Graphite-Module shows empty graphs

I installed Graphite according to this tutorial and it’s working like a charm, as you can see at this image:

But in my icingaweb dashboard all graphs are blank!

That’s /etc/icinga2/features-enabled/graphite.conf content:

object GraphiteWriter "graphite" {
  host = ""
  port = 2003
  enable_send_thresholds = true

…and /etc/icingaweb2/modules/graphite/config.ini content:

url = ""
insecure = "1"

default_time_range = "1"
default_time_range_unit = "hours"
disable_no_graphs_found = "1"

Solved! I enabled perfdata and statusdata icinga2 features:

icinga2 feature enable perfdata statusdata
