Why am I receiving this error when using pylab to make a bar graph-CodePudding

I am using data from a file to make a bar graph using pylab. When I run it I get a very long error code.

This is my code.

bar_width=0.5
x_values=[1,2,3,4,5,6,7,8,9,10]
y_values=[3,2,5,7,4,10,12]
tlabel=["0-10", "11-20", "21-30", "31-40", "41-50", "51-60", "61-70", "71-80", "81-90", "Above 90"]
#pylab.xticks(range(6),rotation=30)
pylab.title("Homicide Occurance by Age")
pylab.bar(x_values,y_values,width=bar_width,tick_label=tlabel, align='center',color='b')
pylab.show()

And here is the error message I am receiving.

CodePudding user response：

you have 10 x_values but only 7 y_values. Try to run the same code with balanced data.
