色度图未显示颜色

Question

我有一个数据集

data2 = dict(type = 'choropleth',
           locations = df3['Code'],
           z = df3['Power Consumption KWH'])
layout2 = dict(title = '2014 Global Power Consumption',
             geo = dict(showframe = False, projection = {'type': 'natural earth'}))

choromap2 = go.Figure(data = [data2], layout=layout2)
iplot(choromap2)

此后，我创建了一个弧度，但是我的问题是地图没有显示任何颜色，只显示了地球形状。

谢谢！

Answer 1

我尝试复制您的数据，发现您缺少一个重要参数，即locationmode = "country names"。添加它应该可以

data2 = dict(type = 'choropleth',
           locations = df['Code'],
            locationmode = "country names", # add this 
           z = df['Power Consumption KWH'])
layout2 = dict(title = '2014 Global Power Consumption',
             geo = dict(showframe = False, projection = {'type': 'natural earth'}))

choromap2 = go.Figure(data = [data2], layout=layout2)
iplot(choromap2)
