Click once on the chart to activate it. Then click once on the y-axis to select it. Then use the Inspector and choose Chart (at the top of the window it is 3rd from right). At the bottom of that is a dropdown that says "Number Format". Click on it and there will be US and European currency listed.

If you select bars in the chart, and go to the graphics inspector tab you can choose the color, gradient, image etc. for the selected bar.
Thanks for that.
