interact_zoom() with interact_brush() not working?
I'm very excited for this package! It seems like a very elegant syntax and I see lots of potential. I tried extending one of the Shiny examples by adding a simple zoom capability along with a brush (thinking it would work similar to how shiny lets you interact with ggplot2 plots). I thought I could use the brush to select a region and either use the mouse or double-click to zoom in to the region, but the plot dimensions stays the same. Perhaps I missed some parameters? Here's the simple app I tried:
library(g2r)
library(shiny)
ui <- fluidPage(
actionButton("hide", "hide"),
actionButton("show", "show"),
g2Output("chart")
)
server <- function(input, output) {
output$chart <- renderG2({
g2(cars, asp(speed, dist)) %>%
fig_point() %>%
fig_line() %>%
interact_brush() %>%
interact_zoom()
})
observeEvent(input$hide, {
g2Proxy("chart") %>%
conceal()
})
observeEvent(input$show, {
g2Proxy("chart") %>%
reveal()
})
}
shinyApp(ui, server)

Hi Eric,
Sorry for the late response. The brush is indeed not working, I'll look into that!
Thanks for reporting it, and thanks for the Shiny series too :smiley:
