使用 MatPlotLib 绘制数据

Question

I'm starting my first data science project. First step is to plot all shots from the 2018 NHL season. Can't seem to figure out how to make the x and y coordinates pull from xCord and yCord columns both int64 data types.

import pandas as pd
import numpy as py
import matplotlib.pyplot as plt

shots = pd.read_csv('NHL_Project/Data/shots_2007-2020.csv')

shot = shots[['homeTeamCode', 'awayTeamCode', 'season','isPlayoffGame','game_id','homeTeamWon', 'period', 'time','period','team','location','event','goal','xCord','yCord','shotType','playerPositionThatDidEvent','playerNumThatDidEvent','goalieIdForShot','goalieNameForShot','shooterPlayerId','shooterName','shooterLeftRight','shotWasOnGoal']].head()

fig = plt.figure(figsize=(100,100))
ax = plt.axes()
t = py.linspace(-100, 100, 100) # return 100 numbers between -100 and 100
x = ['xCord']
y = ['yCord']

ax.plot(x, y, color='red', marker='D')

Answer 1

Didn't run this code, cause I don't have your data, but it should work.

You should get the x and y from your dataframe, but both of them are set as a list, [xCord'] and [yCord] .

import pandas as pd
import numpy as py
import matplotlib.pyplot as plt

shots = pd.read_csv('NHL_Project/Data/shots_2007-2020.csv')

shot = shots[['homeTeamCode', 'awayTeamCode', 'season','isPlayoffGame','game_id','homeTeamWon', 'period', 'time','period','team','location','event','goal','xCord','yCord','shotType','playerPositionThatDidEvent','playerNumThatDidEvent','goalieIdForShot','goalieNameForShot','shooterPlayerId','shooterName','shooterLeftRight','shotWasOnGoal']].head()

fig = plt.figure(figsize=(100,100))
ax = plt.axes()
t = py.linspace(-100, 100, 100) # return 100 numbers between -100 and 100

ax.plot(x=shots.xCord, y=shots.yCord, color='red', marker='D')
