[파이썬!] 파이썬으로 그래프 그리기

***

파이썬을 이용해 그래프를 그려보았다.
1. y=x<sup>2</sup>
2. y=sin(x)

두 그래프를 그려보자.

#### 입력
```
import numpy as np
%matplotlib inline
import matplotlib.pyplot as plt
x=np.linspace(-10,10,100)
y=x**2
plt.plot(x,y)
```

#### 결과
![20181106-141504.png](https://ipfs.busy.org/ipfs/QmfBXzqYnKU7NWSNcGaJmVjeFH6VCXhdvAy4Uq6DxRUuUM)

여기에서 조금 더 보완하면
x,y축 라벨과 그래프 제목 등을 넣을 수 있다.

###### x축 y축 라벨 넣기
```
plt.xlabel("x")
plt.ylabel("y")
```
###### 그래프 제목 넣기
```
plt.title("Y=X^2")
```

#### 사인함수
```
import numpy as np
%matplotlib inline
import matplotlib.pyplot as plt
x=np.linspace(-5,5,100)
y=np.sin(x)
plt.plot(x,y)
```
