iOS图表-ScatterCart形状在缩放/滚动时消失

Question

我试图将散点图重新用作时间线.....

当我放大或缩小或滚动时，形状消失。

我已经分叉了图表仓库并更改了散点图数据以重现此问题：https://github.com/JayGoTenna/Charts

OR

您只需在ScatterChartViewController.m中将setDataCount更改如下：

- (void)setDataCount:(int)count range:(double)range
{
    NSMutableArray *yVals1 = [[NSMutableArray alloc] init];

    for (int i = 0; i < count; i++)
    {
        double val = (double) (arc4random_uniform(range)) + 3;
        [yVals1 addObject:[[ChartDataEntry alloc] initWithX:val y:1]];
    }

    ScatterChartDataSet *set1 = [[ScatterChartDataSet alloc] initWithValues:yVals1 label:@"DS 1"];
    [set1 setScatterShape:ScatterShapeSquare];
    [set1 setColor:ChartColorTemplates.colorful[0]];

    set1.scatterShapeSize = 8.0;

    NSMutableArray *dataSets = [[NSMutableArray alloc] init];
    [dataSets addObject:set1];

    ScatterChartData *data = [[ScatterChartData alloc] initWithDataSets:dataSets];
    [data setValueFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:7.f]];

    _chartView.data = data;
}

现在，当您放大或滚动图表时，您会发现形状消失了.....

还有其他人看到过吗？
