r - Names Argument Plotly Barplot -

so using plotly in shiny create bar chart. x labels not unique example (dog twice):

let df be:

x     y 1     dog 2     cat 3     dog 3     ant 4     bee 

i rows plotted won't work because of repeated variable dog in x column:

p = plot_ly(df, x = df[,2],  y = df[,1], type = "bar", marker = list(color = torgb("blue"))) p 

so thinking of getting past doing like: able plot 5 rows removing x argument. want able modify these names separately fill in x column variables.

p = plot_ly(df,  y = x, type = "bar", marker = list(color = torgb("blue"))) p 

how manually change x labels in plotly barplot?

thank you

straightforward official method:

use tickmode, tickvals, , ticktext arguments in layout xaxis:

library(plotly) plot_ly(df, y = x, type = "bar",          marker = list(color = torgb("blue"))) %>%           layout(xaxis = list(tickmode = "array",                              tickvals = 0:4,                              ticktext = c("dog", "cat", "dog", "ant", "bee"))) 

i not sure how y = x in above command generalize in other kinds of plots. hence, recommend approach:

# change y labels (i assigned "a", "b" etc.)  df$y <- letters[1:nrow(df)]   df %>% plot_ly(x = y,  y = x, type = "bar",                 marker = list(color = torgb("blue"))) %>%                 layout(xaxis = list(tickmode = "array",                                    tickvals = c("a", "b", "c", "d", "e"),                                    ticktext = c("dog", "cat", "dog", "ant", "bee"))) 

short hack:

just add whitespace @ end of second occurrence of dog:

df$y <- as.character(df$y) df[3,2] <- "dog " 

you can use first plot command:

plot_ly(df, x = df[,2],  y = df[,1], type = "bar", marker = list(color = torgb("blue"))) 

i checked plots both approaches, , same. obviously, real application might not simple , hack won't feasible.

plus, can use ggplot2 , make plots interactive plotly::ggplotly
