Error in the Pie Legend for zero or negative values

[vvoovv]

If a data set contains zero or negative values, then 'dyn' array filled in plot2d/Pie.js containes only positive values from the data set. But filteredRun and slices arrays in widget/Legend.js contains all values.

This leads to the error in the following code snippet in widget/Legend.js:

dojo.forEach(slices, function(x, i){

this._addLabel(t.dyn[i], t._getLabel(x * 100) + "%");

}, this);

The error can be corrected if we substitute

var filteredRun = df.map(t.run.data, "Math.max(x, 0)");

with

var filteredRun = df.filter(t.run.data, "x>0");

in widget/Legend.js

The test file is attached. It should be run to charting/tests

I attach additional test case with array of objects. The fix to this ticket should be test against to test cases: 1) Array of numbers (e.g. chart.addSeries("Series A", [4, 0, 0, 1]); ) 2) Array of objects (e.g. chart.addSeries("Series A", [{y:4}, {y:0}, {y:0}, {y:1}]); )
