Description sandra pazos 2015-02-03 10:50:24 EST 
The bar series stacked property doesn't work in correct way when there are negative values. Basically, the negative values in stacked bar series end up as positive values. The code below reproduces the problem: 
function draw() {
  Chart1=new Tee.Chart("canvas");
  Chart1.addSeries(new Tee.Bar([5,-3,2,-7,1]) );
  Chart1.addSeries(new Tee.Bar([4,4,-8,2,-9]) ); 
  Chart1.title.text="TeeChart for JavaScript";
  Chart1.title.format.font.style="18px Verdana";
  Chart1.series.items[0].stacked=true; 
  Chart1.series.items[1].stacked=true; 
  Chart1.draw();
  Chart1.title.format.font.gradient.visible=true;
  Chart1.draw();
}
