Description of problem:
Some graphs that show the legend at the right with min, max, avg have an erroneous value in the max.

Looks like an error of 100x in some highs.

Instead of a 9Gb max it is a 900Gb max.

Reproduce:
Take a look at the file system graphs for a single hard disk.

An error in org.rhq.enterprise.gui.coregui.client.inventory.common.charttype.MetricGraphData#normalizeUnitsAndValues

private MeasurementNumericValueAndUnits normalizeUnitsAndValues(double value, MeasurementUnits measurementUnits) {
        MeasurementNumericValueAndUnits newValue = MeasurementConverterClient.fit(value, measurementUnits);
        MeasurementNumericValueAndUnits returnValue;

        // adjust for percentage numbers
        if (measurementUnits.equals(MeasurementUnits.PERCENTAGE)) {
            returnValue = new MeasurementNumericValueAndUnits(newValue.getValue() * 100, newValue.getUnits());
        } else {
            returnValue = new MeasurementNumericValueAndUnits(newValue.getValue(), newValue.getUnits());
        }

        return returnValue;
    }

Which should work but needs further investigation why it does not.
