Chart should be shown based on a value selection in list box using if nothing is selected it should NOT show chart for any value.

Chart should be shown based on a value selection in list box using  if nothing is selected it should NOT show chart for any value and it should show message "Please choose a value from the list Box to show this chart" .

I'm able to show the chart for just one selected value in the Listbox , which is perfect and that's what I need  but the problem is when I don't select any value in the Listbox , the chart shows for all 5000 values which is not required as it take some time to load . It would be great that this chart loads only if a value is selected in the Listbox and otherwise , it just shows message to choose the desired value from the list box.

Thanks in Advance .

Regards,

Arun

hello

use a formula like

if(getselectedcount(YourField)=1 in general tab to compute your graph only in this case

and use "error message" to display a personalized error msg
