How to create a plot with strings?

I need create a plot like this:(similar)

Data:

category= { } with 90x1 could be Beef & Pork, Chicken & Fish or Salads

fat and calories is a 90x1 too

I try to do:

figure(1)
xlabel('Fat')
ylabel('Calories')
if category=="Beef & Pork"
  plot(fat, calories, 'd')
end
if category=="Chicken & Fish"
  plot(fat, calories, 'o')
end
if category=="Salads"
  plot(fat, calories, 'x')
end

But only read the first element.
