问题描述

我想用GeoChart显示法国地区的地图。

https://developers.google.com/chart/interactive/docs/gallery/geochart#regions-mode-format



在前面的链接中提到的ISO 3166代码是,例如,普罗旺斯 - 阿尔卑斯 - 科特迪瓦省的 FR-U d'Azur地区。



https://en.wikipedia.org/wiki/Provence-Alpes-C%C3%B4te_d 'Azur



以下是我的选项:

  var options = {
region:'FR-U',
displayMode:'markers',
colorAxis:{颜色:['green','blue']}
};

然而这不起作用。我收到以下错误消息:请求的映射不存在。。这不是由于我的代码,因为如果我把 FR 而不是 FR-U ,它可以正常工作。



地图是否存在?

解决方案

您引用的链接是 数据格式 区域图



,并与



region 接受以下内容...


'world' - Geochart of整个世界。

一个大陆或亚洲大陆,由其3位代码指定,例如西非的'011'。

一个国家,由其ISO 3166-1 alpha-2代码指定,例如澳大利亚的AU。

美国的一个州,由其ISO 3166-2:美国代码指定,例如,用于阿拉巴马州的US-AL。请注意,解决方案选项必须设置为省或metros。


请参阅法国以下示例...



请注意分辨率



  google.charts.load('current',{callback:function(){new google.visualization.GeoChart(document.getElementById('chart_div'))。draw(google.visualization.arrayToDataTable [['Destination','Popularity'],['FR-A',100],['FR-B',105],['FR-C',110],['FR-P',115] ,''FR-D',120],['FR-E',125],['FR-F',130],['FR-G',140],['FR- ,['FR-I',160],['FR-Q',175],['FR-J',190],['FR-K',215] , ['FR-M',255],['FR-N',280],['FR-O',305],['FR-R',335],['FR-S',365] ['FR-T',400],['FR-U',440],['FR-V',480],]),{colorAxis:{colors:['green','blue']} displayMode:'regions',region:'FR',resolution:'provinces'}); },packages:['geochart']});

I want to display a map of a region of France with GeoChart.

https://developers.google.com/chart/interactive/docs/gallery/geochart#regions-mode-format

The ISO 3166 code mentionned in the previous link is, for example, FR-U for the Provence-Alpes-Côte d'Azur region.

https://en.wikipedia.org/wiki/Provence-Alpes-C%C3%B4te_d'Azur

Here's my options:

var options = {
    region: 'FR-U',
    displayMode: 'markers',
    colorAxis: {colors: ['green', 'blue']}
};

However this does not works. I'm getting the following error message: Requested map does not exist.. This is not due to my code since if I put FR instead of FR-U it works fine.

Is the map simply not existing?

解决方案

the link you reference is the Data Format for a Regions chart

and is separate from the Configuration Options

the option for region accepts the following...

'world' - A geochart of the entire world.

A continent or a sub-continent, specified by its 3-digit code, e.g., '011' for Western Africa.

A country, specified by its ISO 3166-1 alpha-2 code, e.g., 'AU' for Australia.

A state in the United States, specified by its ISO 3166-2:US code, e.g., 'US-AL' for Alabama. Note that the resolution option must be set to either 'provinces' or 'metros'.

see following example for France...

note the resolution

google.charts.load('current', {
  callback: function () {
    new google.visualization.GeoChart(document.getElementById('chart_div')).draw(
      google.visualization.arrayToDataTable([
        ['Destination', 'Popularity'],
        ['FR-A', 100],
        ['FR-B', 105],
        ['FR-C', 110],
        ['FR-P', 115],
        ['FR-D', 120],
        ['FR-E', 125],
        ['FR-F', 130],
        ['FR-G', 140],
        ['FR-H', 150],
        ['FR-I', 160],
        ['FR-Q', 175],
        ['FR-J', 190],
        ['FR-K', 215],
        ['FR-L', 235],
        ['FR-M', 255],
        ['FR-N', 280],
        ['FR-O', 305],
        ['FR-R', 335],
        ['FR-S', 365],
        ['FR-T', 400],
        ['FR-U', 440],
        ['FR-V', 480],
      ]),
      {
        colorAxis: {colors: ['green', 'blue']},
        displayMode: 'regions',
        region: 'FR',
        resolution: 'provinces'
      }
    );
  },
  packages:['geochart']
});
