Draws a horizontal bar graph on the display.
Where Display is the name you have given to the device in Project Designer.
The X co-ordinate of the bottom left X of the graph.
The Y co-ordinate of the bottom left Y of the graph.
The value to be shown in the graph. Between 0 and graphMax.
The maximum value that will be shown in the graph.
The maximum length of the graph in display character cells.
You cannot mix horizontal graphs and vertical graphs on the display at the same time - this is due to the limit of custom characters provided by the displays.
The Sparkfun serLCD product does not allow the use of custom characters - so the graph is very low resolution.
