All I want is to see is the stacked values on the bar series. I don't want to include the line series. So, when clicking on the stack button, the value are stack but the Y Axis on the right doubles the value. It confuses me. And if i set a min and max, then I click to stack, the line disappear. How to select only the bar series to create the stack ? Can you help me on that, please ? Thank you
