With DATAMAN: A new command HKl_aniso_plot to plot LN<F> versus <1/Resolution> for bins of constant |h|, |k|, and |l|. This may help in detecting anisotropy in your crystal (provided it's along one of the axes).
The BIn_plot command has six new possible variables for the X-axis: H, K, L, H/A, K/B and L/C. Don't know if this is useful.
See the on-line manual for more details.
