（void）createBurnoutChart {

    burnoutChart.titleLabel.font = [UIFont fontWithName:@"TrebuchetMS" size:27.0f];
} else {
    burnoutChart.titleLabel.font = [UIFont fontWithName:@"TrebuchetMS" size:17.0f];
}
burnoutChart.titleLabel.textColor = [UIColor whiteColor];


// If you have a trial version, you need to enter your licence key here:
//    chart.licenseKey = @"";

// Add the chart to the view controller
[self.viewBurnoutChart addSubview:burnoutChart];

}

//确保我们获取最新数据 NSInteger lastScore = [burnoutDatasource reReadData]; [self vasBurnoutImage：lastScore]; [self vasBurnoutScore：lastScore]; [burnoutChart reloadData]; [burnoutChart redrawChartAndGL：YES];

// *****重要的是重置可见部分..如果我得到了它 // [burnoutChart.xAxis resetZoomLevel]; }

图表显示效果很好，但是当涉及yAxis时，它会完全停在100限制范围内。我希望显示更多间隔，以便它看起来不会被切断。

Answer 1

有两种方法可以实现这一目标：

如果您想手动设置轴的范围（与当前一样），则只需增加范围，例如不应影响刻度标签。
如果您乐意让图表确定范围，那么您可以使用rangePaddingHigh属性来调整添加到计算范围内的填充量。

我希望有所帮助！
