GLineGraph Widget

A Gtk3/GLib2/cario GUI application which demonstrates the use of GTK+ for producing xy line graphs. This widget once created allows you to add one or more data series, then add values to those series for ploting. The X point is assumed based on arrival order. However, the Y value or position is based one the current scale and the y value itself. If the charts x scale maximum is 40, or 40 points, the 41+ value is appended to the 40th position after all points are shifted left and out through pos 0.

Packaged as a gtk widget for ease of use.

A lgcairo.c example program is included to demonstrate the possible use of the codeset.

There is also GtkDoc API documentation in ./docs directory.

FEATURES:

* GlgLineGraph API Reference Manual in ./docs directory.
* Unlimited data series support.
* Accurate scaling across a wide range of X & Y scales.
  - Using values ranges above or below 1.
* Rolling data points, if number of x points exceed x-scale. (left shift)
* Ability to change chart background color, window backgrounds colors, etc.
* Popup Tooltip, via mouse-button-1 click to enable/toggle.
  - Tooltip overlays top graph title, when present.
* Data points are time stamped with current time when added.
* Some key debug messages to console: $ export G_MESSAGES_DEBUG=all
* Auto Size to current window size; i.e. no-scrolling.
* point-selected signal tied to tooltip, to display y value under mouse.

REQUIREMENTS:

Gtk3/Glib2 runtime support.

* the following packages may need to be installed to build program and
  for runtime of binaries on some platforms.

glinegraph - { this package }
gtk-devel  - { GTK+ version 3.10 is minimum package level required}
glib-devel - { version 2.40, packaged with GTK+ }
