Solution 1

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

C#

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);

Solution 2

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.

You should not post a question as a "Solution". Either add a comment to a previous solution by pressing the "Have a Question or Comment?" button or post a new question. Posting a question in a solution, besides being bad form, can cause your question to be missed.

Solution 3

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[^].
