There are sections of data missing in the weekly and daily charts.
Eg. On the weekly chart I have the data below displaying.
W 14/2011 to W 22/2011 looks OK
W 40/2010 to W 13/2011 is missing
W 14/2010 to W 39/2010 looks OK
W 41/2009 to W 13/2010 is missing
W 15/2009 to W 40/2009 looks OK
It is all present when I look at the raw data in the historical data manager.
