Archive-Retrieval Tool for EPICS

TChart uses the QCustomPlot
TChart source code and software are licensed under the GNU
GPL except as noted otherwise.
TChart was created as a replacement for the Motif-based EPICS StripTool
TChart contains the following functionality:
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.
enabled, the strip-chart display can seemlessly scroll from the live
archived data of the stripped process variables.
A retrieval engine for saved strip-charts allows displaying of
saved strip-chart data.
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 a demo archiver is supplied.
from single-PV files can be retrieved and displayed for a user-selected
time-interval. This allows viewing of data taken by different
during the selected time-period.
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.
TChart does not
contain an on-line help system. Use the help files which are supplied here.
