Help plz with chart error!

[phidippus]

Hi fellows!

I need some help please!
I have 2 stacked column, with positive and negative values. However, column for positive values doesnt display starting from yAxis = 0, instead, start from bottom of chart, including for null values.
Negatives values (red column) is ok.
Any idea of what I am missing?..

-------------------------
grafico.setAnimate(true);
grafico.setStacked(true);
grafico.setMouseoverHighlight(false);
grafico.setBreakOnNull(true);

grafico.getAxes().put(AxisType.X, new CategoryAxis("Dates"));
Axis xAxis = grafico.getAxis(AxisType.X);
xAxis.setTickAngle(-50);

Axis yAxis = grafico.getAxis(AxisType.Y);
yAxis.setLabel("% field A");
yAxis.setTickFormat("%.1f%");

Axis y2Axis = new LinearAxis("Registros");
y2Axis.setMin(0);

grafico.getAxes().put(AxisType.Y2, y2Axis);
-------------------------



I appreciate any help! Thanks!
