Shinobi图表甜甜圈系列：如何改变drawDirection？

Question

我想在圆环图中更改drawDirection属性

请参阅：https://www.shinobicontrols.com/docs/ShinobiControls/ShinobiCharts/2.8.7/Standard/Normal/html/Classes/SChartDonutSeries.html

这是我所指的代码的一部分：

typedef NS_ENUM(NSInteger, SChartRadialSeriesDrawDirection) {
    SChartRadialSeriesDrawDirectionAntiClockwise,
    SChartRadialSeriesDrawDirectionClockwise
};

@interface SChartDonutSeries : SChartRadialSeries
#pragma mark -
#pragma mark Drawing the series
/** @name Drawing the series */

/** The direction in which data is drawn around the centre of the plot.

 - SChartRadialSeriesDrawDirectionClockwise: Configures the direction in which the data is drawn around the center of the plot to be clockwise.
 - SChartRadialSeriesDrawDirectionAntiClockwise: Configures the direction in which the data is drawn around the center of the plot to be anticlockwise.

 This defaults to `SChartRadialSeriesDrawDirectionAntiClockwise`.
 */
@property (nonatomic) SChartRadialSeriesDrawDirection drawDirection;
@end

这是我的代码：

let donutSeries = SChartDonutSeries()
donutSeries.drawDirection = SChartRadialSeriesDrawDirection.SChartRadialSeriesDrawDirectionClockwise

我怎样才能在swift 3中做到这一点？

Answer 1

免责声明我是ShinobiControls的开发人员。

您可以使用以下代码在Swift 3中设置饼图或甜甜圈系列的绘制方向：

pieSeries.drawDirection = .clockwise

确保您使用的是我们框架的最新版本（目前为2.9.3）。

如果您有任何问题，请与我们联系。

Answer 2

我发现我可以这样设置：

donutSeries.drawDirection = SChartRadialSeriesDrawDirection(rawValue: 1)!

如果有更好的方法，请告诉我。
