切片外部的饼图条目具有不同的位置偏移 [英] Pie Chart entries outside slices have different position offsets

问题描述

我正在使用的Charts库: Daniel Gindi-图表

The Charts library I'm using: Daniel Gindi - Charts

如果您查看上面的图像，则每个切片外部的条目的位置偏移在距切片的距离以及对齐方式上都是可变的.

If you look at the above image, the position offset of entries outside each slice are variable both in distance from the slice as well as in alignment.

我想要什么:

1. 将输入文本对齐到切片外部的中心.[看1&3]
2. 保留所有与切片等距的切片文本.[看3&6]

到目前为止我尝试过的事情:

What I tried so far:

我尝试使用 valueLinePart1Length 和 valueLinePart2Length ，但这只是有所帮助，并不能完全解决问题.我还浏览了 PieChartDataSet 的所有变量.

I tried to play with valueLinePart1Length and valueLinePart2Length, but this just helped a little, didn't solve the problem completely. Also I went through all the variables of PieChartDataSet.

仍未弄清楚如何解决此问题，有人可以指出我是否缺少某些东西或如何解决此问题.

Still haven't figured out how to fix this, can someone point out am I missing something or how to fix the issue.

添加了代码

let values: [Double] = [16, 6, 1, 3]
let chartEntries: [PieChartDataEntry] = pieChartEntries(for: values)
let pieChartDataSet = PieChartDataSet(values: chartEntries, label: nil)

pieChartDataSet.sliceSpace = 2
pieChartDataSet.colors = colors
pieChartDataSet.valueLineWidth = 0
pieChartDataSet.valueLinePart1Length = 0.4
pieChartDataSet.valueLinePart2Length = 0
pieChartDataSet.valueTextColor = .black
pieChartDataSet.yValuePosition = .outsideSlice
pieChartDataSet.valueLineVariableLength = false

let pieChartData = PieChartData(dataSet: pieChartDataSet)
pieChart.data = pieChartData

推荐答案

将yValuePosition更改为.insideSlice

change the yValuePosition to .insideSlice
