! \internal Prepares the internal tick vector, sub tick vector and tick label vector. This is done by calling QCPAxisTicker::generate on the currently installed ticker. If a change in the label text/count is detected, the cached axis margin is invalidated to make sure the next margin calculation recalculates the label sizes and returns an up-to-date value. */
