Inserting a Line into a Julia Set Image
Code
using Plots
scatter(rand(100), randn(100))
plot!([0,1],[0,1])
png("example1")
plot!([.00,.25,.50],[-2,0,-2])
png("example2")
θ = 0:0.01:2π
plot!(.5 .+ cos.(θ)/3, 1.5sin.(θ))
png("example3")
Let’s learn how to insert line segments into the diagram by executing the code above.
Line Segment plot!([0,1],[0,1])
Whether you draw just one line segment or something else, the method is the same. For a line segment, you need two points, so you just need to give an array of x
coordinates and an array of y
coordinates.
Multiple Line Segments plot!([.00,.25,.50],[-2,0,-2])
y3
draws two line segments at once. The start and end points of the segments are connected.
Ellipse plot!(.5 .+ cos.(θ)/3, 1.5sin.(θ))
By applying the method used to draw multiple line segments, you can also draw an ellipse. Both grammatically and computationally, it’s relatively easier to draw compared to other languages.
