如何使用场景将注释添加到scatter3D Plotly图？

debugcn 发表于 Dev

我正在尝试向具有不同场景的scatter3d Plotly图中的点添加文本注释。如何使注释随图一起移动？即使当我将xref和yref签名为“场景”时，注释也不会移动。

这是我尝试运行的可复制示例：

library(plotly)

rep.ex = data.frame(x1=1:20, y1=1:20, z1=(1:20)*2, text1=letters[1:20])

axoff <- list(title = "", zeroline = FALSE, showline = FALSE, showticklabels = FALSE, showgrid = FALSE, autotick = F)
axoffxy <- list(title = "", zeroline = FALSE, showline = FALSE, showticklabels = FALSE, showgrid = FALSE, autotick = F, showspikes=F)


plot_ly(data=data.frame(rep.ex), x=rep.ex$x1, y=rep.ex$y1, z=rep.ex$z1, 
            marker=list(size=2.6), 
            color=rep.ex$x1, hoverinfo='text',
            text=rep.ex$text1,
            type="scatter3d", mode = "markers") %>%
  layout(showlegend = T, dragmode="turntable", scene = list(aspectmode='cube', xaxis = axoffxy, yaxis = axoffxy, zaxis = axoff), 
         annotations=list(showarrow=FALSE, 
                          text='Here I insert my annotation',  
                          xref='scene',     
                          yref='scene',
                          zref='scene',
                          x=1,  
                          y=1, 
                          z=2,
                          xanchor='left',   
                          yanchor='bottom',  
                          font=list(size=12 )))

我正在使用Plotly版本4.9.0

如果您的问题允许您从布局中的注释切换到add_trace它，则它会四处移动。这样的事情将为此工作：

plot_ly(data=data.frame(rep.ex), x=rep.ex$x1, y=rep.ex$y1, z=rep.ex$z1, 
        marker=list(size=2.6), color=rep.ex$x1, hoverinfo='text',
        text=rep.ex$text1, type="scatter3d", mode = "markers", showlegend=F) %>%
  add_trace(type='scatter3d', mode='text', x=10,y=10,z=10, 
            text='Here I insert my annotation', showlegend=F, inherit=F) %>%
  layout(showlegend = T, dragmode="turntable", 
         scene = list(aspectmode='cube', xaxis = axoffxy, yaxis = axoffxy, zaxis = axoff))
