Query Editor Dialog
The Query Editor Dialog is used to create and edit SQL queries and expressions for use in Graphs. The dialog is always launched from the Graph Settings Dialog by clicking on the Query Editor button.
The editor is fairly self explanatory. You set up SQL like expressions using the Field list and the various operation buttons. Values to test against should be typed in manually. You can, if you wish, type entire expressions into the Expression box.
Use the Test button to check the syntax of the expression you have entered.
For further information on setting up queries and expressions in Graphs, see Graphs.
