I implemented followings.

func plot(_ x: [Double], _ y: [Double])
func scatter(_ x: [Double], _ y: [Double])
func hold(f: () throws -> Void) rethrows

and backward compatibility are presented with below.

public func addLine(
    x: [Double], y: [Double])
{
    hold {
        plot(x, y)
    }
}

public func addLine2(
    x: [Double], y: [Double],
    x2: [Double], y2: [Double])
{
    hold {
        plot(x, y)
        scatter(x2, y2)
    }
}

it tells API clearly for us.

After update Contents.swift(preinstalled presentation example code in book), I remove addLine and addLine2.

Ofcourse, if you call plot directly, it runs as hold { plot(x, y) }.
