good idea, but I am under severe time restrictions, so I cannot think of redoing it all - for now.
I actually had sth like what you propose in the very beginning, but I cannot return to it now: I have a cycle_group now and at some point I had three different formulas, each one with a condition, a variable to govern them and a button to change the variable. I would do it that way again if I had the time.
I have found a way though it doesn't look quite as nice (I cannot use a frame and drop_shadow and all that): There is the possibility of adding free text to a diagram ("presentation" tab of the properties dialog). That free text can also contain formulas.
It was quite time-consuming, but I copied all the formulas one by one from my variables and put them in that free_text_area, separated by linebreaks (chr(10)) and formatted the background and all I could.
The result, as I said, does not look quite as nice as a textbox, but at least now I have but one element and there is no disturbance on the other sheet.
P.S.: This is what you (Rob Wunderlich) were/ are going to propose right now ;-)
I had not thought of it before but I think you can use a macro triggered to hide or show your textbox depending of what object is shown in your container
Using something like that :
Set ContainerObj= ActiveDocument.GetSheetObject("CT01") '
'get index of currently active tab/object of container
if activeIndex=0 then
go see http://community.qlik.com/thread/30250 there is an interesting example for you I think
Thank you all!
Since I am under time restrictions, I will leave it as it is for now. I have created some "text in chart" items and just added formulas to background_colour and text_colour to make them blend into the background when the user has made any selection so I don't risk showing values which are calculated and in that case wrong.
The only backdraw is that I cannot make the background_colour a colormix, these options are not active.
