无法在 r Z531704A02607A1646EFCF4C1FAEEE1 应用程序中更改条形图 plotly 上标记的 colors

[英]unable to change colors of markers on barplot plotly in a r shiny application

我目前正在开发一个 shiny 应用程序,并且我开始使用 Plotly 来制作一些图表。 问题是我希望我的条形图是这样的:气压图

然而,这是我写的代码的结果图条形图2

plot的代码:

 plot_ly(data =gfrq1, x= ~a, y= ~b, source = 'brand',type = 'bar',name = ~is.true, color = ~is.true, colors = c('TRUE' = "#B22222", 'FALSE' = '#808080'))%>% 
 add_trace(data = gfrq2, x = ~a, y= ~b, type = 'scatter', mode = 'marker+point',  name = ~data, marker = list( size =10 , color = ~data,colors = ~data)) 

数据集是这些:

dput(gfrq1)
structure(list(a = c("person1", "person2", "person3", "person4", 
"person5", "person6", "person7", "person8", "person9", "person10", 
"person11", "person12", "person13", "person14", "person15"), 
    b = c(0.452, 0.46, 0.456, 0.444, 0.458, 0.459, 0.446, 0.461, 
    0.458, 0.459, 0.461, 0.467, 0.467, 0.451, 0.571), is.true = c(FALSE, 
    FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, 
    FALSE, FALSE, FALSE, FALSE, FALSE)), row.names = c(NA, -15L
), class = "data.frame")

dput(gfrq2)
structure(list(a = c("person1", "person2", "person3", "person4", 
"person5", "person6", "person7", "person8", "person9", "person10", 
"person11", "person12", "person13", "person14", "person15"), 
    b = c(0.049109883364027, 0.0478821362799263, 0.0466543891958257, 
    0.26051282051282, 0.0460405156537753, 0.0466543891958257, 
    0.262222222222222, 0.0445058317986495, 0.041743400859423, 
    0.0426642111724985, 0.0441988950276243, 0.049109883364027, 
    0.0500306936771025, 0.266666666666667, 0.571428571428571), 
    data = c("data1", "data1", "data1", "data1", "data3", "data3", 
    "data1", "data2", "data3", "data3", "data1", "data1", "data3", 
    "data1", "data4"), is.true = c(FALSE, FALSE, FALSE, FALSE, 
    FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, FALSE, FALSE, FALSE, 
    FALSE, FALSE)), row.names = c(NA, -15L), class = "data.frame")

有什么建议么?

我很惊讶 Plotly 在这方面的不合作 不幸的是,我不得不承认我偶然发现了解决方案。

我将数据加入到一个数据框中。 不要使用标记的参数color ,而是split

我从add_bars中删除了参数name ,因为使用该设置,图例反映了“is.true”和“TRUE”。 (为什么 Plotly 不能读懂我的想法?)

ggdat <- cbind(gfrq1, gfrq2[, c("b","data")])       # join data
names(ggdat) <- c("a", "b", "is.true", "b2", "dat") # fix names

plot_ly(data = ggdat, x = ~a) %>% 
  add_bars(y = ~b, color = ~is.true, 
           colors = c('TRUE' = "#B22222", 'FALSE' = '#808080')) %>% 
  add_markers(y = ~b2, split = ~dat, marker = list(size = 10))

我很确定没有markers+point模式。 对于点、点、散点...等,模式是markers (不过,我可能是错的!)

在此处输入图像描述
