Shinobi限制轴范围值iOS图表

我使用Shinobi iOS控件在我的应用程序中绘制折线图。我目前正在渲染一个严重的0值。结果图是这样的：Shinobi限制轴范围值iOS图表

enter image description here

现在的问题是，我代表数量的货币，因此不能为负数。在这种特定情况下，我如何限制范围从0开始？

这是如何创建的图形：

// initiatialise line chart 
    ShinobiChart *chartView = [[ShinobiChart alloc]initWithFrame:frame]; 
    chartView.clipsToBounds = NO; 
    //Choose the light theme for this chart 
    SChartLightTheme *theme = [SChartLightTheme new]; 
    //perform any theme stylign here before applying to the chart 
    chartView.theme = theme; 
    chartView.title = @"my Title"; 
    chartView.autoresizingMask = UIViewAutoresizingNone; 
    // Use a number axis for the x axis. 
    SChartDateTimeAxis *xAxis = [[SChartDateTimeAxis alloc] init]; 
    xAxis.title = @"date"; 
    xAxis.tickLabelClippingModeHigh = SChartTickLabelClippingModeTicksAndLabelsPersist; 
//keep tick marks at the right end 
    //Make some space at the axis limits to prevent clipping of the datapoints 
    xAxis.rangePaddingHigh = [SChartDateFrequency dateFrequencyWithDay:1]; 
    xAxis.rangePaddingLow = [SChartDateFrequency dateFrequencyWithDay:1]; 
    //allow zooming and panning 
    xAxis.enableGesturePanning = YES; 
    xAxis.enableGestureZooming = YES; 
    xAxis.enableMomentumPanning = YES; 
    xAxis.enableMomentumZooming = YES; 
    chartView.xAxis = xAxis; 
    // Use a number axis for the y axis. 
    SChartNumberAxis *yAxis = [[SChartNumberAxis alloc] init]; 
    yAxis.title = @"Value"; 
    yAxis.enableGesturePanning = YES; 
    yAxis.enableGestureZooming = YES; 
    yAxis.enableMomentumPanning = YES; 
    yAxis.enableMomentumZooming = YES; 
    yAxis.title = @"Value"; 
    yAxis.style.titleStyle.position = SChartTitlePositionBottomOrLeft; 
    chartView.yAxis = yAxis; 
    chartView.userInteractionEnabled = YES; 
    chartView.gesturePanType = SChartGesturePanTypeNone;

我使用了一个简单的ShinobiChart子类。通常范围始终在最低和最高值之间。现在图表反应是这样的，因为在这种情况下没有提供极端值，但我更愿意将最低极值设置为0. – Claus

您是对的......完成:) – Claus

当您初始化yAxis SChartNumberAxis时可以尝试使用具有适当SChartNumberRange的initWithRange：instance方法。 –

yAxis.anchorPoint = @ 0;

设置此，它应该解决您的问题。
