value error while plotting

[satya0210]

after calculating the value count by using group by i got a data frame
class
tt h A B C
1 1 50% 50% 0

24 24 25% 25% 50%

Now i want to plot them by using
fig,ax = plt.subplots(figsize=(20,8))

x=K['HOUR']
y1=K['A']
y2=K['B']
y3=K['C']
y4=K['D']
y5=K['E']
y6=K['F']
y7=K['G']

ax.plot(x,y1,color="red", marker="o", label='A',linewidth='4')

but it is showing error
ValueError: Multi-dimensional indexing (e.g. obj[:, None]) is no longer supported. Convert to a numpy array before indexing instead.
previously I used same code to plot then it shows now it is not showing

This looks unrelated to JAX; I'd suggest posting your question on StackOverflow with the pandas and matplotlib tags.
