我一直在尝试使用 plotly R 库创建网络图.我想可视化一个自定义 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.
I have been trying to create a network graph with the plotly R library. I would like to visualize a custom hoverinfo text that is different from the text label defined for the markers (or nodes in this case).
基本上，我希望将标记(节点)上的文本标签保持原样，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与标记的标签文本不同的其他字符向量.例如，当我将鼠标悬停在中央Shigeru Miyamoto"节点上时，我想显示工具提示以显示我可能收集的其他信息(例如类型、国籍等).我对 plotly 文档的理解是，目前您只能为标记和 hoverinfo 工具提示显示相同的文本标签.
Basically, I would like to keep the text labels on the markers (nodes) as they are currently but also be able to provide custom text for the hoverinfo. As in I would like the tooltip to display some other character vector different from the marker's label text. For instance, when I hover on the central 'Shigeru Miyamoto' node, I would like to tooltip to display other information that I may collect (eg. type, nationality etc). My understanding from the plotly documentation is that currently you can only display the same text label for both the markers and the hoverinfo tooltip.
有没有办法做到这一点?
Is there a way to accomplish this?
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,]$V2 edge_shape = list( type = "line", line = list(color = "DF691A", width = 1), x0 = Xn[match(v0,names(vs))], y0 = Yn[match(v0,names(vs))], x1 = Xn[match(v1,names(vs))], y1 = Yn[match(v1,names(vs))], opacity = 0.3 ) edge_shapes[[i]] <- edge_shape} network <- layout( network, paper_bgcolor="#4e5d6c", plot_bgcolor="#4e5d6c", hovermode = "closest", title = paste("Miyamoto's Relations",sep = ""), titlefont=list(color="white"), shapes = edge_shapes, xaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE), yaxis = list(title = "", showgrid = FALSE, showticklabels = FALSE, zeroline = FALSE) ) network 推荐答案经过进一步研究，我认为我找到了一个潜在的解决方案，即使用 annotations.想法是隐藏 markers 而是使用 annotations 作为节点标签.这样，您可以为 hoverinfo 工具提示文本包含任意字符向量.
Upon further research, I think I found a potential solution by using annotations.The idea is to hide the text from the markersand instead use annotations for the node labels. This way you can include any arbitrary character vector for the hoverinfo tooltip texts.
hover_text <- rep('Game Designer/Mario Creator',11) size = c(100,rep(40,length(vs)-1)) network <- plot_ly(type = "scatter", x = Xn, y = Yn, mode = "markers", text = hover_text, hoverinfo = "text",marker=list(size=size,color='5BC0DE') ) edge_shapes <- list() for(i in 1:Ne) { v0 <- es[i,]$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)) ) network更多推荐
