出租车数据的地图展示

实现方法

python数据预处理后将数据导入地图代码。

效果

数据预处理：

f1['dropoff_longitude'].fillna(value=f1['dropoff_longitude'].mean(), inplace=True)
plt.boxplot(f1["dropoff_longitude"])
plt.show()
#超过了上四分位1.5倍四分位距或下四分位1.5倍距离都算异常值，用中位数填充
a = f1["dropoff_longitude"].quantile(0.75)
b = f1["dropoff_longitude"].quantile(0.25)
c = f1["dropoff_longitude"]
c[(c>=(a-b)*1.5+a)|(c<=b-(a-b)*1.5)]=np.nan
c.fillna(c.median(),inplace=True)
