@maheshbapathi,

Please take a look at this sample project in ASP.Net MVC which updates chart data every 2seconds (which can be changed as per your requirements) by reading data from database.

Hello,
I have tried your example again there should be some bugs
If i try to change the any value on database which i have already created is not updating on graph and in the same way delete also not working
For example in database we have 2 columns x and y
x y
1 10
2 20
If i need change
x y
1 20
2 30
In the same way delete also
x y
1 20
If i can delete row 2
In these both scenarios graph is not updating.
let me know the reason why this was not updating

The sample project that you have shared is not working as it doesn’t include all dependency files. However when I looked into view (index.cshtml), you seemed to be creating new chart instance on every update. I would suggest you to create chart instance once and update dataPoints on every update and re-render the chart.

I have tried your example again there should be some bugs

While updating chart dataPoints, you can empty dataPoints array and update it according to the updated data which you receive from database as shown in this updated sample project.
