Hello! In my Shiny app, the user hits an action button (input$run) and that initiates the following section on server side: main_reactive <- reactiveValues() observeEvent(input$run, { ... a lot of different calculations ... main_reactive$forplot = mydataframe }) Once the calculations in this…

Or should I just move my renderPlot inside my observeEvent?

Hi! I don't know if you've tried using req(input$run) instead of the if statement? http://shiny.rstudio.com/reference/shiny/latest/req.html req() worked for me with a file upload input and a DT table output :slight_smile: Edit: I think you can actually use req(main_reactive$forplot)..
