From the forum:
This is a suggestion for the meter charts. It would be
nice to have the option to tell the meter renderer to
show the needle as pegging the maximum value (or just
beyond it) rather than having an exception thrown if
the value of the needle exceeds the maximum value. It
should also show this value in the chart.
Right now the only way I can handle a value that is
outside the max range of the meter is to resize the
meter range so it is back in it.
