Graphical Analisys doesn't save filters

Hello,

Im using a query form to make a search, after that i select the parameters and click on graphical analisys.

After that i set up the graphic as i want, i use filters to not show null values on both parameters, when the graphic is the way i want i save the graphical analisys.

When i access the saved graphic it loads showing all the nulls i filtered out before saving.

Whats is the point o saving a graphic if everytime you want to see it you need to reconfigure all the filters?

Thanks.
