Hi fellows plotly users.
I’m looking for a way to trace function directly from its equation.
It can be done with ggplot with the function stat_function.
I can easily compute the function statically, and then plot the result with a scatter plot:
suppressMessages(library(plotly))
a=2
b=3
myFunction <- function(x){
return (a*x+b)
}
myX <- seq(-25,15,0.1)
myY <-myFunction(myX)
fig <- plot_ly(
type = 'scatter',
mode = 'lines',
x = myX,
y = myY,
legendgroup = paste("MyFunction")
)
htmlwidgets::saveWidget( as_widget(fig), "MWELiveFunction.html");
But this solution is static and I would like to be able to modify on the go the function parameters (a and b) from buttons.
Any ideas on how I could manage to just trace the curve from the function equation ?
