You are probably not setting the MeterAxis.setAxisTickSpace and MeterAxis.setAxisMinorTicksPerMajor properties correctly to reflect the range that you want. The following method that creates a meter with a range of 23 to 26, works fine.
Note the lines:
meteraxis.setAxisTickSpace(0.2);
meteraxis.setAxisMinorTicksPerMajor(5);
that place a minor tick mark every 0.2 units, and a major tick mark every (0.2 * 5) = 1.0 units.
