Hi the hover text does not work in this script. Any idea ??
It should display the text withing the text variable below.

mm ← structure(list(Taxa = structure(1:13, .Label = c(“Streptococcus salivarius”,
“Lactobacillus gasseri”, “Escherichia coli”, “Shigella boydii”,
“Pseudomonas aeruginosa”, “Staphylococcus aureus”, “Enterococcus faecalis”,
“Staphylococcus epidermidis”, “Bacteroides vulgatus”, “Bacillus sp.”,
“Clostridium perfringens”, “Propionibacterium acnes”, “Bifidobacterium longum”
), class = “factor”), variable = structure(c(1L, 1L, 1L, 1L,
1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L), .Label = c(“Relative_abundance_median”,
“Relative_abundance_mean”), class = “factor”), value = c(6.77,
6.28, 13.76, 13.78, 7.25, 6.35, 6.82, 6.13, 6.36, 6.77, 5.34,
7.17, 7.2)), .Names = c(“Taxa”, “variable”, “value”), row.names = c(NA,
13L), class = “data.frame”)

col_vector1=c(“#76021F”, “#3BF13B”, “#69E4ED”, “#956FF5”, “#FCDA61”, “#075B0E”,

“#B36317”)

leg ← list(
bgcolor = “#EEE0E5”,
bordercolor = “#FFF0F5”,
borderwidth = 2
)
ang ← list(tickangle = 45)
mar ← list(
l = 50,
r = 50,
b = 120,
t = 50,
pad = 4,
autoexpand=T
)

                     Taxa                  variable value

Hi David, I know this is quite late, but you have misused the text argument here is the working code:

mm <- structure(list(Taxa = structure(1:13, .Label = c("Streptococcus salivarius", 
                                                       "Lactobacillus gasseri", "Escherichia coli", "Shigella boydii",

                       yaxis = list(title = "Percent abundance")
                )

I came across this because I have an issue with the hover text with scattermapbox. The key difference between the two is that one has specified hoverinfo = 'text' where as the other one does not specify this argument. When the argument is not specified the hover text doesnt show for all points. Any help?

Hi,
Thanks for the late update. In fact I could manage to fix it. Thanks anyway.
Regarding your info i would try the following since hoverinfo is a nightmare

# Let´s try to hack the code and see if it works. Once you have generated the Map_1 ,type the following:

Map_1 ← plotly_build(Map_1)$x
l ← length(Map_1$data)
for (i in 1:l)
{
Map_1$data[[i]]$hoverinfo ← NULL
}
Map_1 ← as_widget(Map_1)
Map_1

Works well for me.

Hi David,

I can get the same result by not specifying the hoverinfo argument, no hacking required. The challenge is that I don’t want to see the longitude and latitude of the points, as it is not really relevant.

According to the documentation, you can do this by specifying hoverinfo = 'text' although this is not working, FYI this used to work in a previous version of the shiny app, it seems that I have introduced a bug somewhere but I cant determine where.

Hello, were you able to find a workaround to this? I am unable to get the hover feature to work in the Plotly code on the website for Scatter Plots on Maps. This code only plots the markers with no hover functionality. Thanks,

library(plotly)
df <- read.csv(‘https://raw.githubusercontent.com/plotly/datasets/master/2011_february_us_airport_traffic.csv’)

geo styling

g <- list(
scope = ‘usa’,
projection = list(type = ‘albers usa’),
showland = TRUE,
landcolor = toRGB(“gray95”),
subunitcolor = toRGB(“gray85”),
countrycolor = toRGB(“gray85”),
countrywidth = 0.5,
subunitwidth = 0.5
)

p <- plot_geo(df, lat = ~lat, lon = ~long) %>%
add_markers(
text = ~paste(airport, city, state, paste(“Arrivals:”, cnt), sep = “
”),
color = ~cnt, symbol = I(“square”), size = I(8), hoverinfo = “text”
) %>%
colorbar(title = “Incoming flights
February 2011”) %>%
layout(
title = ‘Most trafficked US airports
(Hover for airport)’, geo = g
)

Hey @neel123

It looks like there may be an issue with hoverinfo and plot_geo. I’ve opened an issue here https://github.com/ropensci/plotly/issues/1127
