In Excel 2003 you used to be able to move data points in a chart (or ranges
of a slice in a pie chart) simply by dragging&dropping them directly in the
chart - which, in turn, would modify the corresponding value in the worksheet.

In Excel 2007, you can't do that: data points in a chart are not
"draggable', which is a shame, since that was a very useful tool to have. For
example, sometimes you may want to tweak the appearance of a plot (you know
how you'd like it to look like, and accept the numerical values that make
that shape possible). Or you might want to adjust the proportions in a pie
chart visually, directly on the chart, rather than numerically, by trying
various values in the worksheet.

I hope to see this very useful feature implemented in Excel again. Thanks.
