.net图表控制是否可以编辑 [英] can .net chart conrols be editable

问题描述

是否可以在运行时编辑图形?
我正在使用.net图表控件显示折线图.我还想在运行时向图中添加点并将其保存到sql server数据库中.有没有办法做到这一点?

是的，您可以在运行时将点添加到MS Chart控件.使用类似下面的代码.

  public 图表myChart；

// 初始化图表.... 

// 新数据
 double  newX =  20 . 0 ;
 double  newY =  10 . 25 ;

 int  currentSeries =  0 ; // 设置为要添加点的序列
myChart.Series [currentSeries] .Points.AddXY(newX，newY); 

是否有一个属性可以使用.net图表控件进行放大和缩小.只有Windows Forms控件可以启用缩放和滚动，而ASP.NET图表控件不支持缩放和滚动.
但是我正在使用webforms(System.Web.UI.DataVisualization.Charting).是否可以?如果需要代码plz.

回答解决方案2中的问题. MS图表控件允许对WinForms进行缩放和滚动，但对于ASP.NET则不允许进行缩放. 查看本文 [这些链接 [ ^ ]用于MS图表控件. DL特别适合您，并尝试在此处找到的ASP.NET示例 [ ^ ].

解决方案

Yes, you can add points to a MS Chart control at runtime. Use something like the following code.

public Chart myChart;

//initialize chart ....

//new data
double newX = 20.0;
double newY = 10.25;

int currentSeries = 0;//set to the series to which you want to add points
myChart.Series[currentSeries].Points.AddXY(newX , newY);

Is there a property to zoomin and zoomout using .net chart controls.I read some articles stating only Windows Forms control you can enable zooming and scrolling whereas ASP.NET chart control doesnt support zooming and scrolling.
But I am using webforms(System.Web.UI.DataVisualization.Charting).So is it possible?if so i need the code plz.

In answer to the question in Solution 2. The MS Chart Controls allow zooming and scrolling for WinForms, but not for ASP.NET; see this article[^].
Also, to learn more about MS Charts take a look at these links[^] for MS Chart Controls. You especially should DL and try out the ASP.NET samples found here[^].
