x-axis inverted unexpectedly by pandas.plot(…)

Question

X axis was inverted automatically and unexpectedly when plotting a series of data against another series of data using pandas. Please look at my code below. How can I ensure

Answer 1

To invert the graph you can use

arr1 = [1,2,3,4,5]
arr2 = [9,8,4,3,8]
df = pd.Dataframe(arr1,arr2)
df.plot.barh()

if you also want to print the graph in sorting then you can use

df.sort_values().plot.barh()

To enlarge the size of graph you can use

df.sort_values().plot.barh(figsize=(10,20))
