/*
BMI, Weight  and Feeling graphs are are hard coded in Overview.cpp
These graph require special handling in class gOverviewGraph.

Currently there are 4 graphs types, one of which is not used.
GT_BAR			Used by CPAP graph to make bar graphs for each day
GT_LINE			? Used for making a line ?
GT_POINT		? Used to display points instead of lines ?
GT_SESSION		?? NOT USED.

BMI, Weight  and Feeling graphs current use GT_LINE and not GT_BAR
The Overview Linecharts preference allows points to be displayed instead of lines.
