如何解决密谋：如何在折线图上显示指定阈值的不同颜色段？ 情节完整代码

我有一个多线图，显示了随时间的增长百分比。我想在代码中设置一个阈值以具有上限和下限。如果线超出了这些界限，我希望线图的特定部分的颜色与其父级不同。

这就是我在做什么： 

import plotly.express as px
import plotly.graph_objects as go



fig = px.line(df14,x = "Date",y = "Percent",color = "POD",title = "POD Growth in Percentage (US)",labels = {"Percent": "Percent Growth"})

fig.update_layout(
font_family="Arial",font_color="black",title_font_family="Arial",title_font_color="black",legend_title_font_color="black"                                           #style the text (legend,title etc)
)


fig.update_xaxes(title_font_family="Arial")                               #style ance center title
fig.update_layout(
title={
    'text': "POD Growth Percentage in US (Line Graph)",'y':0.9,'x':0.5,'xanchor': 'center','yanchor': 'top'})


fig.update_traces(mode='markers+lines')                                    #add dots to line

fig.show()

这是视觉效果：

让我放大一行以更好地说明：

我希望为每个POD设置一个阈值，并且如果该行高于或低于此阈值，则该行的该部分的颜色将有所不同 。例如：

POD IAD的上限可能是5，IAD的下限可能是0。 任何大于5或小于0的值都将以特定颜色突出显示。

POD SJC的上限可能是10，SJC的下限可能是3 任何大于10或小于3的值都应突出显示为特定颜色。

我想要每个POD的阈值

请参见以下内容：

线条的突出显示的黄色部分反映了折线图超出或减小了设置阈值的位置。使用Plotly可以做到这一点吗？

任何建议都值得赞赏

更新

是否有一种方法可以使整行在其上显示标记点？ 我已经尝试过：mode ='markers + lines'但没有得到想要的结果：

**Update,I have figured this out:** 
fig.update_traces(mode='markers+lines')

enter image description here

更新的问题：

还可以在此处在悬停注释上添加日期和百分比标题吗？我正在研究Plotly文档。

enter image description here

解决方法

我整理了一条建议，该建议应完全符合您的要求。下图是由下面的代码示例产生的。该代码使用的词典包含针对您的不同POD的不同上限和下限，以及为不同容器设置不同颜色的可能性：

lim = {'IAD': {'lower': 90,'upper': 350,'color':'yellow'},'SJCtest': {'lower': 10,'upper': 12,'color':'green'}}

情节

enter image description here

我很想先过滤您的数据框，然后在此基础上向图中添加新的迹线。但是我的解决方案实际上是遍历每个迹线的每个数据点，并根据上面的字典为这些点着色。因此，无需任何数据处理。看看，进行一些测试，然后让我知道它如何为您工作。
