History Features:
Average method: useful for common view, using like default (Can’t show single min/max)

DESY realizations:
In StripTool 2.4b8 from JLAB was adding StripHistory_fetch() call, so all StripUser can create history browser using own local archiver.
At DESY we using archive record from IOC first (usually in this record have about 200 more recent history points ) and if we need more points we get data from our VAX/VMS archiver.
Request for archive record - channel access call . Request for archiver - Sun RPC call to VAX/VMS
RPC server which extract data from archiver files.

EPICS workshop Trieste’9915
Goals, problems,future realizations
Goals:– StripHistoryTool allows create real “data browser”.– More “one click” technology.– There are no difference between current and history data for
user.– For showing big array of data we need different data reduction
methods. Problems:
– Inside of StripTool we need cut fast get_current_data part and slow get_history part Now we have problem for showing new data during history request.
– “Reload configuration” could shift dataRingBuffer pointer to current time.

EPICS workshop Trieste’9916
Goals, problems,future realizations
In future:– Add possibility show 2 additional min/max curves for each
current curves (it’s standard for physics plotting).– Try create common call to archiver and add this features to
common StripTool.
