I have a simple 1-series bar chart where each bar has a nominal value. I can plot this fine with the data labels and axis representing the value for each bar but I\'d like t
try this.percentage
It's pretty well documented in the highcharts API as well.

EDIT
Since you'd need it for non-stacked series, you'd need to get the total before generating the graph... The function below adds up your values into one variable which you can use in your formatter function later.
function arrayTotal(arr)
{
var total = 0;
for (var i = 0, value; value = arr[i]; i++)
{
total += value;
}
return total;
}
