Hello,
I would like to have information about the functionalities supported and performance of the WebCharts an WebGrid for VS 2005.
For the webchart we will use in particularly the LineChart (StepLine, StepArea,…).
In our project we have (huge data) every time at minimum 500000 records of data to generate a chart. I would like to know if your webchart (and webgrid) have a height performance when loading the data to the chart and generate it.
I would like to know how the webchart (and webgrid) is generated at client side and server side?
What is the difference between your webchart controls and the webchart controls of the Telerik and Dundas companies?
Thank you in advance.
it will take at least a few seconds each time you generate a chart with 500k points, unless you have a very powerful server.
the chart image is generated on the server using GDI+ and saved to an image. on the client, an ImageMap is generated with some javascript to show tooltips when you move the mouse around. if you have 500k points, though, you probably will want to turn the tooltips off so you don't end up with a giant imagemap in your HTML.
telerik's ASP.NET chart is a simpler control with far fewer features than infragistics or dundas. dundas has more features than our chart, but the custom drawing and manipulation of chart elements is limited compared to ours.
