As you can see from the code above the component uses a simple technique to specify the position of the bar series. If a series MultiBarMode is set to Clustered it forms a cluster with the previous series or group of series. In the context of the example c2bar1 is displayed next to the stack formed by c1bar1 and c1bar2.
If a series MultiBarMode is set to Stacked or StackedPercent it is stacked on the previous bar series with Clustered mode or in case such series does not exist to the previous bar series with mode Series. Multiple bar series can be stacked on a bar series with mode Clustered or Series. The type of stacking (stacked or stacked percent) is determined by the last series in the stack.
