I’ll be using the E. coli project that’s
included in Epi Info 7 – you can open it
up and follow along. I'm in the visual dashboard and I've already loaded the E. coli project
with the Food History form that's included
in Epi Info 7. If you look at the top this
dataset has 359 records. Now we'll navigate to the Pie chart analysis gadget. The main
variable in this dataset is called "State,"
now we'll click Run. Here is the basic pie
chart. If you want to change the display settings, you’ll go to the gadget configuration panel
and open Display options. I can change the color palette, I can make the chart 3D, or
I can change some of the annotations. Just remember that once you run the chart, if you
don’t like the color palette, or the way
that the annotations show, you can go back
and change them. Then experiment and find what you want. The Annotation percent determines
where the label shows – either inside or
outside the chart. The default is 20% but
I’ll change it to show how it works. At
20%, some of the labels are inside the pie
chart. I’m going to change it to 90% and
now all the labels are outside the pie chart.
I’ve changed the color palette to Montreal
and the annotation percent to 40. Now I’ll
click Run. Here are the results. You have
just been shown how to create a pie chart in the
visual dashboard. Thanks for watching and
look for more user support videos coming soon.
