Changing bar plot orientation
library(plotly)
g <- ggplot(mpg, aes(class))
p <- ggplot(mpg) + geom_bar(aes(y = class))
ggplotly(p)
Stacking bar plots
Bar plots are automatically stacked when multiple bars are at the same location. The order of the fill is designed to match the legend.
To flip the order (because you've flipped the orientation) call position_stack()
explicitly.
library(plotly)
g <- ggplot(mpg, aes(class))
p <-
ggplot(mpg, aes(y = class)) +
geom_bar(aes(fill = drv), position = position_stack(reverse = TRUE)) +
theme(legend.position = "top")
ggplotly(p)
What About Dash?
Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.
Learn about how to install Dash for R at https://dashr.plot.ly/installation.
Everywhere in this page that you see fig
, you can display the same figure in a Dash for R application by passing it to the figure
argument of the Graph
component from the built-in dashCoreComponents
package like this:
library(plotly)
fig <- plot_ly()
# fig <- fig %>% add_trace( ... )
# fig <- fig %>% layout( ... )
library(dash)
library(dashCoreComponents)
library(dashHtmlComponents)
app <- Dash$new()
app$layout(
htmlDiv(
list(
dccGraph(figure=fig)
)
)
)
app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
