00004  * Data plotter script.
00005  * It just enters its input data into the data base of the GUI toolkit.
00006  * The actual plot updades will be done under the control of the GUI event
00007  * loop.
00008  * The script requires a preset character string context which contains the
00009  * (space separated) names for the GUI variable and data set.
