折磨我的mschart问题

aha100 2010-05-26 12:25:33

看下面的代码

private void ShowPoints()
{

//make the chart can scroll and zoom
Chart1.ChartAreas[0].CursorX.IsUserEnabled = true;
Chart1.ChartAreas[0].CursorX.IsUserSelectionEnabled = true;
Chart1.ChartAreas[0].CursorX.Interval = 1;
Chart1.ChartAreas[0].CursorX.IntervalType = DateTimeIntervalType.Days;//notice here
Chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
Chart1.ChartAreas[0].AxisX.ScrollBar.Enabled = true;
//Chart1.ChartAreas[0].AxisX.LabelStyle.Format = "HH:mm";

// Populate series data
double[] yValues = { 2.8684, 2.8994, 2.9252, 2.9557, 2.9714, 2.9136, 3.0097, 2.8994, 2.9854, 2.8993, 2.9646, 2.9140 };
DateTime currentDate = DateTime.Now;
Random random = new Random();
Chart1.Series["Series1"].Points.Clear();
for(int pointIndex = 0; pointIndex < 12; pointIndex++)
{
Chart1.Series["Series1"].Points.AddXY(currentDate, yValues[pointIndex]);
currentDate = currentDate.AddDays(random.Next(1, 5));//notice here

}

}

上面的代码工作正常，可以进行缩放并能拖动滚动条和scroll滚动条（就是滚动条可以拖动并且点击滚动条空白的地方也能移动滚动条。）但如果改成下面的代码，就不能拖动滚动条了，但点击空白的地方还是可以移动的。不知道是为什么，大家有什么办法可以解决吗。

private void ShowPoints()
{

//make the chart can scroll and zoom
Chart1.ChartAreas[0].CursorX.IsUserEnabled = true;
Chart1.ChartAreas[0].CursorX.IsUserSelectionEnabled = true;
Chart1.ChartAreas[0].CursorX.Interval = 1;
Chart1.ChartAreas[0].CursorX.IntervalType = DateTimeIntervalType.minutes;//变了，而且改成hours也一样
Chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
Chart1.ChartAreas[0].AxisX.ScrollBar.Enabled = true;
//Chart1.ChartAreas[0].AxisX.LabelStyle.Format = "HH:mm";

// Populate series data
double[] yValues = { 2.8684, 2.8994, 2.9252, 2.9557, 2.9714, 2.9136, 3.0097, 2.8994, 2.9854, 2.8993, 2.9646, 2.9140 };
DateTime currentDate = DateTime.Now;
Random random = new Random();
Chart1.Series["Series1"].Points.Clear();
for(int pointIndex = 0; pointIndex < 12; pointIndex++)
{
Chart1.Series["Series1"].Points.AddXY(currentDate, yValues[pointIndex]);
currentDate = currentDate.Addminutes(random.Next(1, 5));//变了，而且改成hours也一样

}

}

为什么我的mschart控件没curseX属性

好长时间了，回来结下帖子。
问题解决了，不过mschart真的是特别的东西，大家用的时候注意curseX的设置与scrollbar的设置还有axisX的设置要对应。
如有问题找我。
