it works. but, it's really slow. (FYI, I attached the C# code.)
Once query has been submitted, it usually give a 7000 rows of data (for one device). It should handle at least 10 devices at one graph. Our current 3rd party chart tool can handle the same amount of data in decent amount of time and query itself took less than sec. But, with RadChart, it takes upto 2mins.
We tested the same environment with current charting tool and radchart.One difference is that Radchart requires "foreach loop" of data to convert each datetime string althogh the other tool will take the datetime as it is (simply, binding it as table).
Can you suggest a better way to play with RadChart on datetime x-axis??
Since other features of telerik product is very attractive, I need to improve this if possible to allow us to use telerik as our next generation tool.
void initialDrawChart(RadChart radchart)
SqlDataAdapter adapter = new System.Data.SqlClient.SqlDataAdapter("SOME REQUEST",
DataSet zones = new DataSet();
ChartSeries s = radchart.Series;
foreach (DataRow row in zones.Tables.Rows)
ChartSeriesItem item = new ChartSeriesItem();
double temp = (double)row["VALUE"];
DateTime dt = (DateTime)row["DATE"];
item.YValue = temp;
item.XValue = dt.ToOADate();
