我是Python和Pandas的新手.我正在尝试将Pandas Dataframe转换为嵌套的JSON.函数.to_json()没有给我足够的灵活性来实现我的目标.
以下是数据帧的一些数据点(以csv,逗号分隔):
,ID,Location,Country,Latitude,Longitude,timestamp,tide
0,1,BREST,FRA,48.383,-4.495,1807-01-01,6905.0

有很多重复的信息,我想有这样的JSON:
[
{
"ID": 1,
"Location": "BREST",
"Latitude": 48.383,
"Longitude": -4.495,
"Country": "FRA",
"Tide-Data": {
"1807-02-01": 6931,
"1807-03-01": 6896,
"1807-04-01": 6953,
"1807-05-01": 7043
}
},
{
"ID": 5,
"Location": "HOLYHEAD",
"Latitude": 53.31399999999999,
"Longitude": -4.62,
"Country": "GBR", …我尝试从两个不同的来源加载数据.加载数据后我想在一个防暴标记文件中使用它.但我不明白如何加载第二个文件,因为我真的不了解异步调用.
我需要在代码中修改什么才能获取数据？现在,第二个数据对象未定义.这是我的代码:
import { csv, json } from 'd3-fetch'
csv('/data/stations.csv', function (stations) {
json('data/svg_data.json', function (svg) {
return svg
})
stations.position_x = +stations.position_x
stations.position_y = +stations.position_y
stations.animation_time = +stations.animation_time
stations.text_x = +stations.text_x
stations.text_y = +stations.text_y
return stations
}).then(function (stations, svg) {
mount('metro-app', {
stations: stations,
svg_data: svg
})
})
我有一个粘性div，如果我滚动过去，它会停留在顶部。但它会调整为全屏尺寸，我希望它保持相同的尺寸。
这是包装器和粘性类的CSS代码：
.wrapper{
margin: 0 auto;
width: 100%;
height: 180px;
background-color:#fff;
border-top: 0;
-webkit-box-shadow: 0 8px 6px -6px #B8B8B8;
-moz-box-shadow: 0 8px 6px -6px #B8B8B8;
box-shadow: 0 8px 6px -6px #B8B8B8;
}
.sticky {
width: 100%;
position: fixed;
left: 0;
top: 0;
z-index: 100;
border-top: 0;
padding-left: 15px;
padding-right: 15px;
-webkit-box-shadow: 0 8px 6px -6px #B8B8B8;
-moz-box-shadow: 0 8px 6px -6px #B8B8B8;
box-shadow: 0 8px 6px -6px #B8B8B8;
}
这是JS代码：
var global = {};
$(document).ready(function(){
var element = $(".wrapper");
offset …我正在尝试更改地图集群集地图中的文本颜色(https://www.mapbox.com/mapbox-gl-js/example/cluster/),但我无法弄清楚如何.
以下是相关代码:
map.addLayer({
id: "cluster-count",
type: "symbol",
source: "grundbuch",
filter: ["has", "point_count"],
layout: {
"text-field": "{point_count_abbreviated}",
"text-font": ["DIN Offc Pro Medium", "Arial Unicode MS Bold"],
"text-size": 12
}
});
有人知道怎么做这个吗？我想将数字标签更改为白色.
