Pie Chart showing user variables

Hi, I have a report where I have declared a bunch of uservariables with various calculations. I am trying to display these variables in a Pie Chart, is this possible? I can’t seem to figure out how to do this?

kind regards,
Bjørn

Dear Bjørn,

thank you for your post.

Unfortunately, your requirements can currently not be realized. The reason for this is that a pie chart is always bound to a table in the data source and the individual segments of a pie chart are calculated by an aggregate function from this data. We’d suggest to add a meta table to your data source that contains the effective results of your user variables. This way, you can bind to this meta table and get the required result. A schematic example:

[code]object ChartValue
{
Name {get;set}
Value {get;set}
}

ListmetaTable = new List{ … } // the values go in here

DataProviderCollection coll = new DataProviderCollection();
coll.Add();
coll.Add(new ObjectDataProvider(metaTable));

LL.DataSource = coll;
LL.Design();[/code]
Then bind the chart to the meta table and choose “Name” for the x- and “Value” for the y-axis.
