hoverformat仅适用于$符号，不适用于其他货币？

Question

我正在使用plot_ly库中的plotly作图。

我正在尝试使用S/货币，这是秘鲁货币“ nuevos soles”的符号。

在布局中使用hoverformat设置货币符号仅适用于美元：

plot_ly(ha, x = ~periodo, y = ~precio.actual, color = ~ecommerce, 
        colors = c("#BED800", "#802D69", "#FF5500")) %>%
    add_boxplot() %>%
    layout(yaxis = list(
        hoverformat = '$,.2f'
    )) %>% 
    config(displayModeBar = FALSE) 

但是如果我使用S/符号（请注意斜杠后的空白），则工具提示不会仅显示整数显示任何货币。

plot_ly(ha, x = ~periodo, y = ~precio.actual, color = ~ecommerce, 
            colors = c("#BED800", "#802D69", "#FF5500")) %>%
        add_boxplot() %>%
        layout(yaxis = list(
            hoverformat = 'S/ ,.2f'
        )) %>% 
        config(displayModeBar = FALSE)

数据：

ha <- structure(list(periodo = structure(c(2L, 2L, 2L, 2L, 2L, 2L), .Label = c("2017", 
"2016"), class = c("ordered", "factor")), ecommerce = structure(c(2L, 
2L, 2L, 2L, 2L, 2L), .Label = c("falabella", "ripley", "linio"
), class = c("ordered", "factor")), marca = c("samsung", "samsung", 
"lg", "lg", "samsung", "lg"), producto = c("samsung tv led hd 32'' 32j4000", 
"samsung smart tv led fhd 48\"\" 3d 48j6400", "lg smart tv led 43'' full hd 43lh5700", 
"lg smart tv led 49'' full hd 49lh5700", "samsung smart tv 50ju6500 led uhd 50\"\" - negro", 
"lg smart tv led 49\"\" ultra hd tv 49uh6500"), precio.antes = c(999, 
2799, 1649, 1999, 3699, 2799), precio.actual = c(799, 1999, 1249, 
1699, 2399, 2199), pulgadas = c(32, 48, 43, 49, 50, 49), rango = c("S/.500 -\r\n S/.1500", 
"S/.1500 -\r\n S/.2500", "S/.500 -\r\n S/.1500", "S/.1500 -\r\n S/.2500", 
"S/.1500 -\r\n S/.2500", "S/.1500 -\r\n S/.2500"), descuento = c(-0.2002002002002, 
-0.285816362986781, -0.242571255306246, -0.150075037518759, -0.351446336847797, 
-0.214362272240086)), row.names = c(NA, 6L), class = "data.frame")

Answer 1

您可以使用tickprefix属性代替hoverformat：

plot_ly(mtcars, x = ~am, y = ~wt) %>%
  add_boxplot() %>%
  layout(yaxis = list( tickprefix = 'S/', tickformat = ',.2f' )) %>% 
  config(displayModeBar = FALSE) 

这还具有在Y轴刻度上显示的优点：
