This script plots the MARTe2 ATCAIop samples stored in MDSplus
All of the plots may be panned/scaled by dragging with
the left/right mouse buttons. Right click on any plot to show a context menu.

To change EPICS EO, WO use. e.g.
caput -a ISTTOK:central:ATCAIOP1-WO 14 0.191 0.174 -0.036 -0.044 0.183 0.126 0.020 0.140 -0.461 -0.572 0.022 -0.262 0.475 0.353
