  1. you can decrease the distance between DataLabels and pie

  2. you can change the lines of DataLabels from one line to multiline

For example

1. configure AAChartModel

    AAChartModel configurePieChart() {
      return new AAChartModel()
              .chartType(AAChartType.Pie)
              .backgroundColor("#ffffff")
              .title("LANGUAGE MARKET SHARES JANUARY,2020 TO MAY")
              .subtitle("virtual data")
              .dataLabelsEnabled(true)//是否直接显示扇形图数据
              .yAxisTitle("℃")
              .series(new AAPie[] {
                      new AAPie()
                              .name("Language market shares")
                              .innerSize("20%")
                              .size(150f)
                              .dataLabels(new AADataLabels()
                                      .enabled(true)
                                      .useHTML(true)
                                      .distance(5f)
                                      .format("<b>{point.name}</b>: <br> {point.percentage:.1f} %"))
                              .data(new Object[][] {
                              {"Java"  ,67},
                              {"Swift",999},
                              {"Python",83},
                              {"OC"    ,11},
                              {"Go"    ,30},
                      })
                      ,
                      }
              );
    }

The key code is

.dataLabels(
new AADataLabels()
            .enabled(true)
            .useHTML(true)
            .distance(5f)
            .format("<b>{point.name}</b>: <br> {point.percentage:.1f} %")
)
