====================================
Strip Chart Display
====================================

StripChart is a wxPython GUI application for viewing time traces of PVs as
a strip chart.  It feature interactive graphics, with click-and-drag
zooming, updating the plotted time range, saving figures as high-quality
PNGs, and saving data to ASCII files.  Stripchart is inspired somewhat by the
classic Epics Stripchart application written with X/Motif, but has many differences.

Usage
~~~~~~~~~


Plot details can be adjusted from the configuration form, available from
the Options Menu, and shown below.  From this frame, you can adjust trace
colors, symbols, line width and style, symbol size and styles, axes labels,
and the contents and location of a plot legend.  Text for titles, axes
labels, and legend can include latex strings for math/Greek characters.

From the main plot, Ctrl-C works to copy to the system clipboard, and
Ctrl-P will open a print dialog.
