plotly hoverlabel 颜色透明度 [英] plotly hoverlabel color transparency

问题描述

是否可以格式化 hoverlabel 使背景颜色透明&可以通过标签看到剧情吗?

Is it possible to format hoverlabel so that the background color is transparent & it's possible to see the plot through the labels?

我可以将其设置为纯色，例如hoverlabel = list(bgcolor = '#fff') 但看起来如果我尝试添加透明度，颜色字符串的那部分会被忽略.与 bgcolor = 'rgba(255,255,255,0.05)' 相同，也不起作用.看起来标记有 opacity 设置，但没有悬停标签.

I can set it to a solid color by e.g. hoverlabel = list(bgcolor = '#fff') but looks like if I try to add transparency, that part of the color string gets ignored. Same with bgcolor = 'rgba(255,255,255,0.05)', doesn't work either. Looks like for markers there is opacity setting, but not for hoverlabels.

谢谢！！

推荐答案

我发现(在 plotly python 中)，如果你在 layout，那么如果你将 bgcolor 设置为一些包含透明度的 rgba 值，它确实有效！我不知道 R 代码，但应该很容易弄清楚.这就是它的样子(我觉得很恶心！)-

I have found (in plotly python), that if you pass hovermode = "x unified" in layout, then if you set bgcolor to some rgba value that includes transparency, it does work! I am not aware of the R code for that but it should be easy to figure out. Here's what it looks like (pretty sick imo!) -

这是(python)代码-

Here's the (python) code-

fig.update_layout(hovermode='x unified', legend=dict(title= None), hoverlabel=dict(bgcolor='rgba(255,255,255,0.75)',
                                                                                  font=dict(color='black')))
