Illustrator Charts

Another Step-by-step Tutorial by Veerle

This tutorial is made in Adobe Illustrator CS2, however it should be no problem if you use an older version.

select Pie Chart Tool
Select the Pie Chart Tool in the toolbox.
If you double click the graph icon in the Toolbox you can set the preferences of the graph.
The preferences are available (and will be applied) even after you've created your graph.

Draw a square (press shift key while dragging your mouse)
Draw a square (press shift key while dragging your mouse).

enter data in the datasheet
Enter your data in the datasheet (labels in the first row and values in the second).

result in grayscale
The result should look similar to this.

adding the colors
Use the Direct Selection Tool (the white pointer / press A) to select only 1 piece of the pie to change its color.

add white line of 1pt
Use a different gradient for each slice of the pie and add a 1pt white line.

Alter the gradient's direction
Alter the gradient's direction of each slice 1 by 1. In Illustrator CS2 you can do this all in once by selecting the entire pie. Don't forget to do the same for the legend.
Notice that I've changed the rectangles to squares.

add extra circle with 4pt white border
Add a circle with a 4pt border and transparant fill on top of the pie (pure to add an extra nice touch).

add light shadow to the pie
Instead of using the dropshadow effect I've decided to draw another circle below the pie to create the soft shadow.
The circle has a radial gradient from black to white, 40% opacity and the mode is set to Multiply.
If you want to use the dropshadow feature, you need to expand the graph (Object > Expand) which means you can't alter (update) your pie data anymore.
If you want to expand your graph, you need to make sure your datasheet is closed.

add drop shadow to legend colors
Use the Direct Selection Tool to select the legend colors and go to Effect > Stylize > Drop Shadow

Choose Multiply as mode and enter 10% of opacity, an x and y offset of1.5 mm and no blur (0 mm)
Choose Multiply as mode and enter 10% of opacity, an x and y offset of 1.5 mm and no blur (0 mm).

end result
That's it!

You can still update your data by control + click / second mouse button click on the pie and choose Data in the contextual menu.
