Change plotly chart y variable based on selectInput

Question

I\'m creating a simple line chart which renders correctly in Shiny.

I\'ve now added a selectInput with the names of 2 different measures, written as they appear in m

Answer 1

Use base::get() function:

p <- plot_ly(data = data, x = ~Month, y = ~get(input$Measure), type = "line")

or the same using ggplot:

p <- ggplot(data = data, aes(x = Month, y = get(input$Measure))) +
geom_line(size = 1.5) + 
theme_minimal()
ggplotly(p)

Answer 2

Simply just use data[ ,input$Measure] as Your y variable:

p <- plot_ly(data = data, x= Month, y = data[ ,input$Measure], type = "line")
