用python中的gmplot绘制散点图时的错误

Question

我想在python中使用 gmplot lib绘制散点图。但是，我想为每个图(对于每个坐标(使Marker_Size不同。我写了一个代码，我得到了这个错误：

TypeError: unsupported operand type(s) for /: 'tuple' and 'float'

marker_size值是整数。

这是代码：

from gmplot import gmplot
import pandas as pd
df = pd.read_csv('tripdataNEW.csv')
def geolocation_scatter(input_data, file_name):
    #extract only coordinates and marker_size and convert them to tuple
    coordinates_data = input_data[["start station latitude", "start station longitude", "marker_size"]]
    coordinates_data = coordinates_data.apply(tuple, axis=1)
    #add tuple coordinates to list
    coordinate_list = []
    for coord in coordinates_data:
        coordinate_list.append(coord)
    # Scatter points
    coordinate_lats, coordinate_lons, marker_size = zip(*coordinate_list)
    # Defult map location
    gmap = gmplot.GoogleMapPlotter(40.7423543, -73.98915076, 13)
    #Scatter dots on the map
    gmap.scatter(coordinate_lats, coordinate_lons, 'red', size = marker_size, marker = False)
    # Draw
    name = str(file_name)+".html"
    gmap.draw(name)
print(geolocation_scatter(df ,"SCATTER"))

Answer 1

我认为您的问题与行：

gmap.scatter(coordinate_lats, coordinate_lons, 'red', size = marker_size, marker = False)

虽然您可以通过" coortion_lats"one_answers" coortion_lons"传递一个疑问，但我相信arg" size"正在期望浮点参数，而不是元组(因此错误(。我不确定它旨在允许每个点都具有不同的颜色，它可能期望整个系列的大小相同。您可能只需循环浏览此通话即可获得所需的效果。喜欢：

# Scatter points
coordinate_lats, coordinate_lons, marker_size = zip(*coordinate_list)
# Defult map location
gmap = gmplot.GoogleMapPlotter(40.7423543, -73.98915076, 13)
#Scatter dots on the map
for coord_lat, coord_lon, m_size in zip(coordinate_lats, coordinate_lons, marker_size):
    gmap.scatter(coord_lat, coord_lon, 'red', size = m_size , marker = False)
