Scrollable-GraphViewを試してみる
swiftで滑らかなグラフが作成できるScrollable-GraphViewを試してみる。
Barチャートの作成は以下のようなコードで可能。
private func createDarkGraph(frame: CGRect) -> ScrollableGraphView { let graphView = ScrollableGraphView(frame: frame) graphView.backgroundFillColor = UIColor.colorFromHex("#333333") graphView.lineWidth = 1 graphView.lineColor = UIColor.colorFromHex("#777777") graphView.lineStyle = ScrollableGraphViewLineStyle.Smooth graphView.shouldFill = true graphView.fillType = ScrollableGraphViewFillType.Gradient graphView.fillColor = UIColor.colorFromHex("#555555") graphView.fillGradientType = ScrollableGraphViewGradientType.Linear graphView.fillGradientStartColor = UIColor.colorFromHex("#555555") graphView.fillGradientEndColor = UIColor.colorFromHex("#444444") graphView.dataPointSpacing = 80 graphView.dataPointSize = 2 graphView.dataPointFillColor = UIColor.whiteColor() graphView.referenceLineLabelFont = UIFont.boldSystemFontOfSize(8) graphView.referenceLineColor = UIColor.whiteColor().colorWithAlphaComponent(0.2) graphView.referenceLineLabelColor = UIColor.whiteColor() graphView.numberOfIntermediateReferenceLines = 5 graphView.dataPointLabelColor = UIColor.whiteColor().colorWithAlphaComponent(0.5) graphView.shouldAnimateOnStartup = true graphView.shouldAdaptRange = true graphView.adaptAnimationType = ScrollableGraphViewAnimationType.Elastic graphView.animationDuration = 1.5 graphView.rangeMax = 50 graphView.shouldRangeAlwaysStartAtZero = true return graphView }
