我想用MSDN图表来表示的实时数据。我现在是远程登录应用程序获得。出于测试目的,我添加了一个按钮,手动更改图表。我手工制作图表,它与上X.该系列产品是由它命名的值不同的值X轴0到5分的默认系列1。
I want to use MSDN charts to represent realtime data i'm getting from a telnet application. For testing purpose i have added a button to alter the chart manually. I manually made the chart and it has 0 to 5 points on the X axis with values different values on the X. The series is named by it's default "Series1".
我试过如下:
chart1.Series [系列1] Points.ElementAt(0).SetValueY(40); //什么也没有发生。
chart1.Series["Series1"].Points.ElementAt(0).SetValueY(40); //Nothing happens
chart1.Series [系列1] Points.ElementAt(1).SetValueXY(1,20); //什么也没有发生。
chart1.Series["Series1"].Points.ElementAt(1).SetValueXY(1, 20); //Nothing happens
chart1.Series [系列1]点[0] .SetValueY(40)。 //什么也没有发生。
chart1.Series["Series1"].Points[0].SetValueY(40); //Nothing happens
chart1.Series [系列1] Points.ElementAt(1).YValues.SetValue(10,0); //什么也没有发生。
chart1.Series["Series1"].Points.ElementAt(1).YValues.SetValue(10, 0); //Nothing happens
chart1.Series [系列1] Points.Clear()。 //删除所有点像它应该。
chart1.Series["Series1"].Points.Clear(); //Removes all points like it should.
让我怎么改变运行数据点条目?
So how do i change datapoint entries on runtime?
-EDIT- 。如果我使用 chart1.Series [系列1]修改点Points.ElementAt(0).SetValueY(40); 并在此之后添加点与 chart1.Series [系列1] Points.AddXY(1,40); 修改后的点也扣入它的修改地点。结论是,改性不改变它的点的Y值,但图中没有得到刷新。该功能AddXY()似乎自动刷新。我似乎无法找到一个方法来手动调用刷新()。
-EDIT- If i modify a point using chart1.Series["Series1"].Points.ElementAt(0).SetValueY(40); and add a point after this with chart1.Series["Series1"].Points.AddXY(1, 40); the modified point does snap into it's modified place. The conclusion is that modifying does change the points Y value but the graph does not get refreshed. The function AddXY() seems to autorefresh. I cannot seem to find a way to call Refresh() manually.
推荐答案呼叫 chart1.Refresh( )修改完毕;这将迫使图表重绘,拿起新的值。
Call chart1.Refresh() after changing the value; it will force a redraw of the chart, picking up the new values.
