在情节R图表上的自定义hoverinfo文本与'文本'不同。参数?

我一直在尝试使用plotly R库创建网络图。我想要显示一个自定义hoverinfo文本与为标记(或本例中的节点)定义的文本标签不同。

基本上,我希望将文本标签保留在当前的标记(节点)上,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的标签文本的其他字符向量。例如,当我将鼠标悬停在中央的宫本茂(Shigeru Miyamoto)身上时。节点,我想工具提示显示我可能收集的其他信息(例如,类型,国籍等)。我从图解文档中了解到,目前您只能为标记和hoverinfo工具提示显示相同的文本标签。

有没有办法实现这个目标?

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,我认为我使用annotations找到了一个潜在的解决方案。我们的想法是隐藏markers中的文字,而是使用annotations作为节点标签。这样,您可以为hoverinfo工具提示文本添加任意字符向量。

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))
        )
