Area Charts / Stacked area
Multiple series rendered in the same area chart will overlap one another by default. To avoid that, you have the option to stack these series on top of one another, so that the data values at each x-value are summed. In an area chart, the value for each series will always be stacked relative to the preceding one.
You can enable the stack feature through the seriesDefault,stack setting.
For more information inspect the seriesDefault option in the documentation.
