TChart Functionality Summary
TChart contains the following functionality:
A strip-charting engine allows strip-charting of up to 10 EPICS process variables while
(optionally) saving data to a temporary disk file. At the end of strip-charting, the user has the
option to save or discard the data. The strip-chart data is saved into comma-separated-variable files
and also split into single-PV-files.
If enabled, the strip-chart display can seemlessly scroll from the live strip-chart to archived
data of the stripped process variables.
A retrieval engine for saved strip-charts allows displaying of saved strip-chart data.
An archive-retrieval interface allows retrieving and displaying archived data. The archive
retrieval engine must be supplied as a Qt plug-in.
With the distribution a plug-in for the TRIUMF Trar archiver is supplied.
Data from single-PV files can be retrieved and displayed for a user-selected time-interval. This
allows viewing of data taken by different TChart instances during the selected time-period.
Retrieved Strip-chart or archive data can be used as a background for a live strip-chart. This
allows comparing the time-behaviour of live incoming data with historical data samples. The
historical data are time-shifted so that the start-times coincide.
TChart contains a "demo" data generator which can be used for demonstation purpuses. A demo
archiver plug-in is also supplied.
