Description Flags
patch to add setArchiveInterval method to pmchart timecontrol and call it when a pmtime 'delta' packet is received none

Description Mark Goodwin 2013-07-04 06:34:20 UTC 
Description of problem: in archive mode, pmchart "forgets" the current update interval after loading a second view - it falls back to the original default update interval from when pmchart was first started - but only for the new chart(s) - existing charts are still correct (but obviously inconsistent with the new charts because they are plotted with different update intervals!)

Version-Release number of selected component (if applicable):
pcp-gui-1.5.9-1.x86_64

How reproducible: always

Steps to Reproduce:
1. run pmchart -a somearchive -c CPU
2. expose the time controls and change the update interval
3. load some another view, say Loadavg

Actual results:
pmchart creates the second view, but with the original update interval that pmchart was first started with

Expected results:
pmchart should create the second view using the current update interval

Additional info:
fix available - I'll post it. This is similar to an earlier bug (now fixed) where pmchart forgets the archive position when loading a new view - the update interval is affected too,

Closing out manually - issue has been long since fixed.
