Hi Experts!

I have a SharePoint list that contains (among other columns) a "Status" and "Discrepancy Value". Both are calculated columns. Example of the data is:

 sample data
I would like to plot a graph that will sum the "Discrepancy Value" column for each type of "Status". An example of the graph would be:

 Graph for sample data
I use Visifire graphs and SharePoint designer to usually plot graphs. Can you guys please assist?

Regards,
Kritesh.

What is the exact issue you are having? If you are having an issue with Visifire, I would suggest you contact them.

Hi.

No issue with Visifire. I would like to know how to do it because there is no clear option for it. It must be coded and i'm not sure how to do it.

Just to have a better understanding of the question what you need is just plot a graph using the data you have retrieved from Share point ?
Is it necessary that you need the graph in Visfire ?
I don't have much exp in MOSS and wont be able to help you in retrieving the data from there to SL but can help you with creating the graph in Silver light if you can get the data from MOSS

Also based on the assumption that we we not using Visfire  and you already have the data from Share point

data classes
public class SharepointData
    {
        public static ObservableCollection<Trans> GetData()
        {
            ObservableCollection<Trans> sales = new ObservableCollection<Trans>();

            sales.Add(new Trans() { DiscrepencyValue = 100, Status = "Completed" });
            sales.Add(new Trans() { DiscrepencyValue = 73, Status = "Waiting" });
            sales.Add(new Trans() { DiscrepencyValue = 12, Status = "Completed" });
            sales.Add(new Trans() { DiscrepencyValue = 24, Status = "OutStanding" });
            sales.Add(new Trans() { DiscrepencyValue = 22, Status = "Waiting" });
            sales.Add(new Trans() { DiscrepencyValue = 67, Status = "Waiting" });
            sales.Add(new Trans() { DiscrepencyValue = 9, Status = "OutStanding" });
            sales.Add(new Trans() { DiscrepencyValue = 59, Status = "Completed" });

            return sales;
        }
    }

    public class Trans
    {
        public string Status { get; set; }
        public int DiscrepencyValue { get; set; }
    }

Also the charting is done using Silverlight tool kit  which you can download from http://silverlight.codeplex.com/
Once you have downloaded this you need add references to the ToolKit dll to your project.
