Set hoverinfo text in plotly scatterplot - r

I create a basic scatterplot with plotly like the one below. The issue is that while I set specifically the text inside the hoverinfo the numeric values are displayed one more time- (20,56) -before the actual text- Team Pts:20 Fantasy Pts: 56 -that I wish to display. How can I delete them?
pts<-c(10,20,30)
npts<-c(24,56,78)
ex<-data.frame(pts,npts)
library(plotly)
p <- plot_ly(data = ex, x = ~pts, y = ~npts,
marker = list(size = 10,
color = 'white',
line = list(color = 'rgba(152, 0, 0, .8)',
width = 2))) %>%
add_trace(
text = ~paste("Team Pts: ", pts, '</br>Fantasy Pts:', npts),
hoverInfo='text'
)
p

One way of doing this is to add the text to each data point, by adding in a variable to the hovertemplate parameter.
I don't have a way to test this at the moment, but it should look something like this:
add_trace(
x = ~pts,
y = ~npts,
hovertemplate = paste('<i>Team points</i>: %{x}',
'<br><b>Fantasy Pts</b>: %{y}</br>',
)
)

You just misspelled the argument hoverInfo, which should be hoverinfo, so your plot used the default hoverinfo = "all". Also, replace </br> by <br> to display the hover text on two lines:
library(plotly)
ex <- data.frame(
pts = c(10, 20, 30),
npts = c(24, 56, 78)
)
plot_ly(data = ex,
type = "scatter",
mode = "markers",
x = ~pts,
y = ~npts,
text = ~paste("Team Pts: ", pts, '<br>Fantasy Pts:', npts),
hoverinfo = "text"
)

R Plotly how to link text to bubbles in order to remove it when click on legend

With plotly on R, I have a bubble scatter plot and I want to add black text on each bubble. I also have my bubbles colored following a column of my data frame (Type: Yes or No). On my legend, when I click on "Yes" it will remove the bubbles linked to "Yes" but the text is staying, even if I added a 'legendgroup=~Type' in both traces.
How can I remove the text linked to the bubble when the user click on the legend ?
It is possible but only if I set 'color = ~Type' in my text trace, but I want to keep the text in black.
Example :
df <- data.frame(Projet=c("A", "B", "C"), x=c(0.2, 0.4, 0.6), y=c(0.6, 0.5, 0.1), Size=c(2,5,8), Type=c("Yes", "Yes", "No"))
fig <- plot_ly(df, x = ~ x, y = ~y) %>%
add_trace(color = ~Type, size = ~Size,
type = 'scatter', mode = 'markers',
sizes = c(20, 80),
marker = list(symbol = 'circle', sizemode = 'diameter',line = list(width = 2, color = 'gray60')),
hovertext = ~paste('Projet:', Projet, '<br>Size (kE):', Size),
hoverinfo="text", legendgroup=~Type) %>%
add_trace(type="scatter", mode="text", text=~Projet, showlegend=F, legendgroup=~Type)
fig
Which gives :
And if I click on "Yes" in the legend :
=> I want to remove the "A" and "B" text in this case
Thanks !
When I looked at your Plotly object, you assigned three group names to the parameter legendgroup. The reason it worked in your initial call add_trace is that Plotly will split a trace by color. In your call for text, everything is the same color, so it didn't automatically split the trace.
In your call for the text, you need to add split to split the trace.

Type = c("Yes", "Yes", "No"))
fig <- plot_ly(df, x = ~ x, y = ~y) %>%
add_trace(color = ~Type, size = ~Size,
type = 'scatter', mode = 'markers',
sizes = c(20, 80),
marker = list(symbol = 'circle', sizemode = 'diameter',

add_trace(type = "scatter", mode = "text", text = ~Project,
showlegend = F, legendgroup = ~Type, split = ~Type) # <- I'm new!

Changing the color of a specific ring in a radar chart created in plotly

I have a radar chart created w/ plotly as shown below. Is there a way to have only the ring at 100 colored red, while all other rings remain in their off-gray color?
library(plotly)
fig <- plot_ly(
type = 'scatterpolar',
r = c(135, 75, 110),
theta = c('A','B','C'),
fill = 'toself'
)
fig %>%
layout(
polar = list(
radialaxis = list(
visible = T,
range = c(0, 150)
)
)
)
To my knowledge, there is not an option to use custom formatting on any axis line other than zero, so there may not actually be a "canonical" answer here that you're hoping for.
That being said, adding another trace to your plot might be the best work-around, even if it's a little clunky. Because the added line trace overrides the default categorical axis, some more extensive customization of the angular axis and some math to manually calculate categorical values relative to 360 degree coordinate system (this is normally obscured from the user) is required.
Names <- c('A','B','C')
Values <- c(135, 75, 110)
ThetaValues <- seq(from = 0, to = 360, length.out = length(Values)+1L)[seq_len(length(Values - 1L))]
plot_ly() %>%
add_trace(type = 'scatterpolar',mode = "lines",
r = rep(100,100),
theta = seq(from = 0, to = 360, length.out = 100),
line = list(smoothing = 1,
color = "red",
shape = "spline"),
hoverinfo = "skip",
showlegend = FALSE) %>%
add_trace(type = 'scatterpolar',mode = "markers",
r = Values,
name = "",
theta = ThetaValues,
color = I("blue"),
fill = 'toself') %>%
layout(polar = list(radialaxis = list(visible = T,
range = c(0, 150)),
angularaxis = list(visible = T,
type = "category",
ticktext = Names,
tickvals = ThetaValues)))

Create a filled area line plot with annotated scatters using plotly

I want to create a filled area plot with line and scatters like in the screenshot attached but I do not know how could add scatters for every year of x-axis and also annotate its value. My code is:
library(plotly)
data <- t(USPersonalExpenditure)
data <- data.frame("year"=rownames(data), data)
fig <- plot_ly(data, x = ~year, y = ~Food.and.Tobacco, name = 'Food and Tobacco', type = 'scatter', mode = 'line', stackgroup = 'one', fillcolor = '#F5FF8D')
fig
The mode lines+markers+text allows you to define a line plot with markers and add some text.
I changed the type of year from factor to numeric, because I had to expand the xaxis for readabilty of the annotations.
library(plotly)
data <- t(USPersonalExpenditure)
data <- data.frame("year" = as.numeric(rownames(data)), data)
plot_ly(data,
x = ~year,
y = ~Food.and.Tobacco,
text = ~Food.and.Tobacco) %>%
add_trace(
type = 'scatter',
mode = 'lines+markers+text',
fill = 'tozeroy',
fillcolor = '#F5FF8D',
marker = list(color = 'black'),
line = list(color = 'black'),
textposition = "top center",
hovertemplate = paste0("<b>%{x}</b>
Cummulative Food and Tobacco: %{y}
<extra></extra>"),
hoveron = 'points') %>%
layout(xaxis = list(
range= list(min(data$year) - 1, max(data$year) + 1)))

Add hoverinfo text on an added average line of plotly scatterplot

I create a basic plotly scatter plot with a line of average added. Is it possible to add hoverinfo text like: "Average : <Average Value>" ? Another solution would be the text to be permanently displayed over the line but I think that this might be more complex.
pts<-c(10,20,30)
npts<-c(24,56,78)
ex<-data.frame(pts,npts)
library(plotly)
p <- plot_ly(data = ex, x = ~pts, y = ~npts,
marker = list(size = 10,
color = 'white',
line = list(color = 'rgba(152, 0, 0, .8)',
width = 2))) %>%
add_segments(x = 0, xend = max(ex$pts), y = mean(ex$npts), yend =mean(ex$pts) )%>%
add_trace(
text = ~paste("Team Pts: ", pts, '</br>Fantasy Pts:', npts),
hoverInfo='text'
)
p

Viewing hover info for overlapping scatter points in Plotly R

I was surpised I was not able to google this solution, so I thought i'd put up a post. Surely others have the same issue...
The issue I have is that when two or more scatter points overlap (i.e. same x and y), the hover information only shows the info of the top point.
Example:
df <- data.frame(ID=1:6, x=c(5:9, 7), y=c(1:5, 3)+10, info=paste('Hover information: ',c(LETTERS[c(1:6)])))
df
plot_ly(df) %>%
add_trace(x = ~x,
y = ~y,
type = 'scatter',
mode = 'markers',
marker = list(color = 1:6,
symbol = 1:6,
size = 25),
hoverinfo = "text",
text = df$info)
It is possible to make BOTH hoverinfo for the middle point to show up? Possibly as:
Hover information: C
Hover information: F
You can try to use add_markers() and jitter, e.g:
plot_ly(df) %>%
add_markers(x = ~jitter(x, 1),
y = ~jitter(y, 1),
type = 'scatter',
mode = 'markers',
marker = list(color = 1:6,
symbol = 1:6,
size = 25),
hoverinfo = "text",
text = ~info)
But to get multiple information as you designed, maybe you need to modify your dataframe (but you will lose the colour code):
df$info <- as.character(df$info)
df$combined_info[1] <- df$info[1]
for(i in 2:nrow(df)){
df$combined_info[i] <- df$info[i]
for(j in 2:i-1){
if((df$x[j] == df$x[i]) && (df$y[j] == df$y[i])){
df$combined_info[i] <- paste0(df$combined_info[j], "<br>",
df$info[i])
}
}
}
And then you can use the original plotly code, while changing the "text" argument:
plot_ly(df) %>%
add_trace(x = ~x,
...
text = ~combined_info)
