Greetings Michael,
So I tried it. It turns out that the order matters...
plot.setLimitsToFit(true);
plot.useTemplate(prevPlot, Plot.COPY_SIZE+Plot.X_RANGE+Plot.COPY_AXIS_STYLE);
plot.show();
When I first used setLimitsToFit, ages ago, it would only work after show.
It seems that now it also works before show. useTemplate does not seem to
work after show.
Thanks,
Fred
