# 9. Using the Strip Chart Recorder

The EMC stripchart program is a modified version of GNOME stripchart program "gstripchart". This document is a modified copy of the GNOME stripchart documentation. For the original source code and/or documentation goto www.gnome.org.

EMC Modifications The following modifications were made to gstripchart program to turn it into emcstripchart.

- The "nml" configuration file option was added.
- The "emcmot" configuration file option was added.
- The "minimum" configuration file option was more completely implemented.
- An additional update timeout was added. This allows the data to be polled more often than display is refreshed.
- The text display is updated by a timer not just by clicking on it.
- The buttons "pause" and "go" were added. (They only pause and restart the plotting to give you more time to look at something, the EMC is not paused.)
- The "bottom" column was added.
- When the scale is readjusted, if the starting the starting minimum equaled the negative of the starting maximum the scale is modified so that it will maintain this symmetry about zero.
- Several of the defaults were changed.
- The bindtextdomain code was disabled.
- The original set of Makefile stuff using automake and autoconf was trashed to use a more EMC/RCS style makefile.
- Adds the -u -update-interval command line option.
- Linked in stripnmli.cc and stripemcmoti.cc and the RCS and EMC libraries.
