There is what looks like a bug in LogarithmicNumberAxis::GetLabel that causes the sign of the exponent to be removed.

This happens because of the lines:

    if (m_logBase == 10.0 && !m_longExponent) {
        label.erase(label.length() - 3, 1);
    }

I think that the problem is because exponents on Linux are 2 digits + sign whereas on Windows they are 3 digits + sign. Therefore on Linux the sign is removed rather than the most significant digit.

This should already be fixed. The closure doesn't appear to have been copied across from the pbfordev github site.
