# plt.plot(data.a,data.car,c='green', label ='car')

# data3['left'].plot( c='red', label ='left lane')
# data3['right'].plot(c='blue', label ='right lane')
# plt.plot(data3.a,data3.car,c='green', label ='car')

data4['left'].plot( c='red', label ='left lane')
data4['right'].plot(c='blue', label ='right lane')
data4['car'].plot(c='green', label ='car')

plt.xlabel('data',size=25)
plt.xticks(fontsize=20)
plt.yticks(fontsize=20)
plt.ylabel('cm',size= 25)

plt.legend(fontsize=15)
plt.grid()
