问题 I want to show the arrow of the maximum and minimum value just like the picture below. Does anyone have ideas about how to achieve it using iOS-Charts? Thanks a lot. 回答1: You need to write your own custom renderer for CandleStickChartView . Fortunately, in your case you need overwrite only one method. So, inherit class from CandleStickChartRenderer and override method drawValues(context: CGContext) . You can just copy/paste most of the code from parent's method and make only necessary changes

问题 I am using iOS Charts with Swift 3, and I can't figure out how to do a couple things: I want to remove the margin around the chart. I know the chart goes edge-to-edge in my UI because if I change the chart's background color, it goes all the way to the edge. How do I remove the gap indicated by the red arrows below? How do I remove the border around the whole graph (note the black arrow)? I already have totalsGraph.drawBordersEnabled = false and it doesn't work. Is there a different option

问题 I've created a BarChart using BarChartView from ios-Charts but I can't figure out howto add rounded corners to bars. This is the code that I'm using: let barChart: BarChartView //... var xVals = [String]() var yVals = [BarChartDataEntry]() //... let set1 = BarChartDataSet(yVals: yVals, label: "Label") set1.drawValuesEnabled = false set1.highlightLineWidth = 3 set1.colors = [UIColor.whiteColor()] barChart.data = BarChartData(xVals: xVals, dataSet: set1) I've looked for a property like set1

问题 I'm trying out a few things with the iOS Charts library with Swift 3.0. I have a question about formatting of the lineChartDataset values (displayed above each value point).

Any help would be appreciated. 回答1: ios-charts have been upgraded to protocol base approach for rendering the various kind of labels like
