Hi jharwood,
Can you provide more information about your x-axis time data? If you
are using the function, myXYGraph.PlotXY(dataX, dataY);, you could add
(or subtract) a constant to all data in the dataX array to change to
the GMT time zone. How to add a constant and the value of that
constant would be dependant of the time data you are passing to the
x-axis.
