After I make a pie chart I can't select another object and align it using the align tool. The pie chart is resisting. I'll click the "Horizontal Align Center" and "Vertical Align Center" buttons but nothing moves.
Also if you try to "Expand" the pie chart nothing happens. The only way I could find to disconnect the graph from the data was to ungroup it a couple of times. Once I do that I can align the chart with another object.
Well actually to a certain degree you can align the other objects to the graph if you draw a rectangle around the pie chart or graph and use the fit toart command and then choose align to artboard orientation and in thn selct the other objects they will move to align tot he artboard containing the graph (chart.)
As you have found out, ungroup a copy of the graph. align the copy as desired, turn on the smart guides, snap the original graph into the copy, and delete the copy.
The difference between the workaround and the real solution is extra clicks and mouse moves which is the case with a lot of things in Illustrator including those without any bugs.
