CoreGraphicsGraph

Draw a line graph with CGPath and Swift. This is really just the result of playing with Swift, and so I can't garuntee the code is production ready, or even very good.

// GraphView.swift example usage

let myData = [
    ["Mon" : 15],
    ["Tues" : 30],
    ["Weds" : 7],
    ["Thurs" : 60],
    ["Fri" : 30],
    ["Sat" : 15],
    ["Sun" : 45]
]

let graph = GraphView(frame: CGRect(x: 50, y: 50, width: 420, height: 200), data: myData)
self.view.addSubview(graph)

Graph customisation options

There isn't really that many…

• showLines - whether or not to display lines from Y axis values
• showPoints - whether or not to display points on the line graph
• linesColor - The colour of Y axis lines if visible
• xAxisColor - The colour of the X axis
• yAxisColor - The colour of the X axis
• graphColor - The colour of the actual line graph and points
• labelFont - Axis label font
• labelColor - The colour of the axis labels
• originLabelText - Text placed origin point
• originLabelText - The colour of originLabelText
• xMargin - padding left of initial point and right of last point
