if anyone had charts metrics  for only 2 days being saved here is the solution 
There is default pattern of .* with 1day retention in the  storage-schemas 
As the order is top to down 
we have to add netapp.capacity schemas to above this config or it will be only saved for 1 day as this pattern matches all other patterns below 
 
 
for RHEL I had to move these to bottom 
"/opt/graphite/conf/storage-schemas.conf"
[default_1min_for_1day]
pattern = .*
retentions = 60s:1d
