()

Running result:

You can simply draw a horizontal bar chart:

Import matplotlib.pyplot as pltimport randomimport matplotlib matplotlib.rc ('font', family='SimHei', weight='bold') city_name = [' Beijing', 'Shanghai', 'Guangzhou', 'Shenzhen', 'Chengdu'] city_name.reverse () data = [] for i in range (len (city_name)): data.append (random.randint (100,200)) colors = ['red',' yellow', 'blue',' green' 'gray'] colors.reverse () plt.barh (range (len (data)), data, tick_label=city_name, color=colors) # No X Abscissa labels. # plt.xticks () plt.show ()

The output is shown in the figure:
