Pie Chart legend showing items that are not showed in the graph

[novito]

When doing a chart let's say of 4 items, where one of the items has a really low value compared to the others, even if it is shown in the legend, it is not shown in the chart. This is related to this question: http://stackoverflow.com/questions/8752518/google-charts-show-empty-items-in-legend -- Is there any option for the library to solve this?
