Plotly Express 散点图不绘制整个范围的 x 变量

Question

我正在尝试使用 Plotly Express 创建一个散点图，绘制 75 个国家/地区样本中随时间变化的平均温度。但是图表上只显示了34个国家，图例中并没有显示所有的县。

可以显示的变量数量是否有限制，或者是否缺少某些参数。我的代码在下面供参考；

fig=px.scatter(df, x= 'Country', y='Temperature', animation_frame='YR',
           animation_group='Country',size='Temperature', color='Country', 
           hover_name='Country',width=1000, height=600, 
           range_y=[2,35])

Answer 1

x-axis 个刻度线变细了，所以它们没有全部显示出来。如果您在 tickvals 的列表中给出所有国家/地区，它们将全部显示。

fig=px.scatter(df, x='Country',
               y='Temperature',
               animation_frame='YR',
               animation_group='Country',
               size='Temperature',
               color='Country',
               hover_name='Country',
               width=1000,
               height=600,
               #range_y=[2,35]
              )

fig['layout']['sliders'][0]['pad']['t'] = 150
fig['layout']['updatemenus'][0]['pad']['t'] = 150
fig.update_layout(
    autosize=False,
    width=1000,
    showlegend=True
)
fig.update_xaxes(type='category', tickvals=df['Country'].tolist())
fig.show()
