Is there a way to avoid this Error? (All expressions are disabled)

[EliGohar]

Hi All,

This is the message we get for all the charts when the app has not yet run:

I know that if I run the app then this message will disappear, but is there a way to show other message, something like "No data"? 

We want to show something more friendly before the app ran.

Thanks for your help,

Eli.

you can use Data handling options , where in calculate condition you can use a condition "if(Date( today(),'DD/MM/YYYY') =Date( ReloadTime(),'DD/MM/YYYY'),1,0)" and display message "No Data". The issue with this approach if the last reload time is same as todays date, it will not work.  we can think of more option to use system functions to understand if qvf refresh has taken place or not.
