作者你好， 当数据源数据都为0的时候： @[ @[@"AAAA", @(0)], @[@"BBBB", @(0)], @[@"CCCC", @(0)], @[@"DDDD", @(0)], @[@"EEEE", @(0)] ]; ，应该显示五等分吧 image

报错信息： image 有没有什么办法可以处理这种情况

参考:

OC 版本的配置方式如下:

//https://github.com/AAChartModel/AAChartKit/issues/1042
- (AAOptions *)makePieChartShow0Data {
    return AAOptions.new
    .titleSet((id)NSNull.null)
    .chartSet(AAChart.new
              .typeSet(AAChartTypePie))
    .seriesSet(@[
        AASeriesElement.new
        .nameSet(@"ZeroDataPie")
        .dataSet(@[
            @{@"y":@1, @"isZero":@true, @"name": @"One"  },
            @{@"y":@1, @"isZero":@true, @"name": @"Two"  },
            @{@"y":@1, @"isZero":@true, @"name": @"Three"}
                 ])
        .tooltipSet(AATooltip.new
                    .sharedSet(false)
                    .pointFormatterSet(@AAJSFunc(
        function() {
            return "<span style=\'color:" + this.color + "\'> ◉ </span>"
            + this.series.name
            + ": <b>"
            + (this.options.isZero ? 0 : this.y)
            + "</b><br/>";
        })))
               ])
    ;
}

demo 中有此示例, 下载运行查看即可.
