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 = [
    ["label" : "Mon",   "value" : NSNumber(int:15)],
    ["label" : "Tues",  "value" : NSNumber(int:30)],
    ["label" : "Weds",  "value" : NSNumber(int:7)],
    ["label" : "Thurs", "value" : NSNumber(int:60)],
    ["label" : "Fri",   "value" : NSNumber(int:30)],
    ["label" : "Sat",   "value" : NSNumber(int:15)],
    ["label" : "Sun",   "value" : NSNumber(int:45)],
] as NSArray

let graph = GraphView(frame: CGRectMake(50, 50, 420, 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
