C# 图表混乱重设自动值时的缩放

我用一张图表来描绘传感器的一些信息。一切都很顺利，直到我达到3660分的间隔。 因此，我想做的是，当我的点达到该值时，我的图表将删除第一个点并添加新点，请查看代码：

if (graficoKVm.Series[0].Points.Count > 3660)
{
    graficoKVm.Series[0].Points.RemoveAt(0);
    graficoKVm.Series[0].Points.AddXY(DateTime.Now.ToOADate(), _sensorCampoEletroMagnetico.kVm);
    graficoKVm.ResetAutoValues();
}

问题是，如果图表被缩放，当它执行

graficoKVm.ResetAutoValues（）时我的变焦被搞砸了。
到目前为止，我试图存储缩放值，然后在重置后应用缩放，但我没有实现它。以下是图表声明：

您是否尝试在代码中使用
刷新
或
更新
？当索引达到3660时，图表将被替换为序列中保存的
点
，无论您应用了多大的缩放。
为了使其以正确的方式工作，我已完成以下实现：

if (graficoKVm.Series[0].Points.Count > 3659)
{
    graficoKVm.Series[0].Points.AddXY(DateTime.Now.ToOADate(), _sensorCampoEletroMagnetico.kVm);
    if (!graficoKVm.ChartAreas[0].AxisX.ScaleView.IsZoomed &&
        !graficoKVm.ChartAreas[0].AxisY.ScaleView.IsZoomed &&
        !graficoKVm.ChartAreas[0].AxisY2.ScaleView.IsZoomed &&
        !graficoKVm.ChartAreas[0].AxisX2.ScaleView.IsZoomed)
    {
        while (graficoKVm.Series[0].Points.Count > 3660)
        {
            graficoKVm.Series[0].Points.RemoveAt(0);
        }
        graficoKVm.ResetAutoValues();
    }
}

因此，如果图表在任何轴上缩放，它将不会重置每个轴的最小值和最大值。消除缩放问题。
嗯，也许我没有正确理解你的问题。为什么要使用ResetAutoValues？不，你是对的。这就是它所做的，但它只是使我的缩放到Y上的最小值和X上的最小值。我不知道，也许这是我的图表属性上的一些东西……我不认为这行代码会有那么大的帮助。如果删除该选项，则不应影响您的代码。是的，确实如此。对我的客户来说，这只关系到最后一个小时，所以我需要在图表上保持1小时+1分钟=（3660秒）。但我找到了答案。
