如何在 plotly pie 中调整悬停标签内的长文本字符串？

Question

我想在我的饼图上的悬停标签内放置一个长文本字符串。我希望文本自动适应标签，以便正确显示。

此外，我想删除 Trace 0

示例数据集：

df.prescripciones.3.direccionadas.grafica = structure(list(IPS = c("UNIDAD ESPECIALIZADA EN ALERGIA Y ENFERMEDAD RESPIRATORIA SAS", 
"HOSPITAL INTERNACIONAL DE COLOMBIA", "FUNDACION CARDIOVASCULAR DE COLOMBIA - INSTITUTO CARDIOVASCULAR", 
"Hospital Virtual", "INSTITUTO DE MEDICINA AMBULATORIA Y PREVENTIVA IMAP", 
"MEDYSER IPS", "FUNDACION OFTALMOLOGICA DE SDER FOSCAL", "ESE HOSPITAL PSIQUIÁTRICO SAN CAMILO", 
"Total"), `2021-06` = c(113844, 113844, 65234911, 113844, 
113844, 113844, 113844, 113844, 113844), Total = c(113844, 
113844, 65234911, 113844, 113844, 113844, 113844, 113844, 
113844)), row.names = c(NA, -9L), class = c("tabyl", "tbl_df", 
"tbl", "data.frame"), core = structure(list(IPS = c("UNIDAD ESPECIALIZADA EN ALERGIA Y ENFERMEDAD RESPIRATORIA SAS", 
"HOSPITAL INTERNACIONAL DE COLOMBIA", "FUNDACION CARDIOVASCULAR DE COLOMBIA - INSTITUTO CARDIOVASCULAR", 
"Hospital Virtual", "INSTITUTO DE MEDICINA AMBULATORIA Y PREVENTIVA IMAP", 
"MEDYSER IPS", "FUNDACION OFTALMOLOGICA DE SDER FOSCAL", "ESE HOSPITAL PSIQUIÁTRICO SAN CAMILO"
), `2021-06` = c(113844, 189728293, 65234911, 37038984, 5506387, 
1198435, 1372392, 383629)), row.names = c(NA, -8L), class = "data.frame"), tabyl_type = "two_way", totals = c("col", 
"row"))

创建饼图的部分服务器代码：

paired1 <- brewer.pal(n = 10, name = "Paired")

  output$plot4 <- renderPlotly(
  plot4 <- plot_ly( df.prescripciones.3.direccionadas.grafica ,
                    labels = ~Profesional, 
                    values = ~Total,
                    type = 'pie',
                    marker = list(colors = paired1),
                    texttemplate = ~ paste ("<br>",
                                            "%{percent} <br>"),
                    hovertemplate = ~ paste (  Profesional,
                                               " <br>",IPS," <br>",
                                               "%{percent} <br>",
                                               "$","%{value} <br>" )  ) %>%
    layout( title = list  ( text = "Top 10 Profesionales"),
            font = list (size = 11) ,
            hoverlabel = list(font=list(size=11) ) ) %>% 
    layout(showlegend = F) %>%
    layout(legend = list(x = -0.5, y = 0.5)) %>% 
    layout(autosize = T,  margin = list(l = 25,
                                        r = 65,
                                        b = 40,
                                        t = 60))  %>%
    layout(plot_bgcolor  = "rgba(0, 0, 0, 0)",
           paper_bgcolor = "rgba(0, 0, 0, 0)"
    ) 
)

似乎没有关于定义文本长度的论据。但是您可以在 hovertemplate 中拆分长文本，因此每 x 个字符中断一次。

可以在 post 中找到纯文本的示例 - 使用了 gsub。在下面的代码中，将每 45 个字符添加一次中断。

要删除“Trace 0”，请在悬停模板末尾添加 <extra></extra>。

代码

 plot_ly( df.prescripciones.3.direccionadas.grafica ,
                    labels = ~IPS, 
                    values = ~Total,
                    type = 'pie',
                    marker = list(colors = paired1),
                    texttemplate = ~ paste ("<br>",
                                            "%{percent} <br>"),
# added gsub and <extra></extra>
                    hovertemplate = ~ paste (gsub('(.{1,45})(\s|$)', '\1\n', IPS),
                                               "%{percent} <br>",
                                               "$","%{value} <br> <extra></extra>" )) %>%
    layout( title = list  ( text = "Top 10 Profesionales"),
            font = list (size = 11) ,
            hoverlabel = list(font=list(size=11) ) ) %>% 
    layout(showlegend = F) %>%
    layout(legend = list(x = -0.5, y = 0.5)) %>% 
    layout(autosize = T,  margin = list(l = 25,
                                        r = 65,
                                        b = 40,
                                        t = 60))  %>%
    layout(plot_bgcolor  = "rgba(0, 0, 0, 0)",
           paper_bgcolor = "rgba(0, 0, 0, 0)"
    )
