I work with devart productsof a Firebird DB when I insert a DataSource I never get the necessary fields to view
After setting the DataSource on the chart the series are aware of the selected tablename will not display the fields of the Datasource
I have retested this here with:
1) dataset + datasource on the form
2) make sure the dataset is active
3) open design time editor for the chart
4) in the pane's Database tab select the datasource
5) open the series editor and select the DB field in the Database tab with "Fieldname Value"
