IBM FlashSystem 9500 Storage does not display graphics

Hello everybody, 

I recently installed Xormon NG and configured my IBM FlashSystem V9500 Storages.

Connection tests work perfectly.

The same settings used in Xormon NG are used in Stor2RRD and in this second the collection works perfectly, however in Xormon NG the graphics are blank.

I apologize that my English may be a little confusing, as I used Google Translator 

Thank you in advance for the help.
