Shade the area with shading lines
Under this method, we are using the density and the angle argument of the polygon function where the density is responsible for the number of lines per unit area and the angle in the angle at which the line is to be drawn.
Example:
In this example, we are creating a line plot in the shape of t of the rectangle and with the use of the density and angle argument of the polygon function, we are shading a line of green color within the line rectangle plot.
R
# Grid of X-axis values x <- seq(0, 10, 0.01) # Data y1 <- sin(x) + 8 y2 <- 2* sin(x) + 4 # Lines plot(x, y1, type = "l", ylim = c(1, 10), ylab = "y") lines(x, y2, col = 2) # Fill area between lines polygon(c(x, rev(x)), c(y2, rev(y1)), col = "darkgreen",density = 10, angle = 45) |
