python - 如何在x轴上的值范围上制作条形图并计算y轴上的范围？

Question

I have a list such as [0.2,0.4,1.2,2.4,5.4,6.0,0.3,3.4..] and I want to group the values in the list to a range(interval can change for different inputs) 0-1 , 1-2 , 2-3 and would like to plot a graph where the x-axis is the range and y-axis depicts the no_of_values in the given range?

For the above problem, {0-1:3,1-2:1,2-3:1,3-4:1,4-5:0,5-6:2}

Thanks in advance

Answer 1

Try using pandas.DataFrame.hist

pd.DataFrame(ls).hist()

where ls = [0.2,0.4,1.2,2.4,5.4,6.0,0.3,3.4]
