I'm using Excel 2003 and need to display a chart showing how a stack of
colours chnages over time for 3 different products. The closest chart is
either the stack of colours - but this is done in percent, or the 'Tubes' -
which is done with the axes reversed/wrong way round .

Can anyone help with how to swap the axes for the tube chart type OR show
the stack of colours chart type using values not percentages?

Thanks
