     //!!! todo: peak frequency style
 
     //!!! todo: transparent style from Colour3DPlot
 
-    //!!! todo: bin boundary alignment when in BinResolution
-
     //!!! todo: view magnitudes / normalise visible area
 
     //!!! todo: alter documentation for view mag stuff (cached paints
     //!!! do not update MagnitudeRange)
