我正在尝试通过am4chart库构建一个图表,它是一个每秒更新其数据集的实时图表。在值轴上有一个滚动条,用于操作图表的缩放级别。但当数据集更新时,图表会自动返回到最大缩放级别。 日期轴做得很好,一旦我移动水平滚动条,图表就会保持它的位置,如果我想让垂直滚动条以同样的方式执行,我应该如何修复它。 var newTemp = function(){
let timestamp = new Date();
let sensor1 = Math.random() * 10 + 20;
let sensor2 = Math.random() * 10 + 25;

我对Amcharts中的Hover Box有一些疑问。我只想更改鼠标悬停框的颜色。有没有人能帮我这个忙。当我去酒吧时,我在If else语句中设置的颜色总是出现。但我希望我总是在悬停时将蓝色设置为背景色(见附件)。我到底做错了什么? enter image description here var columnSeries = new am4charts.ColumnSeries();
columnSeries.name = "Pegelstand";
columnSeries.dataFields.valueY = "
使用来自LineGraph演示区的amCharts示例,我想隐藏Y轴标签。我尝试过许多老版本的东西,但没有取得任何成功。

我正在使用MahApps,并试图使它的重音颜色自动应用于OxyPlot图表。我以编程方式在视图模型中使用LineSeries并将其设置为:
_bubbleSeries = new LineSeries
{
StrokeThickness = 2,
Color = {Binding AccentColorBrush} // <-- This line here would be nice
CanTrackerInterpolatePoints = false,
Title = "Bubbles",
Smooth = true,
};
我正在制作一个应用程序,出现与经度,纬度,高度和速度。
每当我运行应用程序时: 1.标签| 2中没有显示位置数据。我收到以下错误消息:
fatal error: unexpectedly found nil while unwrapping an Optional value
我做错了什么?谢谢!
