Real time dashboard data not refreshing.

[richnavis]

I've created a the following search that returns results when first run using 5 minute real time from the time picker. However, as the time axis refreshes the lines in the graph do not, eventually there is no data drawn on the graph. Any ideas?

index=perf_1 counter="IO Data Bytes/sec" |timechart avg(Value) by instance

I have very similar problem also with perfmon. I though it happened because of delay in data, so I've tried to set time to search as rt-30s, the problem still exists, Some Ideas?
