how to create the custom charts?
how to create a custom charts? for example the donut shapes, but for the data can be automatically adjust (like a available charts on keynote)
Keynote-OTHER, Mac OS X (10.7.3)
Keynote and Numbers do not have a tool for making Donut Graphs. There are ways to make them using HTML, but I prefer to cheat:
1 Create your first graph as a pie chart and add a circle of solid color to the center
2. If you need more, take a screenshot of the pie chart with the center fill and drag the screenshot into Preview - in Preview > Select Tool (pulldown from Toolbar) > Instant Alpha and remove the inner filled circle and outer fill then Save As > PNG with Alpha
3. Drag your new hollow shape into Keynote. This chart can be placed over another pie chart with a filled center (the fill should match the background)
Not as graceful as a special tool but can get the job done quickly - changing the data requires starting it over since at least one of your donuts my be an image rather than a pie chart with variable data.
Try it. If you need more specific tools, Google Donut Shaped Charts for starts.
Good luck
