How to create a stacked bar chart using plotly in R? Bar charts are a graphical representation of a categorical or discrete type of data. The data is represented in the form of rectangular bars either horizontally or vertically on the graph. Stacked bar charts are an extension of a bar chart that represents the part of a whole type of data comparison of given categories. This recipe demonstrates an example of stacked bar chart in R.
Step 1 - Install the necessary package and library
install.packages("plotly")
library(plotly)
Step 2 - Define a Vector
data <- data.frame(x_val = c(10,5,6,15,20,19),
y_val = c(2,12,19,11,6,14),
type = c("A","B","C","D","E","F"))
data
"Data :" label1 label2 value X X1 10 X X2 20 X X3 30 Y Y1 40 Y Y2 50
Step 3 - Plot a stacked bar chart
Syntax for line chart using plotly - plot_ly(x, type, mode) where, x - input data type - bar mode - lines
figure <- plot_ly(data, x = ~type, y = ~x_val, type = 'bar', name = 'X')
figure <- figure %>% add_trace(y = ~y_val, name = 'Y')
figure <- figure %>% layout(yaxis = list(title = 'Count'), barmode = 'stack')
figure
