obligatory selection in a graph

[#1]

I wanna have this:

In a graph it should be obligatory to select something from the "x" field.

and when you select this the graphic appears

what should i do ?

Hi there.

You can set a show condition for the graph (it's in the design tab) to something like:

=GetSelectedCount(field) = 1

Thus, if there's one (and only one) value selected on the field, the graph will be visible, otherwise it won't.

Kind regards,

Ernesto.

Thank ya.

One more question

Can i put in the graph "Please enter ...." ?

You can use the same concept that @ernesto garcia says, but in calculated condition and error mensaje

Yes, you can put your message in several places, the title bar, the help text, or superimpose a text box over the graph with a transparent background, among other options.

Kind regards,

Ernesto.
