Line circle layer- circle appearing stretched out #327

Hi! As you can see below, I added code to generate circle found in BarsPlusMinusAndLinesExample. However, the circle doesn't appear circular as it should, but instead looks horizontally stretched out. Please refer to the code and screenshots below.

let circleViewGenerator = {(chartPointModel: ChartPointLayerModel, layer: ChartPointsLayer, chart: Chart) -> UIView? in let color = UIColor(red: 0.7, green: 0.7, blue: 0.7, alpha: 1) let screenLoc = CGPoint(x: chartPointModel.screenLoc.x.isNaN ? 50.0 : chartPointModel.screenLoc.x, y: chartPointModel.screenLoc.y) let circleView = ChartPointEllipseView(center: screenLoc, diameter: 6) circleView.animDuration = 0 circleView.fillColor = color return circleView }

    `let lineCirclesLayer = ChartPointsViewsLayer(xAxis: xAxisLayer.axis, yAxis: yAxisLayer.axis, chartPoints: chartPoints, viewGenerator: circleViewGenerator, displayDelay: 0, delayBetweenItems: 0.05)`

Any ideas how to fix this? Thank you!

Please read https://github.com/i-schuetz/SwiftCharts/wiki/View-hierarchy-and-transforms#chartpointsviewslayer-transform-modes and see examples where the circles are not scaled.
