MyaPlot vs. LivePlot

MyaPlot and LivePlot are OPS tools for displaying archived and live-published (respectively) EPICS variables in a simple plotting utility.

CREX has a standard JMenu/General Tools/MyaPlot set up in the OPS account "hacuser". The hacuser is accessible from Hall A computers using the aliased command "NewTools", or directly by executing the command, and following the menus until finding the plotting tools:

xterm -T NewTools -e ssh -X hacuser@hlal00.acc.jlab.org 'MyMenu'

Plotting Tools

• MyaPlot - A tool for plotting parameters stored in the OPS EPICS Archive. You can go back as far as data is kept for a given variable
  • Doesn't automatically update to keep track with fresh data
  • You can take the current set of displayed variables and switch to a LivePlot session through the right-click context menu
• LivePlot - A tool for looking at current data accessible through EPICS, regardless of whether it is archived
  • Doesn't go back farther in time than the most recently opened LivePlot session containing the displayed variables
• Panguin - A tool for plotting Parity DAQ Data, live (in "watchfile" mode) or previously analyzed
  • See Online Plots for more information
• Ciprian's Python Plotting tool - Ciprian wrote a MatPlotLib tool for displaying calculated quantities for keeping track of PREX/CREX Collimator temperatures, accessed by doing the following:
  • ssh -Y adaq@adaq2
  • cd ~/ciprian
  • python collimatorInfo.py
  • It will display all data from time of launch until the present, giving the collimator In and Out temperatures, and the difference
  • These temperatures must remain < 70 C and the difference should not exceed 15 C (if it does then call the RC)

Standard set of Mya/LivePlot Charts

From the hacuser OPS account, in the /usr/opsuser/hacuser/.myaPlot/CREX/ folder, the following strip charts are updated copies from PREX II running:
