Selection

Hello!

If I have a listbox that have some options, which can then be displayed in a few different charts. But if I do not make any selections in the listbox, I do not want it to appear some lines i the chart. Is it possible to get to do it so that there is no lines i the diagrams from the begining?

One way is to check "Conditional" in the expression tab of the chart properties and then add:

Len(GetFieldSelections(fieldname))>0

as condition

(fieldname is the name of the field in your listbox)

Hello again!

Thanks for this, but if I make a selection in one of my list boxes so nothing happens, it just says "conditions for calculation are not met" and it may not be right, for it if I do not make a selection, it should read something like that. But if I do any of my choices, then it should come up numbers?

Some line or all line in the chart?

if all line means, use calculation condition in general tab. for some expresssion means, use conditional in expression tab.

Try like this

=GetSelectedCount(FieldName)
