Example:

if you have 400 pixels, and if you have 800 rows to display,
how is rrdtool going to display unconsolidated data? It isn't!

Look at my site for details on normalization and consolidation.

In short: if you do not want consolidation to happen, make sure
every RRA has only one PDP per row. Also make sure you do not
display more rows than you have pixels.

And make sure you understand the difference between normalization
and consolidation.  Step/heartbeat/xff have to do with other stuff
than consolidation.
