Legend label is not displayed if label is empty string #773

Hi flot devs,

I am not sure whether it is a bug or not.
I am using flot to display a piechart.
with a sample dataset as follows:

var data= [
    {data:111, label:"test1"},
    {data:222, label:"test2"},
    {data:333, label:""}
];

The piechart displays 3 of them, however the Legend only displays 2 labels: 
test1 and test2.

I have played around with legend.labelFormatter , but even though my code runs 
"if label is empty then change label value to 'Blank'", the legend label is 
still not displayed.

Please advise
