Import Module

1 Import Matplotlib.pyplot as Plt 2 import Seaborn as SB

Draw a bar chart

Countplot (data: Datasets, x:x axes, color: bar colors, order: Sort)

Color_palette (): Returns an RGB tuple list

Test = Pd.read_csv ('Pokemon.csv')Print(Test.shape)Print(Test.tail (10))#The value_counts function counts the frequency of each sequence and descendingGeneration_order = test['generation_id'].value_counts (). IndexPrint(Generation_order)#Color_palette returns an RGB tuple listBase_color =Sb.color_palette () [0]sb.countplot (Data=test, x='generation_id', Color=base_color, order=generation_order) plt.show ()

xticks (Rotation: Rotation degree): Change the direction of the plotted x-axis labels (number of counter-clockwise grips with horizontal direction)

yticks (Rotation: Rotation degrees): Change the direction of the plotted y-axis labels (the number of counterclockwise clamp angles in the vertical direction)
