自定义图例饼图怎么显示隐藏某一块？ #1550

Closed CoderLR closed 3 months ago

CoderLR commented 3 months ago

折线图可以使用aa_hideTheSeriesElementContentWithSeriesElementIndex、aa_showTheSeriesElementContentWithSeriesElementIndex来控制Series的显示和隐藏。 但是，饼图的话只有一个Series，请问我点击自定义的图例调用什么方法来显示和隐藏呢？

参考此次提交的内容:

关键内容为:

- (void)showOrHideDataPointOfSeriesElementWithDataPointIndex:(NSUInteger)dataPointIndex isVisible:(BOOL)isVisible {
    NSString *jsStr = [NSString stringWithFormat:@AAJSFunc(function showDataPoint(pointIndex, visibility) {
        let point = aaGlobalChart.series[0].data[pointIndex];
        point.setVisible(visibility);
    }

    showDataPoint(%tu, %u)), dataPointIndex, isVisible];

    [self.aaChartView evaluateJavaScript:jsStr completionHandler:^(id item, NSError * _Nullable error) {
        NSLog(@"%@",error);
    }];

    NSLog(@"隐藏或显示 dataPointIndex 值为 %tu", dataPointIndex);
}
