Yes, now everything seems to work just perfectly:

graph_label = '65.46 G' for 65.4600
graph_label = '65.48 G' for 65.4800
graph_label = '65.50 G' for 65.5000
graph_label = '65.52 G' for 65.5200
graph_label = '65.54 G' for 65.5400
graph_label = '65.56 G' for 65.5600


Thanks about a megabunch or two for a really nice tool!
