Extra (unwanted) geoms in the legend

[yankev]

The code:

library(plotly)

dat1 <- data.frame(
  sex = factor(c("Female","Female","Male","Male")),
  time = factor(c("Lunch","Dinner","Lunch","Dinner"), levels=c("Lunch","Dinner")),
  total_bill = c(13.53, 16.81, 16.24, 17.42)
)

ggplot(data=dat1, aes(x=time, y=total_bill, group=sex, shape=sex, colour=sex)) +
  geom_line(aes(linetype=sex), size=1) +     # Set linetype by sex
  geom_point(size=5) +         # Use larger points, fill with white
  scale_colour_hue(name="Sex",      # Set legend title
                   l=30)  +                  # Use darker colors (lightness=30)
  scale_shape_manual(name="Sex",
                     values=c(22,21)) +      # Use points with a fill color
  scale_linetype_discrete(name="Sex") +
  xlab("Time of day") + ylab("Total bill") + # Set axis labels
  ggtitle("Average bill for 2 people") +     # Set title
  theme_bw()

This was already described in
#571

but probably deserves its own post...

Actually, these traces should be getting merged to produce 2 legend entries instead of 4, so I'd consider this a bug

[laoyang945]

same here, but one more bug imo

It's different of the "compare data on hover" command compared my version and the one on the plotly website. For my own version, all tooltips duplicate since it's a geom_line+geom_point. If I only use the geom_line, everything is fine.

[benjaminrobinson]

Any progress on this? Just wondering. Thanks for the great package! I tried adding a "show.legend = FALSE" to the geom I was trying to hide, which worked in my ggplot2 call but not in my ggplotly call.

[laoyang945]

@benjaminrobinson for my own case, I hacked the ggplotly object, deleting those I don't want

[benjaminrobinson]

@laoyang945 What about hacking on this type of issue to merge the legends for a line and point together or maybe only showing one?

Use aes outside the geom call to remove the extra unwanted legend in ggplotly. Consider, the basic graph p<- ggplot(df, aes(x = x, y = y)) + geom_point(aes(color=factor(z)), show.legend=FALSE), where df <- data.frame( x = 1:8, y=1:16, z = LETTERS[1:4]). Then define, p1 <- p + geom_line(aes(color=factor(z), linetype=factor(z))) and p2 <- p + geom_line(aes(color=factor(z) )) + aes(linetype=factor(z))
Please note that ggplotly(p1) gives two legends, while ggplotly(p2) gives one legend. Perhaps this solution is well known already. I could not find a solution easily. I hope this helps someone else encountering this issue.

[WhyBeeYes]

In R Shiny, use plotly_json()/style() to suppress unwanted legends as mentioned in #842. In the above example, define p3<- ggplotly(p1), and then p4 <- p3 %>% style(p3, showlegend = FALSE, traces = 1:n) ## where n = length(unique(df$z)) To suppress all legends, just use hide_legend. Please note that in R Shiny, ggplotly(p2) above will merge the legends for line and point together.

Hi WhyBeeYes, can you help me to apply your method to my case, plot is ok, ggploty has double legend, I want to remove the line legend:

df <- data.frame( x = 1:8, y=1:16, z = LETTERS[1:4])
q<- ggplot(df, aes(x = x, y = y)) + geom_point(aes(group=z, color=z, shape=z)) + geom_line(aes(group=z,color=z))
plot(q)
ggplotly(q)

found:
q<- ggplot(df, aes(x = x, y = y)) + geom_point() + geom_line() + aes(group=z, color=z, shape=z)

[WhyBeeYes]

You can delete the unwanted legends as shown below

df <- data.frame( x = 1:8, y=1:16, z = LETTERS[1:4])
q <- ggplot(df, aes(x = x, y = y, group=z)) + geom_point(aes(shape=z)) + geom_line()  + aes(color=z)
p <- ggplotly(q)
qq <- p %>% style(p, showlegend = FALSE, traces = 5:8)

[tlorusso]

To remove redundant tooltips / hovers just use the hoverinfo argument.

p %>% style(hoverinfo = "none", traces = 1:2)
