My problem is that i can select only one colum as data source and title.
It does sound like you have used fields (columns) where you should have used records in your basic table design. A related set of records with one record for each type of work would be much easier to chart.
But are you trying to chart all the data from a single record or a group of records? There's a fairly simple way to chart the data if all the data is contained in the fields of your single record: Use the calculation option and specify: List ( field1 ; field 2 ; field 3 ...) as the source of data for your wedges. Use List ( "Field name 1" ; "Field Name 2 ; ...) as the source of data for your wedge labels. Specify "delimited data" as your data source for the chart.
