如何绘制这种图

plot(0, xlab = "Explanatory Variable X", ylab = "Probablity",
      main = "Logistic Regression Model", xlim = c(0, 2500),
      ylim = c(0,1), type = "n")
points(seq(0,2500,length.out = 401), y, cex=0.5, pch ="|", col="orange")
lines(seq(0,2500,length.out = 401), exp(x)/(1+exp(x)), lwd = 3, col = "lightblue")
