How to create a bar chart using plotly in R?

Plotly in R is a package specifically designed to create highly-interactive and publication-quality charts. The chart can be created by using plot_ly function of the package and there are three main arguments of plot_ly defined as x, y, and type, where x refers to the X-axis, y refers to the Y-axis and type refers to the chart type but the axes values are stored in a data frame or itself a shared.


Loading plotly package:

> library(plotly)

Consider the below data frame:

Live Demo

> x<-c("A","B","C","D")
> count<-c(321,324,320,328)
> df<-data.frame(x,count)
> df


x count
1 A 321
2 B 324
3 C 320
4 D 328

Creating the bar plot for x:

> plot_ly(x=x,y=count,type='bar')


Warning message:

`arrange_()` is deprecated as of dplyr 0.7.0. Please use `arrange()` instead. See vignette('programming') for more help This warning is displayed once every 8 hours. Call `lifecycle::last_warnings()` to see where this warning was generated.

Here it is showing a warning but it is not related to our chart hence there is no problem in ignoring it.


If we want to create the chart with main title and axes titles then we need to store it in an object and then use the layout function as shown below:


> Bar<-plot_ly(x=x,y=count,type='bar')
> layout(Bar,title="Bar chart",xaxis=list(title="Groups"),yaxis=list(title="Count"))
