与 'text' 参数不同的 plotly R 图表上的自定义 hoverinfo 文本？

Question

我一直在尝试使用 plotly R 库创建网络图。我想可视化自定义 hoverinfo 文本，该文本 不同于为标记（或本例中的节点）定义的文本标签 。

基本上，我想保留标记（节点）上的文本标签，因为它们是当前的，但也能够为 hoverinfo 提供自定义文本。正如我希望工具提示显示一些不同于标记标签文本的其他字符向量。例如，当我将鼠标悬停在中央 'Shigeru Miyamoto' 节点上时，我想通过工具提示显示我可能收集的其他信息（例如类型、国籍等）。我从 plotly 文档中了解到，目前您只能为标记和 hoverinfo 工具提示显示相同的文本标签。

有没有办法做到这一点？

这是我使用的代码：

library(plotly)
library(igraph)
library(dplyr)

A <- data.frame(A=rep("Shigeru Miyamoto",10))

B <- data.frame(B=c("Ninendo Company Ltd","Super Mario Bros","Mario", "Gamespot","Time Magazine","Wii","DOnkey Kong Jr","Mario Kart","Japan","Mario Party"))

edgelist <- bind_cols(A,B)

graph <- graph_from_data_frame(edgelist)
L <- layout_nicely(graph)
vs <- V(graph)
es <- as.data.frame(get.edgelist(graph))
Ne <- length(es[1]$V1)
Xn <- L[,1]
Yn <- L[,2]

txt <- list(
        family = "calibri",
        size = 15,
        color = "white",
        opacity = 1
)

size = c(20,rep(5,length(vs)-1))


network <- plot_ly(type = "scatter", x = Xn, y = Yn, mode = "markers+text", 
                   text = names(vs), hoverinfo = "text",marker=list(size=size,color='5BC0DE'), textfont = txt

)


edge_shapes <- list()
for(i in 1:Ne) {
        v0 <- es[i,]$V1
        v1 <- es[i,]$V2

        edge_shape = list(
                type = "line",
                line = list(color = "DF691A", width = 1),
                x0 = Xn[match(v0,names(vs))],
                y0 = Yn[match(v0,names(vs))],
                x1 = Xn[match(v1,names(vs))],
                y1 = Yn[match(v1,names(vs))],
                opacity = 0.3
        )

        edge_shapes[[i]] <- edge_shape}

network <- layout(
        network,
        paper_bgcolor="#4e5d6c",
        plot_bgcolor="#4e5d6c",
        hovermode = "closest",
        title = paste("Miyamoto's Relations",sep = ""),
        titlefont=list(color="white"),
        shapes = edge_shapes,
        xaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE),
        yaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE)


)

经过进一步研究，我想我找到了一个使用 annotations 的潜在解决方案。我的想法是隐藏 markers 中的文本，而不是使用 annotations 作为节点标签.这样您就可以为 hoverinfo 工具提示文本包含任意字符向量。

hover_text <- rep('Game Designer/Mario Creator',11)

size = c(100,rep(40,length(vs)-1))


network <- plot_ly(type = "scatter", x = Xn, y = Yn, mode = "markers", 
                   text = hover_text, hoverinfo = "text",marker=list(size=size,color='5BC0DE')

)

edge_shapes <- list()
for(i in 1:Ne) {
        v0 <- es[i,]$V1
        v1 <- es[i,]$V2

        edge_shape = list(
                type = "line",
                line = list(color = "DF691A", width = 1),
                x0 = Xn[match(v0,names(vs))],
                y0 = Yn[match(v0,names(vs))],
                x1 = Xn[match(v1,names(vs))],
                y1 = Yn[match(v1,names(vs))],
                opacity = 0.3
        )

        edge_shapes[[i]] <- edge_shape}

network <- layout(
        network,
        paper_bgcolor="#4e5d6c",
        plot_bgcolor="#4e5d6c",
        hovermode = "closest",
        title = paste("Miyamoto's Relations",sep = ""),
        titlefont=list(color="white"),
        shapes = edge_shapes,
        xaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE),
        yaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE),
        annotations=list(x = Xn,
                y = Yn,
                text = names(vs),
                xref = "x",
                yref = "y",
                showarrow = F,
                font=list(family = "calibri",
                          size = 15,
                          color = "white",
                          opacity = 1))
        )
